Frequently Asked Questions
Q: Q: What is the hardness rating for GWK-PTH-LW wheels, and how does 70D compare to other durometers?
A: GWK-PTH-LW wheels are 70D Shore A durometer ultra-polyurethane. This hardness rating means the wheels are moderately rigid yet provide slight flex to absorb impact and protect floors from damage. Lower durometers (60D or below) are softer and wear faster on rough concrete. Higher durometers (80D or above) are harder but transfer more shock to the jack frame and can damage sensitive flooring. 70D is the OEM standard for warehouse environments balancing durability, floor protection, and maneuverability.
Q: Can I use GWK-PTH-LW on outdoor concrete or rough floors?
A: GWK-PTH-LW can be used on outdoor concrete, but wheel wear will increase 40 to 60 percent faster than indoor use because rough surfaces increase friction and abrasion. If your warehouse has both smooth and rough areas, expect wheel replacement every 12 to 15 months instead of 18 to 24. Zinc-plated axles resist corrosion in outdoor humidity but inspect for rust at the wheel bore monthly.
Q: Are GWK-PTH-LW bearings pre-lubricated or do they need greasing?
A: GWK-PTH-LW bearings are precision-sealed and come pre-lubricated with a synthetic oil. No manual greasing is required. The sealed design prevents water and dirt from entering while retaining the factory lubrication throughout the bearing life. Attempting to add grease to sealed bearings can actually damage the seals and shorten bearing life. Replace the wheel assembly if bearing noise or drag develops.
Q: Do GWK-PTH-LW wheels come assembled on the axles or as loose components?
A: GWK-PTH-LW wheels, bearings, and axles ship as pre-assembled load roller units ready to bolt onto your pallet jack. The snap rings and fasteners are included separately. Installation involves removing your old axle assembly, sliding the new GWK-PTH-LW load roller onto the jack frame mounting bracket, aligning the mounting holes, and tightening the fasteners. Most technicians complete installation in 20 to 30 minutes per wheel.
