Timken Imperial taper roller bearing priced cup & cone together 1.3750 inch (34.925mm) inside x 2.8750 inch (73.025mm) outside x 0.9375 inch (23.812mm) width Timken offers the most extensive line of tapered roller bearings in the world. Tapered roller bearings consist of four interdependent components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements) and the cage (roller retainer). Tapered roller bearings are uniquely designed to manage both thrust and radial loads between a rotating and non-rotating member. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads. Industries: Aerospace, agriculture, automotive, heavy truck, cement, aggregate, coal, oil and gas, construction, gear drives, machine tools, mining, paper, metals, rail and wind. Benefits: Enhanced performance in demanding applications.
