Angular contact bearings are designed such that there is an angle between the races and the balls when the bearing is in operation. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that o ...

Matched Pair bearings are Angular contact ball bearings that are suitable for applications that require high accuracy and high-speed performance. Bearings with a smaller contact angle are more suitable for high-speed rotation; those with a larger contact angle are more suitable for high load applications. Angular contact ball bearings are often pre ...

Flange mounted bearings are used when a shaft axis is perpendicular to the bearing mounting surface. Available in 2, 3, or 4-hole configurations, flange mounted bearings provide a method of accurate mounting fits and load support. 2-bolt flanged bearings have a diamond shaped flange with 2 mounting holes. Most 3-bolt flanged bearings have a circul ...

Needle bearings use a roller style rolling element to reduce friction of a rotating surface. Needle Bearings have a high load carrying capacity with a very small cross section height. They are available with or without an inner ring. The needle rollers are guided parallel to the axis using a cage retainer, thrust bearings can also be supplied with ...

Needle Roller & Cage Types use a roller style rolling element to reduce friction of a rotating surface without the need for an inside or outside race. Needle Roller & Cage Types have a high load carrying capacity with a very small cross section height and consist of a retainer and rollers only. The needle rollers are guided parallel to the axis usi ...

An O'ring is a mechanical gasket in the shape of a circle; it is a loop of pliable material with a disc-shaped cross-section, designed to be seated into a groove and compressed during assembly between two or more parts, creating a seal.

The O'ring may be used in static applications or in dynamic applications where there is relative motion betw ...

15% of the weight of Oil filled powder metal bushings is the oil that has been impregnated by using hot oil and a vacuum system under pressure. The air is sucked out of the powder metal bushing pores creating a void that is then filled with oil. Over time oil leaves the bushing. Oil comes out by centrifugal force, heat and leaching out if imprope ...

Oil seals have a flexible lip that rubs against a shaft or housing to prevent the leakage or contamination of fluids and debris. For proper installation, the seal lip should point towards the lubrication being contained. Some oil seals have a spring to help keep the lip in contact with the shaft. The sealing orientation and direction is important ...

New One Way Bearing series by Boca Bearings. Drawn cup needle roller clutches have a small radial section height and are also commonly known as One Way Bearings or Anti-Reverse Bearings. This design uses the same small radial section as drawn cup ne ...

Engineers often hesitate to use Plastic Bearings in their designs, because they have trusted steel bearings for years or they just don't think plastics can handle demanding applications or environments. Plastic Bearings, however, can endure extreme temperatures, heavy loads and high speeds. Some other benefits to Plastic Bearings are listed below. ...

Pressure Roller Bearings are coated with urethane rubber and fixed by special processing on its outer ring to keep its rotation accuracy. Under the proper radial loading, the coefficient of friction and hardness of rubber are useful for handling paper or for carrying mechanisms, guide bearings and idle bearings. Pressure Roller Bearings are commonl ...

The purpose of a radial bearing is to reduce rotational friction and support loads. This is achieved by using two races to hold the balls and to spread the load through the balls. As the bearing race rotates it causes the balls to rotate. The ball provides for substantially less rolling resistance and coefficient of friction than if two flat surfac ...

They consist of a spherically-shaped inner ring and a cylindrical bore for mounting on a sh ...

A Self Aligning Bearing has two rows of balls and a one, concave spherical raceway in the outer ring. As a result the bearing is self-aligning and insensitive to misalignments of the shaft in relation to the housing.

Most spherical ball bushings consist of a plain bearing and ball bushing inside a lined, c ...

Tapered roller bearings can take both large axial forces, and radial forces due to their cup and cone design. The inner and outer races are separable and shaped like a cone; the rollers also have a taper. This tapered design distributes the weight and results in a bearing capable of handling relatively high loads. The larger the half angles of thes ...

Thrust bearings are designed for side or axial loads, and cannot handle much radial load at all. The rolling element in a thrust bearing can be a ball, needle or roller. Thrust bearings come in both metric and inch sizes. Dimensions to consider when searching are the bore, the outside diameter and the overall width. Operating specifications to con ...
