Bosch 2600290033 — Seal ring (genuine Bosch)

Restore a worn belt-sander seal with this original Bosch seal ring, part number 2600290033. It’s the small but critical rubber/elastomer seal that sits around the roller/shaft area to keep abrasive dust and debris out of the bearing and housing, helping the sanding unit run smoothly and prolonging bearing life.

Direct fit for Bosch 75-series sanders — commonly used on the PBS 75 A / PBS 75 AE belt sanders and the GBS 75 A / GBS 75 AE models (for example model codes 0603270103, 0603270503 and 0601274703). If your PBS/GBS 75-series sander has a torn, hardened or missing seal where the roller meets the housing, this part replaces it without modification.

What you’re getting: a genuine Bosch seal ring manufactured to the original fit and finish so it seats correctly in the roller housing and restores the factory dust barrier. It’s a simple, low-cost replacement that prevents premature wear on rollers and bearings and keeps sanding performance consistent. For reference it’s listed in the PBS 75 spare-parts diagram as the seal ring for the roller area.

Quick tip for installation: remove the sanding belt and roller assembly to access the housing, clean the cavity of heavy dust before pressing the new seal into place, and check the roller spins freely once reassembled. This part is intended as a direct Bosch replacement for the 75-series belt sanders noted above.

No follow-up needed — if your sander is a PBS/GBS 75-series and the old seal is damaged, this genuine Bosch 2600290033 seal ring is the straightforward replacement to get it back to reliable operation.
