Genuine Bosch 1610283036 rotary shaft lip (oil) seal — precision-molded to keep lubricant in and dust and debris out of the gearbox and hammer mechanism; part of the Bosch power tool parts lineup.

Measures approximately 30 × 41 × 7 mm (ID × OD × thickness) and is manufactured from oil-resistant nitrile (NBR) for durability under heavy use and exposure to grease.

Direct-fit replacement for many Bosch rotary hammers including the GBH 2‑24, GBH 2‑26, GBH 2‑28 series and GBH 18V‑26 / GBH 36 V‑LI models — restores proper sealing to prevent oil leaks and reduce contaminant ingress.

Simple drop‑in install for trained technicians or maintenance pros; replacing a worn 1610283036 seal quickly returns factory-level lubrication control and helps extend bearing and gearbox life.
