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.
