Insert Full Ceramic Bearings

Full Ceramic Insert Bearings are made entirely of ceramic material and are superior to common Steel Insert Bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM’s, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Applications such as cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment, robotics and optics. Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), Alumina Oxide (Al2O3) or Silicon Carbide (SiC.)
Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction. Ceramic balls require less lubricant and have a greater hardness than steel balls which will contribute to increased bearing life. Thermal properties are better than steel balls resulting in less heat generation at high speeds. Full Ceramic bearings can have a retainer or full complement of balls, retainer materials used are PEEk and PTFE.

Full Ceramic Insert Bearings can continue to operate under extremely high temperatures and are capable of operating up to 1800 Deg. F. Ceramic is much lighter than steel and many bearings are 1/3 the weight of a comparable steel bearing. Full Ceramic Insert Bearings are highly corrosion resistant and will stand up to most common acids, they will not corrode in exposure to water or salt water. And finally Full Ceramic Insert Bearings are non-conductive.

Full Ceramic Insert Bearings and wide inner ring bearings are used for mounting on shafts without the need for shoulders or adapters. The bearing is locked in place through setscrews or a locking collar. The inner ring usually extends on both sides of the bearing to provide extra shaft support, but some styles only extend on one side. Sometimes Full Ceramic Insert Bearings are simply standard radial bearings that fit into a housing and these bearings may be purchased as stand-alone products to use as replacements. While standard radial ball bearings must be pressed into a machined shaft, using special installation tools, insert bearings can be slip fit directly onto the shaft.

Lubricating and reassembling wheel bearings

Removing the outer races
Clean the hub and races well with paraffin or white spirit. Then drive the races away from each other. The inner and outer races may be of different sizes. If so, begin with the smaller one.

Use a socket as a 'drift' (pusher). Choose one which fits through the larger race to rest against the smaller race.

Lengthen the socket with an extension piece and tap this gently with a heavy hammer to expel the race. Use a bigger socket to force the other race out in the opposite direction.

If the races are the same size, remove the first one with a flat-faced punch and heavy hammer, tapping alternate sides and working evenly around the race so as not to tilt and jam it. Be careful not to scratch the inside of the hub.

When the first race has been removed, free the second race, using a socket as a drift.

Checking and cleaning the bearings

Clean all parts well with paraffin or white spirit. Avoid getting grease on the brakes when cleaning the stub axle.

LUBRICATING THE BEARINGS

To replace bearings, tap the outer races into the hub using the old races as drifts. Be sure to fit a tapered-roller race the right way round.

Pack the bearings with an approved type of bearing grease - consult the car handbook or a dealer if in doubt. Find out also how much grease to apply. On some hubs the central area is heavily loaded with grease, but other types need only a light coating. Always fill the bearings themselves with as much grease as they can hold, forced in between the races.

With roll bearings, coat the outer race thickly with grease. Spin the rollers in their cage on the inner race while rubbing grease into every crevice.

Put the inboard inner race into its outer race; or tap it on to the stub axle with a tubular drift if this is more convenient. Do not forget to fit any spacer between the bearings.

With either type of bearing, now insert the new grease seal. Be sure to fit it the right way round. If it fits flush with the inner edge of the hub, tap it gently home with a wooden block. If it is recessed, use a socket to press it in.

If you are doing only routine lubrication, the outer races remain on the stub. Inspect them: very slight indentations are allowable, but if there is noticeable pitting or scoring you need new bearings.

For the inner races and the rollers or balls make no allowances at all. Any blemish is unacceptable and means renewal of the bearing.

Reassembling the bearings and hub

Lightly grease the stub axle, including the threaded end and the shoulder at the base. Keep grease off brake parts.

Carefully push the hub on to the axle, taking care not to knock out the inner race of an outer ball bearing with the axle end.

If the hub sticks, tap it with a soft-faced hammer. Insert the inner race of an outer roller bearing.

Fit the thrust washer with its chamfered side towards the bearing. Screw on the hub nut, then adjust the hub. Position a castellated nut so that it lines up with the split-pin hole - by easing the nut, back, not forward - or fit the nut cover if there is one.

Insert a new split-pin, head uppermost, and open the legs. Trim the legs so that they will not prevent the dust cover being fitted. Reassemble the brakes.

General Types of Bearings and How They Work

Generally speaking, a bearing is a device that is used to enable rotational or linear movement, while reducing friction and handling stress. Resembling wheels, bearings literally enable devices to roll, which reduces the friction between the surface of the bearing and the surface it’s rolling over. It’s significantly easier to move, both in a rotary or linear fashion, when friction is reduced—this also enhances speed and efficiency.

How Bearings Work

In order to serve all these functions, bearings make use of a relatively simple structure: a ball with internal and external smooth metal surfaces, to aid in rolling. The ball itself carries the weight of the load—the force of the load’s weight is what drives the bearing’s rotation. However, not all loads put force on a bearing in the same manner. There are two different kinds of loading: radial and thrust.

A radial load, as in a pulley, simply puts weight on the bearing in a manner that causes the bearing to roll or rotate as a result of tension. A thrust load is significantly different, and puts stress on the bearing in an entirely different way. If a bearing (think of a tire) is flipped on its side (think now of a tire swing) and subject to complete force at that angle (think of three children sitting on the tire swing), this is called thrust load. A bearing that is used to support a bar stool is an example of a bearing that is subject only to thrust load.

Many bearings are prone to experiencing both radial and thrust loads. Car tires, for example, carry a radial load when driving in a straight line: the tires roll forward in a rotational manner as a result of tension and the weight they are supporting. However, when a car goes around a corner, it is subject to thrust load because the tires are no longer moving solely in a radial fashion and cornering force weighs on the side of the bearing.

