Product Description
This complete wheel kit provides two Ultra-Poly (70D) load wheel assemblies and two Poly steer wheel assemblies, ensuring high-quality performance with included bearings, axles, and fasteners for straightforward installation. The Ultra-Poly load wheels offer enhanced durability and smooth rolling, while the non-marking design protects delicate flooring surfaces. Designed for optimal performance on various surfaces, these wheels cater to multiple applications in warehouses and cold storage environments.

Frequently Asked Questions
Q: What is the difference between the complete kit GWK-ELP55-CK and load-wheel-only kits?
A: GWK-ELP55-CK is a complete kit that includes two 70D Ultra-Poly load wheel assemblies AND two Poly steer wheel assemblies. Load wheels bear the cargo weight and require harder material (70D durometer). Steer wheels guide direction and can use softer, lower-durometer material. If only load wheels are worn, you can order the load-wheel-only kit to save cost. Always replace both wheels on the same axle together to prevent uneven handling.
Q: Is GWK-ELP55-CK compatible with other Mobile pallet jack models?
A: GWK-ELP55-CK is engineered for the Mobile ELP55 model only. Cross-fitment to models such as ELP45, ELP65, or competitor brands (Multiton, Yale) is not recommended without verifying axle diameter, bearing bore, and wheel mounting specifications. Always reference your pallet jack serial number and consult the OEM parts list before ordering.
Q: Can I replace only the load wheels and reuse the steer wheels?
A: Yes, if the steer wheels are in good condition. However, if you are replacing the kit, inspect steer wheels for flat spots, cracking, or bearing play. Mixing old steer wheels with new load wheels can cause handling instability and uneven wear. For simplicity and safety, replace the complete set when any wheel shows significant wear.
Q: What does non-marking mean, and which surfaces is GWK-ELP55-CK suitable for?
A: Non-marking means the wheel does not scuff, streak, or discolor polished floors, tile, or epoxy surfaces. 70D Ultra-Poly compound is soft enough to conform to delicate floors but hard enough to resist deformation under load. This kit is ideal for retail showrooms, hospitals, clean rooms, and warehouses with sealed flooring. Do not use on rough concrete or outdoor surfaces with rocks; the wheels will embed debris and become damaging.
Q: How do I diagnose if the load wheels or steer wheels are failing?
A: Load wheel failure signs: the jack pulls to one side, the tiller arm requires excessive steering effort, or you hear grinding/squeaking. Flat spots or visible cracks mean immediate replacement. Steer wheel failure signs: the jack does not track straight, wheels do not return to center, or the steer wheel is locked/does not spin. Lift the truck and manually spin each wheel; resistance or wobbling indicates bearing wear. Replace the wheel assembly; do not repack bearings.
Q: What maintenance is required for the GWK-ELP55-CK wheels and bearings?
A: These wheels feature sealed roller bearings; no repacking or greasing is required under normal service. Every 500 hours of operation, inspect wheels for debris embedding and wipe clean. Check bearing seals for cracks or leakage. If bearing is damaged or leaking, the entire wheel assembly must be replaced; sealed bearings cannot be serviced in the field. Store wheels indoors in a dry area to prevent rust on the axle.
