52,0x2,0 MM

Bosch 1610210160 — original Bosch O‑ring (sealing ring) designed for rotary-hammer service and repair. This small but critical seal measures 52.0 × 2.0 mm (ID × cross‑section) and is used to restore proper internal sealing where the tool’s piston/gear housings meet.

A durable genuine Bosch replacement, the 1610210160 is listed on Bosch exploded parts diagrams (position 104 on GBH 5‑40 assemblies) and is a common spare for the GBH series—examples include GBH 5‑40 (and D/DCE variants) and GBH 5‑38 / GBH 5‑38 X ; it also appears across several related GBH model types.

If your rotary hammer is leaking grease, losing impact power, or letting dust into the mechanism, fitting this original Bosch O‑ring returns the seal and helps prolong the life of the tool. This is a standard, easy-to-replace part typically stocked among power tool parts for GBH rotary hammers.

Sold individually as the Bosch 1610210160 sealing ring — check the type/serial plate on your tool against the GBH model listings to confirm fitment before installation.
