Decoding the designation

X2S — Timken’s prefix for a cone spacer, the ring that sits between the front faces of the two cones in a two-row assembly.

430900 — the Timken item number identifying this spacer’s ground width and bore.

What these specs mean in practice

The spacer’s ground width is what sets the bench endplay of the finished two-row assembly, here 0.010 in. Fixing the setting at manufacture means the assembly goes together at a known internal clearance instead of being set by hand on the bench, so shaft location and running clearance are repeatable from build to build. A 9 in bore means the ring slides onto the same shaft seat as the cones it spaces.

Mounting data

The spacer mounts on the shaft between the two cone front faces, inside the housing bore, and is clamped up solid with the cones when the assembly is drawn against its shoulder. Each Timken spacer is ground to the bench lateral of the components it is supplied with.

Unit Quantity: 1 Pc. One X2S-430900 cone spacer ring.
