A Timken 36626 tapered roller bearing cup — the outer race of a TS single-row tapered roller bearing, 8.000 in outside diameter and 0.9063 in wide, produced to Timken Class 2 precision. The cup is a single hardened and ground ring carrying the outer raceway.
1 Pc. Cup only. The matching cones are the Timken 36690 and 36686.
A tapered roller bearing splits into two halves that are supplied and stocked separately, because the cup presses into the housing while the cone assembly goes onto the shaft. The cup carries the outer raceway and nothing else. Class 2 is a tighter Timken precision grade than the standard commercial class, held on outside diameter and raceway form, and it is specified where housing fit and running accuracy have to be controlled more closely than normal.
The through-hardened bearing steel is rated for continuous service from −54 °C to 120 °C.
The cup presses into the housing bore squarely and seats fully against its shoulder, with the force applied to the back face rather than to the raceway. A tapered roller bearing is set on assembly by adjusting the axial position of one race, so the cup is installed with the housing arrangement that provides that adjustment. Cup and cone are matched at manufacture as a raceway pair.
Where two cones share a single housing bore in an indirect-mount pair, Timken supplies the Y1S-36626 cup spacer to set the spread between the two cup positions.
36626 is an industry-standard cup number, so a cup marked 36626 from another tapered roller bearing maker shares the envelope and the mating cone list. A Timken 36626-2 is the same cup at the same Class 2 precision. The 36620 is a different cup in the same numbering family with a different outside diameter, so it is a related size rather than a substitution.
