Retaining Ring

Frequently Asked Questions

Q: What is the 221559 retaining ring used for in manual pallet jacks?
A: The 221559 retaining ring is a circlip or snap ring used to secure components such as wheels, bearings, or shafts in place within manual pallet jack assemblies. The ring sits in a groove and prevents axial movement of parts under load.

Q: What is the bore diameter of the 221559 retaining ring?
A: Retaining ring sizes vary by application. The 221559 is designed for a specific shaft or bore diameter used in manual pallet jack wheel and bearing assemblies. Confirm the exact diameter and groove specifications with your equipment documentation. Using an incorrectly sized ring will not secure the component properly and can cause wheel separation.

Q: What material is the 221559 made from?
A: Retaining rings are typically manufactured from spring steel or stainless steel, selected for resilience and corrosion resistance. The material must maintain sufficient tension to hold components securely over the equipment lifespan while withstanding repeated load cycles.

Q: Can the 221559 retaining ring be reused after removal?
A: Retaining rings are generally not reusable. Removal from the groove weakens the spring tension, and the ring loses its ability to hold components securely. Always install a new ring when disassembling wheel or bearing components. Reusing a weakened ring can result in wheel lockup or separation during operation.

Q: What happens if the 221559 retaining ring is missing or fails?
A: A missing or failed retaining ring allows wheels or bearing assemblies to slide axially on the shaft, causing uneven load distribution, wheel binding, or complete wheel separation. This creates a serious safety hazard and may damage the load wheel or jack frame. Always inspect ring grooves for chips or deformation and replace the ring immediately if compromise is detected.
