Angular Contact Bearings

The comprehensive selection of CIE angular contact bearings fit applications that require the absorption of force in both radial and axial directions. Manufactured in both traditional steel and ceramic materials, these bearings are commonly applied in such high speed applications as turbines, jet engines, dentistry equipment and machine tools.


Duplex Pairs

Any radial bearing can be duplexed to remove radial play, to increase rigidity and improve performance. Please contact an CIE representative for pricing and delivery.


Radial Ball Bearings

CIE offers a complete selection of radial ball bearings, the most common type of bearing configuration. A radial ball bearing consists of two concentric, symmetric rings (or races) that are configured to support a load across the radius of the bearing. While most radial designs also support modest axial loads, significant off-axis load bearing capability is commonly addressed through the use of an Angular Contact bearing.


Types of Bearings
There are many types of bearings, each used for different purposes. These include ball bearings, roller bearings, ball thrust bearings, roller thrust bearings and tapered roller thrust bearings.
Ball Bearings
Ball bearings, as shown below, are probably the most common type of bearing. They are found in everything from inline skates to hard drives. These bearings can handle both radial and thrust loads, and are usually found in applications where the load is relatively small.

In a ball bearing, the load is transmitted from the outer race to the ball, and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and outer race at a very small point, which helps it spin very smoothly. But it also means that there is not very much contact area holding that load, so if the bearing is overloaded, the balls can deform or squish, ruining the bearing.

Roller Bearings
Roller bearings like the one illustrated below are used in applications like conveyer belt rollers, where they must hold heavy radial loads. In these bearings, the roller is a cylinder, so the contact between the inner and outer race is not a point but a line. This spreads the load out over a larger area, allowing the bearing to handle much greater loads than a ball bearing. However, this type of bearing is not designed to handle much thrust loading.

A variation of this type of bearing, called a needle bearing, uses cylinders with a very small diameter. This allows the bearing to fit into tight places.

Ball Thrust Bearing
Ball thrust bearings like the one shown below are mostly used for low-speed applications and cannot handle much radial load. Barstools and Lazy Susan turntables use this type of bearing.

Ball thrust bearing
Roller Thrust Bearing
Roller thrust bearings like the one illustrated below can support large thrust loads. They are often found in gearsets like car transmissions between gears, and between the housing and the rotating shafts. The helical gears used in most transmissions have angled teeth -- this causes a thrust load that must be supported by a bearing.

Roller thrust bearing
Tapered Roller Bearings
Tapered roller bearings can support large radial and large thrust loads.

Tapered roller bearings are used in car hubs, where they are usually mounted in pairs facing opposite directions so that they can handle thrust in both directions
