External Circlip Self-Locking Retaining Clip Push-On Shaft Bearing Snap Ring — 65Mn Steel & 304 Stainless Steel M2–M12
Self-locking push-on external circlips (speed nuts / push-on retaining rings) for shaft retention without a machined groove. Simply push onto the shaft — the internal teeth grip the shaft surface and lock in place. No groove machining required, making these ideal for rapid assembly, prototyping, and applications where groove machining is impractical. Available in 65Mn spring steel and 304 stainless steel.

- Tool-free installation — push on by hand; no circlip pliers needed
- Internal teeth locking — teeth grip shaft surface for secure retention
- Two material options — 65Mn steel for maximum grip; 304 SS for corrosion resistance
- M2–M12 range — covers miniature electronics to medium machinery shafts
Typical Applications
- Rapid prototyping shaft retention (no groove machining)
- RC model and drone motor shaft retention
- 3D printer motor and idler shaft retention
- Light-duty bearing and gear retention on smooth shafts
- Consumer electronics shaft and pin retention
FAQ
Q: Can push-on circlips be removed?
A: Push-on circlips can be removed with flat-nose pliers, but they are typically single-use as removal may deform the internal teeth. For reusable retention, use E-clips or C-type circlips with a machined groove.
Q: What axial load can push-on circlips handle?
A: Push-on circlips are designed for light to medium axial loads. For heavy axial loads, use C-type circlips (DIN471) with a machined shaft groove for maximum retention force.
