Bosch 1600502023 — genuine Bosch intermediate ring / rubber sleeve bearing designed as a direct replacement for the rotor bearing seat on many Bosch grinders and rotary tools.

This part is a rubber insulating sleeve that stabilizes and isolates the rotor’s ball bearing (acts as an insulating spacer around the bearing to reduce play and damp vibration).

It’s made to work with a 607-series bearing — nominal bearing dimensions 7 × 19 × 6 mm (bore × outer Ø × width).

Example compatible tools include many Bosch angle grinders and related models such as GWS 6‑115, GWS 6‑125, GWS 7‑115 / 7‑125, GWS 11‑125, GWS 700 / 750 / 780 / 850 (including CE variants), PWS 13-125 CE and GBH 4-28 DFR rotary models where the same bearing arrangement is used.

If you’re repairing a grinder and need reliable genuine Bosch power tool parts for power tools to restore smooth running and reduce noise or axial play, this 1600502023 intermediate ring is the correct, easy‑to‑fit replacement for the listed models.
