Frequently Asked Questions
Q: What wheel material and hardness does the GWK-UL-LW use?
A: The GWK-UL-LW features Ultra-Polyurethane (70 Shore D) load wheels precision-molded for durability. The 70D hardness provides a balance between load-bearing capacity and floor protection, making it suitable for heavy warehouse use on smooth concrete floors.
Q: Which pallet jack models does this load wheel kit fit?
A: The GWK-UL-LW is designed for Ultra UL 5500 pallet jacks and compatible Lift-Rite models including LCU and LCU4W. Verify your jack model before ordering to ensure proper fitment. The wheel diameter is 80 mm with a 70 mm tread width.
Q: What is the maximum load capacity with GWK-UL-LW wheels installed?
A: The GWK-UL-LW load wheels are rated for a maximum load of 5500 lbs. This is the same capacity as the original Ultra UL 5500 jack. Never exceed this weight limit; doing so will damage the wheels, bearings, and axles.
Q: Are the bearings pre-installed and sealed, or do they need assembly?
A: The GWK-UL-LW comes with high-performance sealed ball bearings that are pre-installed in the wheels. The bearings are sealed against moisture and dust, so no lubrication or maintenance is required during normal operation. Simply install the wheels with axles and fasteners.
Q: What are the specifications for the axles and fasteners?
A: The GWK-UL-LW kit includes hardened steel axles designed for heavy load applications. All fasteners are precision lock nuts that resist loosening under vibration. Torque lock nuts firmly to prevent wheel wobble, but do not over-tighten as this will bind the bearings.
Q: How does the 70D hardness compare to other polyurethane wheel options?
A: The 70D hardness is softer than 95A wheels but harder than 60D wheels. 70D wheels offer lower rolling resistance, smoother operation, and better floor protection than higher hardness options. They are ideal for manual pallet jacks used on smooth concrete floors in distribution centers.
