Genuine Bosch thrust ring — part no. 1610102073. This compact, washer‑style thrust ring (thrust washer) is made for the axial support and alignment inside Bosch rotary‑hammer gear/impact assemblies; it keeps rotating and sliding parts running true and prevents premature wear in the hammer mechanism.

Fits many Bosch GBH/PBH rotary‑hammer models — commonly referenced for GBH 2‑26 series and related 2‑series tools (for example GBH 2‑26, GBH 2‑24D and the GBH 18V‑26) and appears in parts lists for several PBH2800RE / PBH300FRE / PBH2900FRE models. Confirm the part number against your tool’s exploded diagram or parts list, but this is the ring used in those gear/impact sub‑assemblies.

Sold as the individual genuine Bosch replacement ring (part number formats shown as 1610102073 or 1 610 102 073). It’s a direct, original Bosch spare intended to restore proper axial spacing and reduce looseness or knocking in the hammer gearbox when the original ring is worn or damaged.

If your parts diagram shows 1610102073 in the gearbox/drive section, this is the correct original Bosch thrust ring to replace that worn washer and get the tool operating smoothly again.
