This insert bearing uses a spherically ground outer ring locked onto the shaft by an eccentric locking collar, with the inner ring extended on both sides. This design fixes the shaft in one direction of rotation only. The bore diameter (d) is 40 mm, with outer diameter D = 80 mm and width B = 56.3 mm; further mounting dimensions read from the catalog drawing are C = 21, c = 32.5, s = 21.4, c0 = 19.8, d1 = 52.3, d2 = 60.3, and the locking thread is m = M10 x 1.25. Unit weight is 0.73 kg, relevant only for handling during mounting. The bearing is sealed on both sides and pre-packed with lithium grease class 2, so no external relubrication is required during operation. The eccentric locking collar allows quick clamping onto the shaft without additional fasteners, provided the shaft turns in a constant, single direction, matching the locking mechanism of this construction. Dimensional and constructional equivalent: SKF YEL 208.