Types of Bearings

There are numerous different kinds of bearings that are designed to handle radial load, thrust load, or some combination of the two. Because different applications require bearings that are designed to handle a specific kind of load and different amounts of weight, the differences between types of bearings concern load type and ability to handle weight.


    Ball Bearings

Ball bearings are extremely common because they can handle both radial and thrust loads, but can only handle a small amount of weight. They are found in a wide array of applications, such as roller blades and even hard drives, but are prone to deforming if they are overloaded.


    Roller Bearings

Roller bearings are designed to carry heavy loads—the primary roller is a cylinder, which means the load is distributed over a larger area, enabling the bearing to handle larger amounts of weight. This structure, however, means the bearing can handle primarily radial loads, but is not suited to thrust loads. For applications where space is an issue, a needle bearing can be used. Needle bearings work with small diameter cylinders, so they are easier to fit in smaller applications.


    Ball Thrust Bearings

These kinds of bearings are designed to handle almost exclusively thrust loads in low-speed low-weight applications. Bar stools, for example, make use of ball thrust bearings to support the seat.


    Roller Thrust Bearings

Roller thrust bearings, much like ball thrust bearings, handle thrust loads. The difference, however, lies in the amount of weight the bearing can handle: roller thrust bearings can support significantly larger amounts of thrust load, and are therefore found in car transmissions, where they are used to support helical gears. Gear support in general is a common application for roller thrust bearings.

                                                      

     Tapered Roller Bearings

This style of bearing is designed to handle large radial and thrust loads—as a result of their load versatility, they are found in car hubs due to the extreme amount of both radial and thrust loads that car wheels are expected to carry.


    Specialized Bearings

There are, of course, several kinds of bearings that are manufactured for specific applications, such as magnetic bearings and giant roller bearings. Magnetic bearings are found in high-speed devices because it has no moving parts - this stability enables it to support devices that move unconscionably fast. Giant roller bearings are used to move extremely large and heavy loads, such as buildings and large structural components.

Ball Roller Bearings Manufacturer

Ever since man began to need to move things, he has used round rollers to make the job easier. Probably the first rollers were sticks or logs, which were a big improvement over dragging things across the ground, but still pretty hard work. Egyptians used logs to roll their huge blocks of stone for the pyramids. Eventually, someone came up with the idea of securing the roller to whatever was being moved, and built the first "vehicle" with "wheels." However, these still had bearings made from materials rubbing on each other instead of rolling on each other. It wasn't until the late eighteenth century that the basic design for bearings was developed. In 1794, Welsh ironmaster Philip Vaughan patented a design for ball bearings to support the axle of a carriage. Development continued in the nineteenth and early twentieth centuries, spurred by the advancement of the bicycle and the automobile.

 There are thousands of sizes, shapes, and kinds of rolling bearings; ball bearings, roller bearings, needle bearings, and tapered roller bearings are the major kinds. Sizes run from small enough to run miniature motors to huge bearings used to support rotating parts in hydroelectric power plants; these large bearings can be ten feet (3.04 meters) in diameter and require a crane to install. The most common sizes can easily be held in one hand and are used in things like electric motors.

This article will describe only ball bearings. In these bearings, the rolling part is a ball, which rolls between inner and outer rings called races. The balls are held by a cage, which keeps them evenly spaced around the races. In addition to these parts, there are a lot of optional parts for special bearings, like seals to keep oil or grease in and dirt out, or screws to hold a bearing in place.

Almost all parts of all ball bearings are made of steel. Since the bearing has to stand up to a lot of stress, it needs to be made of very strong steel. The standard industry classification for the steel in these bearings is 52100, which means that it has one percent chromium and one percent carbon (called alloys when added to the basic steel). This steel can be made very hard and tough by heat treating. Where rusting might be a problem, bearings are made from 440C stainless steel.

The cage for the balls is traditionally made of thin steel, but some bearings now use molded plastic cages, because they cost less to make and cause less friction.

 The Manufacturing Process

There are four major parts to a standard ball bearing: the outer race, the rolling balls, the inner race, and the cage.


1 Both races are made in almost the same way. Since they are both rings of steel, the process starts with steel tubing of an appropriate size. Automatic machines similar to lathes use cutting tools to cut the basic shape of the race, leaving all of the dimensions slightly too large. The reason for leaving them too large is that the races must be heat treated before being finished, and the steel usually warps during this process. They can be machined back to their finished size after heat treating.

2 The rough cut races are put into a heat treating furnace at about 1,550 degrees Fahrenheit (843 degrees Celsius) for up to several hours (depending on the size of the parts), then dipped into an oil bath to cool them and make them very hard. This hardening also makes them brittle, so the next step is to temper them. This is done by heating them in a second oven to about 300 degrees Fahrenheit (148.8 degrees Celsius), and then letting them cool in air. This whole heat treatment process makes parts which are both hard and tough.

3 After the heat treatment process, the races are ready for finishing. However, the races are now too hard to cut with cutting tools, so the rest of the work must be done with grinding wheels. These are a lot like what you would find in any shop for sharpening drill bits and tools, except that several different kinds and shapes are needed to finish the races. Almost every place on the race is finished by grinding, which leaves a very smooth, accurate surface. The surfaces where the bearing fits into the machine must be very round, and the sides must be flat. The surface that the balls roll on is ground first, and then lapped. This means that a very fine abrasive slurry is used to polish the races for several hours to get almost a mirror finish. At this point, the races are finished, and ready to be put together with the balls.
