This insert bearing is secured on the shaft by means of an eccentric locking collar, with the inner ring extended on one side. The bore diameter (d) is 25 mm, and the weight is 0.19 kg. Further dimensions read from the catalogue drawing: B = 31.0 mm, C = 15 mm, D = 52 mm, c = 14.0 mm, m = M 6 x 0.75, s = 7.5 mm, c0 = 7.8 mm, d1 = 30.5 mm, d2 = 37.5 mm. The dimensional-constructional equivalent is SKF YET 205. Sealing is provided by a stamped steel washer with a rubberized lip, which keeps grease inside the housing and limits ingress of contaminants at the shaft passage. The eccentric locking collar allows quick mounting and secure fixation on the shaft without additional fasteners, while the one-sided extended inner ring gives a defined seating surface for the locking mechanism. This construction of the SA series is suited for shaft mounting where the eccentric collar fixation method and the specified bore diameter of 25 mm match the application requirements.
