TimkenTwo-Row Tapered Roller Bearing Assembly 2-3/4 in Bore, 4-1/2 in Outside Diameter, Two Cones, Double Cup and Cone Spacer

Product Description

What this part is

A Timken 29675-90146 two-row tapered roller bearing assembly, 2-3/4 in bore by 4-1/2 in outside diameter. The assembly is supplied complete: two 29675 cones, one 29622D double cup and one X1S-29675 cone spacer.

Decoding the designation

A Timken -90xxx number denotes a complete assembly rather than a component, so 29675-90146 is the assembly part number built on the 29675 cone. The D suffix on the 29622 cup marks it as a double cup, carrying two raceways in one outer race. The X1S- prefix identifies a cone spacer, which sets the axial distance between the two cones.

What these specs mean in practice

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 the spacer and the double cup fix the row geometry at manufacture, the internal setting comes from the assembly itself rather than from shimming on the bench, which is what makes a -90xxx assembly repeatable across rebuilds.

Quantity and configuration

One complete assembly: two cones, one double cup, one cone spacer.

Fitting notes

The double cup is pressed into the housing bore on the cup face and seated square. The cones and the spacer go onto the shaft in the ground order, and the parts are kept together as a set because the spacer is matched to them.

Interchange guidance

The component numbers are the 29675 cone, the 29622D double cup and the X1S-29675 cone spacer. A single 29675 cone with a single 29622 cup is a one-row bearing and is a different product from this two-row assembly, not a substitute for it.
