Original Bosch rotary shaft lip seal (part no. 1610290028) — a precision radial sealing ring designed to stop oil and grease leaks around the rotary shaft of demolition hammers. The seal measures approximately 18 × 31 × 6 mm (inner Ø × outer Ø × thickness) and installs in the armature/shaft housing to restore proper sealing and extend tool life.

Fits a range of Bosch demolition hammers and SDS-max rotary hammers — for example: GSH 11 E, GSH 10 C, GBH 11 DE, GBH 7 DE and related GBH 7-45/7-46/7-46 DE series models — so you can replace the worn lip seal with the original Bosch part and get the unit back to reliable service.(Confirm the 10 digit product code from the side of the machine to confirm fit before purchasing) This genuine Bosch spare is a common item among professional power tool parts for repairing leaks and preventing contamination of internal components.
