Timken 69354-98012, a complete two-row tapered roller bearing assembly in a 2TS arrangement: two complete single-row bearings mounted together with a spacer between their cups.
Bore: 3.543 in (90 mm). Outside Diameter: 6.303 in (160.1 mm). Design Units: Inch. Number Of Rows: 2. Bearing Type: Double-row tapered roller bearing, 2TS-DM. Arrangement / Configuration: 2TS, two cups spacer-set.
Unit Quantity: 1 complete assembly. The assembly comprises two 69354 cone assemblies (inner races with rollers and cages), two 69630 cups as separate outer races, one per row, and one Y1S-69630 cup spacer. It is a complete five-piece bearing.
Cone: 69354, two fitted. Cup: 69630, two fitted, one per row. Cup spacer: Y1S-69630 — the Y1S- prefix is Timken’s designation for a cup spacer, the component that sits between the two 69630 cups and sets the assembly’s internal end play. Assembly suffix: -98012, identifying this specific five-piece build. Searchable variants: 69354-98012, 6935498012, 69354 98012.
A two-cup, spacer-set arrangement carries radial load, thrust in both directions and axial location of the shaft, with real resistance to overturning moments from the row spacing. It is built from standard single-row components, so individual parts are widely available and the end play can be re-established with a reground or replacement spacer. Against that, it adds one more joint in the stack and gives a slightly less rigid outer-race path than a one-piece double cup.
The ground width of the Y1S-69630 spacer establishes the setting. The five pieces are a matched set, and the spacer width is specific to this build.
69354 and 69630 are industry-standard inch tapered designations available from several manufacturers, and same-number substitution is generally valid on geometry. Match on the assembly number when replacing a two-row unit, because the spacer width is specific to the build. The same Y1S- cup-spacer convention appears on Timken 95500-95925 (Y1S-95925).
