The NTN Bower 458SHD is a tapered roller bearing cone with a 45 mm bore and a cone width of 29.317 mm. It carries a 111 kN dynamic load rating and a 142 kN static load rating, belongs to catalog series 455 and is built to ABMA Class 2 (Inch) tolerance. The cone is the inner ring of the bearing and runs with a matching cup. Tapered rollers on conical races let one bearing take radial and axial load together, and the large contact area suits heavier loads than a ball bearing.
