Decoding the designation

368S — Timken cone, 2-1/32 in bore, 360 series.

363D — Timken double cup, 90 mm OD: one outer ring with two raceways, taking two cones.

X1S-368S — Timken cone spacer for the 368S, setting the axial distance between the two cones.

-90101 — Timken assembly number for this cone, double cup and spacer combination.

*3 — Timken Class 3 precision: tighter tolerance and lower runout than the standard Class 2.

What these specs mean in practice

The two roller rows sit back to back in one double cup, carrying radial load and axial load in both directions. The spacer fixes the bearing setting between the cones.
