- Compact size effectively avoids mechanical damage caused by parts coming out of the body.

FAQ

Q: Why does the retaining ring pop out frequently?
A: Usually caused by shallow worn shaft grooves, fatigue loss of spring force or heavy mechanical impact. Inspect the shaft groove.

Q: Is a rusty retaining ring usable?
A: Light surface rust is acceptable without section thinning or cracks. Replace heavily corroded rings.

Q: Can a close-size retaining ring replace this φ30 ring?
A: Not recommended. Mismatched size leads to locking failure and high risk of falling off.

Q: What failures will be caused if the retaining ring fails?
A: Bushings and bearings lose axial restraint, hinge clearance increases, and components may fall off and jam the mechanism.
