Applicable Scenarios

Used inside the feeding transmission assembly of XCMG RP705 paver to lock the bearing on the shaft. Widely used in asphalt paving projects including municipal roads, expressways, factory pavements and airport runways.

▪ Standard OEM dimension, fits φ140 mm shaft groove tightly with 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 assembly and disassembly
▪ Works with bearings and spacers for combined limiting, shares axial load and reduces pressure on other limit parts
▪ Compact for easy spare storage and low replacement cost

FAQ

Q: Can the retaining ring be reused after expansion for disassembly?
A: Repeated expansion and reuse are not recommended. Multiple stretching weakens elasticity and raises the risk of popping out under continuous vibration; replacement is preferred during overhaul.

Q: Can this retaining ring withstand heavy axial impact?
A: It serves only as a limiting part and is not designed for heavy impact. Large axial impact loads should be carried jointly by spacers and retaining plates.

Q: What tool is recommended for installation?
A: Shaft retaining ring pliers are preferred. Prying is forbidden to avoid distortion and permanent elastic damage.

Q: What faults may be caused if the retaining ring falls off?
A: The bearing loses axial restraint with increased clearance and abnormal noise. In serious cases, the bearing shifts and seizes, shutting down the feeding transmission.
