Description
Overview:
This Cushion Ring is a genuine Makita part for rotary hammer drills, supplied under OEM No. 421955-0. It is a tough elastomer (rubber) ring that sits within the hammering mechanism to cushion impact loads, reduce vibration, and help maintain smooth, efficient operation. By protecting the striker and related components from shock, it supports consistent performance and extends service life. Ideal for both site and DIY maintenance, it is a direct-fit replacement for selected Makita models, including the HR2230 and HR2460. Replacing a worn or hardened cushion ring can restore impact energy, reduce harshness at the handle, and improve overall drilling and chiselling control. This is a Genuine Makita part made for reliable fit and function.
