This insert bearing carries a spherically ground outer ring locked onto the shaft by an eccentric locking collar, with the inner ring extended on both sides. The bore diameter d is 50 mm, weight is 0.93 kg. From the catalogue drawing: B = 62.7, C = 22, D = 90, c = 35.2, m = M 10 x 1.25, s = 24.6, c0 = 23.2, d1 = 62.5, d2 = 69.9 mm; refer to the drawing on the product card for the exact location of each dimension. The eccentric collar fixing is designed for a constant direction of rotation, so the shaft must not be expected to reverse under load without checking the locking arrangement. Both sides are sealed, and the unit is factory-filled with lithium grease class 2, which covers running without additional relubrication under normal service. The symbol HC 210 AV12 corresponds dimensionally and constructionally to SKF YEL 210.
