This insert bearing carries a spherically ground outer ring locked onto the shaft by an eccentric locking collar, with the inner ring extended on both sides. The bore diameter (d) is 65 mm, weight is 2.50 kg. Dimension B is 85.7 mm, C is 34.1 mm, D is 120 mm, c is 62.0 mm, the locking element m is M 10 x 1.25, s is 34.1 mm, c0 is 44.0 mm, d1 is 82.5 mm, and d2 is 86.0 mm — check the catalogue drawing for exact positions of these dimensions. The eccentric locking collar design fixes the inner ring to the shaft for one constant direction of rotation only, so mounting orientation must be observed during installation. Double-side sealing keeps lithium grease class 2 in the bearing and contaminants out, allowing operation without additional external sealing arrangements. The spherically ground outer ring seats in a housing that permits self-alignment, which is useful where minor shaft misalignment is present. The dimensional and constructional equivalent listed is SKF YEL 213.
