Applicable Scenarios

Used in left and right feeding drive shaft assemblies of XCMG RP705 paver to lock bearings and matching spacers on the shaft. Widely used in asphalt paving projects including municipal roads, expressways, factory pavements and airport runways.

▪ Standard OEM specification for φ90 mm shaft groove with tight fit and excellent interchangeability
▪ Heat-treated spring steel delivers stable elasticity and good fatigue resistance under repeated load
▪ Uniform cross-section with reliable expanding and contracting performance for easy installation and removal
▪ Cooperates with bearings and spacers to share axial load and reduce burden on other limit parts
▪ Compact size for convenient stocking and low replacement cost

FAQ

Q: Can the retaining ring stay in use if slightly deformed after expansion during installation?
A: Shaft retaining rings are not recommended for repeated expansion. If warped or weakened in elasticity, even if clipped into groove temporarily, it may pop out under vibration. Replacement is advised.

Q: Can this retaining ring bear heavy axial impact?
A: It is a limiting part rather than a heavy-load bearing part. It prevents shifting; large axial impact should be carried jointly by spacers and retaining plates.

Q: Is special tool required for installation?
A: Shaft retaining ring pliers are recommended to avoid distortion and permanent elastic damage caused by prying.

Q: What failures will happen if the retaining ring comes off?
A: The bearing loses axial restraint with increased clearance and abnormal noise. In severe cases, the bearing shifts and seizes, shutting down the feeding system.
