As TIMKEN bearing distributor, Nodes bearings have TIMKEN 1986-1931-B bearings in stock, TSF (Tapered Single with Flange) Imperial , Tapered roller bearings.

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.
