Description
Overview:
The Bosch Backup Ring (OEM No. 1610200029) is a genuine spare part used to support sealing elements inside Bosch rotary hammer drills and similar machinery. Made from a hard‐wearing polymer, this ring sits behind an O‐ring to prevent extrusion under pressure, reducing the risk of leaks and protecting internal components. It is designed for the seal stacks found in tools such as the GBH 4-32 DFR and GBH432DFR, where vibration, impact loads, and temperature changes are common. With precise dimensions and material specifications matched to Bosch assemblies, it helps maintain correct clearances and consistent sealing performance. Selecting the genuine part ensures reliable fit, predictable durability, and long service life in both site and workshop conditions.
Key Features:
- Genuine Bosch part for assured compatibility and performance (OEM 1610200029)
- Supports O‐rings to prevent extrusion and leakage under pressure
- Durable polymer construction resists wear, oils, and common workshop greases
- Stable in high-vibration, impact-heavy environments typical of rotary hammers
- Precision fit to maintain seal integrity and internal tolerances
- Straightforward to fit during routine servicing or a full seal rebuild
- Helps extend service intervals and reduce unplanned downtime
- Suitable for demanding site use and regular professional maintenance
Typical Applications:
Used in sealing assemblies within Bosch rotary hammers to maintain grease containment and pressure control in gearboxes and percussion mechanisms. Ideal during scheduled overhauls, seal replacements, or repairs addressing oil or grease leaks. Also suitable for similar industrial tools where O‐rings require anti‐extrusion support to ensure consistent sealing performance.
Also known as:
Anti‐extrusion ring, O‐ring backup, support ring, back‐up washer, seal support ring. These terms refer to the same component used to reinforce an O‐ring in a gland, improving resistance to pressure and movement, and helping maintain a reliable seal over the service life of the tool.
