Genuine Makita retaining ring — part no. 961052-5. External circlip (S‑12) designed to locate and lock components on a shaft groove.
Key details:
- Type: external retaining ring / circlip (DIN 471 style), size S‑12 — (12 mm shaft). Typical DIN 471 S‑12 dimensions are around 11.0 mm inner diameter (d3) with a cross‑section ≈1.0 mm.
- Condition: genuine Makita spare part, supplied as the single retaining ring (qty 1 as shown in Makita parts breakdowns).
- Function: secures bearings, gears, collars or other components on a shaft groove; installs with external circlip pliers into the shaft groove to restore proper axial retention.
Example models where Makita lists this part in the parts breakdown or compatibility listings (examples only): Makita 9565 angle grinder; belt sanders such as 9401/9402 and related models; 9555NB; UC120DWAE; drill and grinder models shown in Makita parts cross‑references (for example listings including 9218PBL, DA3010F and 4100KB / 3901).
Why this part matters: the correct S‑12 circlip seats in the factory groove to hold rotating or sliding parts axially — replacing a worn, stretched or missing clip with the original Makita part restores the tool’s designed retention and alignment.
(Install note: use appropriate external circlip pliers and verify the clip seats fully in the groove before returning the tool to service.)
