This insert bearing mounts on the shaft by means of an eccentric locking collar, holding a spherically ground outer ring and an inner ring extended on both sides, which is intended for one fixed direction of rotation. Bore diameter (d) is 45 mm, weight is 0.85 kg. Further dimensions 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. The bearing is sealed on both sides and pre-packed with lithium grease class 2, so no separate seal or relubrication fitting needs to be added at assembly. The eccentric locking collar fixes the inner ring to the shaft without a separate adapter sleeve, which simplifies mounting where the shaft rotates in one constant direction only. Dimensional and constructional equivalent: SKF YEL 209.
