Frequently Asked Questions
Q: What is the GWK-HY55N-CK and what makes it different from standard polyurethane wheel kits?
A: The GWK-HY55N-CK is a complete nylon wheel kit for Hyster HY55 manual pallet jacks. Unlike polyurethane wheel kits, nylon wheels are non-marking, silent, and perform better in cold storage and sensitive floor environments such as food production and pharmaceutical facilities.
Q: Is GWK-HY55N-CK a direct replacement for GWK-HY55-CK?
A: Dimensionally yes, both fit Hyster HY55 jacks and bolt on identically. However, they are functionally different: GWK-HY55N-CK includes nylon wheels while GWK-HY55-CK includes polyurethane wheels. Do not mix wheel types on the same jack as this changes load and steering characteristics.
Q: What cross-reference part numbers are equivalent to GWK-HY55N-CK?
A: Cross-reference numbers include GWK-HY55-CK, GWK-HY55N-LW, and GWK-HY55-LW. However, verify the exact wheel material specification before substituting, as not all cross-reference numbers use identical wheel construction.
Q: What temperature range are nylon wheels rated for?
A: Nylon wheels operate from -20°F to +140°F. Below -20°F, nylon becomes brittle and may crack under load. Above +140°F, nylon softens and loses shape. This makes nylon ideal for cold storage but not suitable for outdoor or high-temperature loading environments.
Q: Are nylon wheels safe for polished and sealed concrete floors?
A: Yes. Nylon is non-marking and safe for polished concrete, epoxy-coated floors, and sealed surfaces. This is a primary advantage over polyurethane wheels, which can leave marks under load or friction.
Q: Are the bearings and axles in GWK-HY55N-CK different from polyurethane wheel kits?
A: No. Both kits use sealed chrome steel bearings and hardened steel axles. The difference is only in the wheel core material. Service factors and bearing specifications are identical for both kits.
Q: What routine maintenance is recommended for nylon wheel assemblies?
A: Inspect wheels periodically for cracks or deformation, especially if operating near the temperature limits. Check bearing seals for damage and ensure fasteners remain tight. Nylon wheels require no special lubricants or coatings; standard cleaning with mild soap and water is sufficient.
