This is an insert bearing secured on the shaft by means of an eccentric locking collar, with the inner ring extended on one side. Sealing is provided by a stamped steel washer fitted with a rubberized lip. The bore diameter (d) is 20 mm, and the bearing weighs 0.16 kg. Further dimensions read from the catalogue drawing are: B = 31.0 mm, C = 14 mm, D = 47 mm, c = 12.8 mm, m = M 6 x 0.75, s = 7.5 mm, c0 = 6.6 mm, d1 = 26.9 mm, d2 = 33.0 mm. The eccentric locking collar allows the inner ring to be clamped directly onto the shaft without an additional adapter sleeve, which simplifies mounting and dismounting in an insert-type housing. The extended inner ring on one side gives additional support length for shaft engagement. The stamped washer with a rubberized lip seals the bearing against dust and moisture ingress at the rotating interface. Dimensionally and constructionally, this bearing corresponds to SKF YET 204.
