4 X 2 POLY LOAD WHEEL
Frequently Asked Questions
Q: What does the -XL designation mean for the SU S9142-XL wheel?
A: The -XL designation indicates enhanced load, cut, and tear resistance compared to standard wheels. SU S9142-XL wheels are constructed with high-grade polyurethane and often feature proprietary bonding technology to withstand demanding duty cycles. Use SU S9142-XL when your operation involves frequent contact with debris, sharp edges, rough floor surfaces, or consistently heavy loads near maximum equipment capacity.
Q: Should I use SU S9142-XL instead of SU S9142-A or SU S9142-EZ?
A: Choose based on your specific operating conditions. SU S9142-A is adequate for standard duty warehouses. SU S9142-EZ is required for wet floors and cold storage. SU S9142-XL is necessary for high-damage-risk environments such as outdoor pavement, construction sites, facilities with sharp metal debris, or operations running near maximum load capacity continuously. Using the heavier-duty wheel in low-stress applications wastes money. Upgrading to SU S9142-XL when needed prevents mid-shift wheel failures and downtime.
Q: How long do SU S9142-XL wheels last compared to standard wheels?
A: In high-demand environments, SU S9142-XL wheels typically provide 30 to 50 percent longer service life than standard wheels because of their superior cut and tear resistance. In moderate-duty applications, the extended lifespan advantage is minimal. Expected life ranges from 2000 to 4000 operating hours depending on load weight, floor surface, and debris frequency. Track actual replacement intervals in your operation to compare total cost of ownership.
Q: What is the installation procedure for SU S9142-XL?
A: Installation is identical to standard wheels. Remove the axle bolt or cotter pin holding the old wheel in place. Slide the wheel assembly off the axle. Check the axle for dirt, corrosion, or damage and clean if needed. Slide the SU S9142-XL assembly onto the axle. Reinstall the axle bolt and tighten firmly, or secure with a new cotter pin if applicable. Verify the wheel spins freely without binding before returning the equipment to service.
Q: Are SU S9142-XL wheels compatible with my current pallet jack?
A: SU S9142-XL is a 4 x 2 wheel assembly designed to replace standard 4 x 2 assemblies with the same bore diameter and axle type. Check your equipment nameplate or manual for the original wheel specifications. If your equipment originally used different wheel dimensions or a unique mounting system, the SU S9142-XL will not fit. Measure the axle bore diameter on your jack and compare to the SU S9142-XL specification sheet before ordering.
Q: What preventive maintenance extends the life of SU S9142-XL wheels?
A: Inspect wheels weekly in high-damage environments for embedded debris, cuts, or flat spots. Remove any sharp objects lodged in the tread immediately. Check bearing play every 200 hours and apply grease if the assembly uses grease-packed bearings. Inspect wheel-to-frame clearance to ensure no rubbing occurs. Clean road salt residue with fresh water in winter operations to prevent hub corrosion. These practices maximize the durability advantage of the heavy-duty XL design.
