Tapered Roller Bearings - TS (Tapered Single) Imperial On The Timken Company

This is the most basic and most widely used type of tapered roller bearing. It consists of two main separable parts: the cone (inner ring) assembly and the cup (outer ring). It is typically mounted in opposing pairs on a shaft.
