Single-row Angular Contact Ball Bearings - Radial - Nachi Ameri
The raceways of both the inner and outer rings of this bearing type are made with a set contact angle. Single-row Angular Contact ball bearings can sustain radial, axial or composite loads, however, any axial load must be in one direction. Larger contact angle type has better axial load capability. Small contact angle type

Combination Angular Contact Ball Bearings - Nachi Ameri
Normally Single Row Angular Contact Ball Bearings are used as a combination of two or more bearings. Three types of combinations are available; 1) DB, back to back 2) DF, face to face 3) DT, tandem; Clearance of matched set are adjusted before shipment, care should be taken to prevent mixing of parts from other sets.

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.
