Frequently Asked Questions
Q: What is the difference between nylon wheels (GWK-YA55N-LW) and polyurethane wheels (GWK-YA55-LW)?
A: Nylon wheels (GWK-YA55N-LW) are cast industrial-grade nylon, harder and more durable than polyurethane. Nylon resists cutting and abrasion on rough concrete and outdoor surfaces, lasts longer (18 to 30 months), but offers less traction on smooth floors. Polyurethane (GWK-YA55-LW, 70D) grips better indoors but wears faster (12 to 18 months). Choose nylon for industrial warehouses with rough floors; choose polyurethane for smooth, climate-controlled facilities.
Q: Does GWK-YA55N-LW fit exactly where polyurethane wheels fit on YA55?
A: Yes. GWK-YA55N-LW mounting geometry (bore diameter, axle length, fastener pattern) matches standard YA55 load wheel mounting locations. However, verify wheel dimensions match your current setup before ordering. Nylon wheels have a slightly different rolling resistance than polyurethane, so steering effort may feel marginally different during transition. This is normal and does not indicate misfit.
Q: What maintenance do nylon wheels require compared to polyurethane?
A: Nylon wheels require the same maintenance: grease sealed bearings annually, inspect monthly for debris or damage, and keep wheels clean. Grease fittings are integrated into GWK-YA55N-LW, allowing you to inject grease without disassembly. Replace the entire kit when wheels flatten or crack. Nylon is more forgiving on rough surfaces but still requires routine maintenance to prevent bearing failure.
Q: Can I use GWK-YA55N-LW on outdoor loading docks or only indoors?
A: GWK-YA55N-LW is suitable for outdoor use on loading docks, concrete yards, and rough terrain. Nylon durability withstands weather exposure and abrasive surfaces better than polyurethane. However, avoid prolonged sun exposure that can yellow nylon over time. For outdoor use, inspect wheels quarterly for cracks and bearing grease integrity. Grease fittings allow annual maintenance without full disassembly.
Q: How do sealed ball bearings and integrated grease fittings work together in GWK-YA55N-LW?
A: Sealed bearings contain packing grease and are sealed to prevent contamination. Integrated grease fittings allow you to inject fresh grease annually without opening the bearing housing. Do not over-grease; inject only until grease appears at the seal edge. Over-greasing increases rolling resistance and generates excessive heat. Use lithium or NLGI-2 grease only. Replace bearings as an assembly if seals fail or grinding occurs.
Q: What is the hardened steel axle and why is it important?
A: The hardened steel axle in GWK-YA55N-LW resists bending and wear under heavy load cycles. Soft steel axles deform over time, causing bearing misalignment and failure. Hardened steel maintains true wheel alignment throughout the wheel life span (18 to 30 months). The roll pin fasteners lock the axle securely and prevent rotation. Replace the entire assembly if the axle bends; do not attempt to straighten or repair.
