Description
Overview:
This Ext E‐Ring JIS is a Genuine Makita Part designed for securing components on Makita hammer drills, including HR2610 and HR2611F. It is an external retaining ring that fits into a groove on a shaft or pin to prevent axial movement, keeping assemblies aligned and stable under vibration. Manufactured from durable spring steel with a protective, corrosion‐resistant finish, the ring offers reliable retention in high‐load, high‐frequency applications typical of rotary hammer mechanisms. As an OEM component (OEM No. 257336-0), it provides the correct profile and tension to match Makita specifications, supporting smooth operation and long service life. Suitable for both professional users and DIY maintenance, it is a small but critical part for keeping your drill performing as intended.

- JIS E‐type profile for consistent, secure axial retention on grooved shafts and pins

Typical Applications:
Used to retain gears, bearings, pins, and selector components within Makita rotary hammer assemblies.
