The Timken 1931-B is a tapered roller bearing cup of the TSF type, belonging to Timken's 1900 imperial series. Part number 1931-B designates a single flanged cup designed for use with a corresponding tapered roller bearing cone in opposing-pair shaft configurations. The flanged design allows the cup to be backed against the flange face so the housing bore can be machined straight through, eliminating the need for stepped housings and simplifying seal alignment in through-bored applications. Per Timken published specifications for the 1931 series, the cup has an outside diameter of 2.375 inches and a cup width of 0.625 inches. The flanged cup configuration is a TSF variation on the standard TS single-row tapered roller bearing, sharing the same cone components as the non-flanged 1931 cup. Typical applications for this series include machine tool spindles, gear reduction units, automotive transaxles, and industrial transmissions. The item is presented in its original Timken orange and black packaging. Timken is an American bearing manufacturer with over a century of engineering history in tapered roller bearing design and production.
