Radial Ball Bearin

The bearing ring grooves are circular arcs made slightly larger than the radius of the ball. The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders). Deep Groove ball bearings can sustain radial, axial, or composite loads and

Precision Rolling Bearin

Any Combination of NACHI FLUSH GROUND. Precision Beanings will provide the desired preload, obviously facilitating bearing handling. There are three basic combinations: * Back to back combination (DB). * Face to face combination (DF). * Tandem combination (DT) which require no adjustment so the optimum.

Bearings for Specific Applicati

Wheel Assembly Bearings. To obtain predetermined preload clearance after attachment, initial internal clearance has setup. Preload adjustment during an assembly process is unnecessary. The type with a built-in seal has unnecessary seal fixation during an assembly process. Lightweight, compact and handling is easy.
