Information on Durobal® Bearings

In operational parameters for bearings, consideration must be given to load, speed, life, lubrication and environment. Bearing performance is a complex function of many variables, including design, materials, methods of manufacturing and specific applications. Each of these variables must be taken into account, with attention paid to their relationship to each other as well as to the end-use application.

The basic Durobal® design consists of four major components: inner race, outer race, ball retainer cage and balls. Other custom designs may require the addition of a shield and/or seal and, in the case of the Full Ball Complement, there is no ball retainer cage. These custom bearings begin as close tolerance injection molded components. All raceways (ball tracks) are fully machined to match the radial curvature of the ball selected. This "match," along with the use of statistical process control manufacturing, ensures the production of high quality bearings. The use of proprietary bearing compounds to produce the retainer cages enhances and increases the life of the bearing.

Designs

Radial Open: for applications in which the bearing is subjected to radial or thrust loads or a combination of both

Radial Shielded and Sealed: for applications in unclean environments where contaminants are kept away from the raceway area

Angular Contact: designed for high thrust (axial) loads typically from one direction

Thrust Bearing: two basic designs to carry a pure thrust load between two mating surfaces

Full Ball Completment: designed for very high loads; equipped with an extra deep ball groove with no cage and a full complement of balls
