Original Bosch rubber ring — part 1610206021 — a molded rubber bearing cover / damping bushing designed to sit in the hammerhead assembly around the SDS‑Plus bearing area to cushion and seal the mechanism.

This genuine Bosch rubber ring is sized and shaped to match factory tolerances for a clean fit and easy installation: it replaces the worn or torn rubber cap that protects the bearing and helps reduce vibration and grease migration around the striker/bit interface. Bosch power tool parts like this are commonly listed as “rubber ring” or “bearing cap” for rotary‑hammer assemblies.

Example compatible models (listed in Bosch spare‑parts diagrams and parts catalogs) include GBH 2‑24 DSR, GBH 2‑24 DFR, GBH 2‑24 DS and related GBH/GBH‑series rotary hammers GBH 2-24 DFR / GBH 2-20 S and GBH 24 VR. Use the part 1610206021 where the OEM parts diagram shows the rubber ring in the hammerhead assembly.

If your drill’s rubber cap is split, missing, or allowing excess play or grease leakage at the SDS interface, this original Bosch replacement ring restores the intended fit and protection so the tool runs as designed.
