Special Bearings Thanks to its flexible manufacturing facilities GRW can provide a wide range of special ball bearings in addition to standard and highprecision ball bearings made of chrome and stainless steel. The special characteristics are: • special shapes • special lubricants • special treatments Furthermore we also manufacture rotationally symmetrical turned parts. Special Shapes Two-row ball bearing with step in outer ring Crowned outer ring Linear guide ‘V’ Groove and inner shaft Rotationally symmetrical turned part Rotationally symmetrical turned part Rotationally symmetrical turned part Bearing unit for incremental shaft encoder Bearing unit in read/sort unit for banking documents 36
Spindle/Angular Contact Ball Bearings 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: •Production in high-precision quality (grade P5, P4, P2 or ABEC5, ABEC7, ABEC9) • One-part solid phenolic retainer (TA, TB, see page 41) • Larger number of balls than in standard ball bearings • Contact angle 15° (other angles available upon request) •Available with steel balls or ceramic balls • The preload for ball bearing pairs is selected according to the applied load (light, medium or heavy preload) • Spindle ball bearings are generally lubricated with oil 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. 37
