GRW High Precision Ball Bearings
High precision ball bearings in grades up to ABEC 9 with bores from 1 to 30mm and comparable inch dimensions
Spindle ball bearings are angular contact ball bearings which, depending on the type, have a relieved land on the inner ring (AC2) or the outer ring (AC1). Axial forces can thus only be accepted in one direction. Spindle ball bearings can be used as single ball bearings or as ball bearing pairs in back to back, face to face or tandem arrangement. GRW spindle ball bearings have the following characteristics:
These characteristics allow the ball bearings to run very accurately at high speeds. At the same time these ball bearings are very rigid and have minimum vibration levels: The standard type is: AC1 TA Relieved on outer ring shoulder, ball bearing cannot be disassembled, solid phenolic retainer guided on outer ring. Other types including ball bearings with removable inner rings are available upon request.
