CAST LOAD WHEEL
Frequently Asked Questions
Q: What is the difference between the SU S940 cast load wheel and a rubber or polyurethane wheel?
A: The SU S940 is a cast iron or steel load wheel with a hard, rigid surface. Cast load wheels are used in the front drive axle position on pallet jacks and are designed to handle high radial loads. Unlike softer rubber or polyurethane wheels, cast wheels provide less traction and are louder on concrete. They excel at load support and are less prone to wear from cutting or chemical exposure.
Q: Can the SU S940 be used interchangeably with traction wheels on a pallet jack?
A: No. The SU S940 cast load wheel is not interchangeable with softer traction wheels. Load wheels must remain in the front drive axle. Traction wheels belong in the rear caster position. Swapping them will cause poor steering, reduced traction, and accelerated bearing failure. Always install cast load wheels in the OEM-specified position.
Q: Is the SU S940 compatible with Crown, Yale, and Raymond pallet jacks?
A: The SU S940 is equivalent to load wheels used across Crown, Yale, Raymond, and similar electric and manual pallet jacks, provided the wheel diameter, axle bore, and mounting configuration match. Verify your OEM part number before ordering. Many models within a single brand may use different wheel sizes, so confirm serial range or model designation.
Q: How do I know when the SU S940 load wheel needs replacement?
A: Replace the SU S940 if you observe visible cracks in the cast surface, chunks missing from the wheel rim, flat spots, or severe scoring. Listen for grinding or unusual noise from the front of the jack during operation. If the jack pulls to one side or feels unstable under load, a damaged load wheel may be the cause. Stop use immediately if the wheel is compromised, as it can cause loss of control.
Q: Can the SU S940 be repaired or resurfaced, or must it be replaced?
A: Cast load wheels cannot be safely resurfaced or repaired. Once cracked or damaged, they must be replaced. Attempting to weld or machine repair a cast wheel introduces stress points and creates a safety hazard. Always replace the entire wheel assembly. Repair attempts can fail under load and cause accidents.
Q: What load-carrying capacity does the SU S940 support?
A: The SU S940 is designed to support the full load capacity of the pallet jack on which it is installed, typically ranging from 2000 to 6000 pounds depending on the jack model. Verify the load rating of your specific jack by serial number. Exceeding the rated load causes premature bearing wear and accelerates damage to the load wheel.
