Locking Ring for Hyster Bearings

Frequently Asked Questions

Q: What is the purpose of the HY 4095579 locking ring on a pallet jack or lift truck?
A: The locking ring is a retaining component that secures a wheel or bearing cartridge onto an axle shaft or in a housing bore. It prevents axial movement and keeps the wheel, bearing, or other assembly from sliding off under load.

Q: Which Hyster equipment models and axle types use the HY 4095579 locking ring?
A: The HY 4095579 locking ring is designed for specific Hyster steer wheel, load wheel, or bearing assemblies. Verify your equipment model, axle shaft diameter, and bearing bore dimensions against the Hyster parts catalog to confirm this ring is correct for your application.

Q: What material is the HY 4095579 locking ring made from?
A: This locking ring is manufactured from hardened steel, typically with a snap-fit or threaded design depending on the axle configuration. The material is engineered to resist deformation and maintain secure retention under dynamic load.

Q: How do I know if the HY 4095579 locking ring is worn or damaged?
A: Inspect the locking ring for cracks, bending, or permanent deformation. If the wheel spins freely on the axle or moves side-to-side, the locking ring may be loose or damaged. A compromised locking ring can allow the wheel to separate from the axle, creating a safety hazard.

Q: Can the HY 4095579 locking ring be used on different wheel or axle sizes?
A: No. The locking ring bore diameter, snap fit groove, or thread pitch must match the axle shaft diameter or bearing bore precisely. Using an incorrect ring size will not secure the component and can cause wheel slippage or bearing failure. Always verify dimensions match your axle and wheel assembly.
