Ball Bearings

Ball bearings are the most widely used type of rolling element bearing in the world today due to their versatility and overall performance. They are produced with high quality materials and exacting tolerances. Each of the individual components such as the rings, balls, cage, shield or seal, and lubricant contribute to the bearings ability to perform in a variety of applications and environments. Our radial ball bearings accommodate moderate to heavy radial loads, with low to moderate axial loads in either direction.

• Deep Groove - Single row deep groove ball bearings are manufactured in a varied range, both of standard design and various constructive versions. Our deep groove ball bearings are non-separable, support high speed operation, and accommodate axial loads in both directions and radial loads.

• Angular Contact - Angular contact bearings better support "combined loads" (loading in both the radial and axial directions). An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to try and separate the races axially. Angular contact bearings are constructed so the contact angle of the inner race should be matched to the relative proportion as that on the outer race. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load.

• Self-Aligning - Self-Aligning Double Row Ball Bearings consist of two rows of balls and a spherical outer ring raceway. The spherical outer raceway allows them to work in applications where misalignment exists, whether from mounting or shaft deflection during operation. This construction prevents undue stress on the rest of the bearing assembly.

• Thrust - Thrust ball bearings are manufactured in two versions: single and double direction, with neither being able to take radial loads. Thrust ball bearings, single direction, are used to take single direction axial loads. Such bearings consist of a shaft washer, a housing washer with flat support surface and a ball cage. Thrust ball bearings, double direction, can take axial loads in both directions. Such bearings consist of a shaft washer, two housing washers with flat support surfaces and two ball cages.
