Dimensions - d (inside diameter) 50mm Dimensions - D (outside diameter) 80mm Dimensions - B (width) 20mm Timken Metric taper roller bearing priced cup & cone together 50mm inside x 80mm outside x 20mm 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.
