This insert bearing locks onto the shaft by means of an eccentric locking collar, with the outer ring spherically ground and the inner ring extended on both sides. The bore diameter (d) is 40 mm, weight is 0.73 kg. Further dimensions read from the catalogue drawing: B = 56.3 mm, C = 21 mm, D = 80 mm, c = 32.5 mm, m = M10 x 1.25, s = 21.4 mm, c0 = 19.8 mm, d1 = 52.3 mm, d2 = 60.3 mm. The eccentric collar fixing is designed for a fixed direction of rotation, so the shaft must not run in reverse once mounted. The bearing is sealed on both sides and factory-filled with lithium grease, class 2, which covers relubrication for the service life of the seals. The spherically ground outer ring allows self-alignment within the housing seat, which is useful when the housing bore is not perfectly aligned with the shaft. Dimensional and constructional equivalent: SKF YEL 208.
