This insert bearing carries a spherically ground outer ring and locates on the shaft by means of an eccentric locking collar, with the inner ring extended on both sides for a fixed direction of rotation. Bore diameter d is 45 mm, weight is 0.85 kg. From the catalogue drawing: B = 56.3 mm, C = 22 mm, D = 85 mm, c = 32.5 mm, m = M 10 x 1.25, s = 21.4 mm, c0 = 20.4 mm, d1 = 56.6 mm, d2 = 63.5 mm — these values should be checked against the drawing on the product card during mounting. The bearing is sealed on both sides and factory-filled with lithium grease class 2, which sets the running condition at installation without a separate lubrication step. The eccentric locking collar fixes the inner ring to the shaft for one constant direction of rotation only, so the mounting orientation must match this requirement. The spherically ground outer ring allows the housing to accommodate shaft misalignment within the insert design. Dimensional and constructional equivalent: SKF YEL 209.
