A Timken 29675/29622D two-row tapered roller bearing assembly, 2-3/4 in bore by 4-1/2 in outside diameter, comprising two 29675 cones running in one 29622D double cup. Timken catalogues this combination as the 29675-90146 assembly.
The D suffix on the 29622 cup marks a double cup: one outer race carrying two raceways, which takes two cones rather than one. 29675 is the cone number. A Timken -90xxx number denotes a complete assembly, which is how this combination is catalogued.
Two opposed rows carry thrust in both directions and resist moment loading, where a single row would let the shaft tilt under offset load. Because both rows share one double cup, the housing takes a single press fit and the row spacing is fixed at manufacture rather than shimmed on the bench.
One assembly: two 29675 cones and one 29622D double cup, two rows.
The double cup is pressed into the housing bore on the cup face rather than the raceway and seated square against its shoulder. Each cone is fitted to its own shaft seat, and running clearance is set at the shaft on assembly.
The component numbers are the Timken 29675 cone and the Timken 29622D double cup, catalogued together as 29675-90146. A single 29675 cone with a single 29622 cup is a one-row bearing and is a different product, not a substitute.
