TIMKEN 29685 - 29620-B | Tapered Roller Bearings - TSF

TIMKEN Bearing 29685 - 29620-B

Like the TS bearing design, the TSF design 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. TSF bearings have flanged cups to facilitate axial location and accurately align seals in through-bored housings.
