LJT4.1/2M RHP Single Row Angular Contact Ball Bearing 4.1/2 Inch Bore Sealed while requiring roughly 25% lessRHP Single row angular contact ball bearings can accommodate axial loads in one direction only. A single row bearing is typically adjusted against a second bearing. The bearings are non separable and the bearing rings have one high and one low shoulder. The low shoulder enables a large number of balls to be incorporated in the bearing, giving it a relatively high load carrying capacity. Boundry dimensions (inch) d: 4. 1 2 D: 8 B: 1. 15 16 Basic load
