Frequently Asked Questions
Q: What are the equivalent part numbers for the SU 351-A?
A: The SU 351-A is equivalent to SU S351 and SU S351-XL. These part numbers are interchangeable and represent the same 5 inch diameter Cushothane XL load wheel assembly with HeatSink aluminum hub. Cross-reference your existing wheel part number to confirm compatibility before placing an order.
Q: How does the SU 351-A differ from the standard SU 351?
A: The SU 351-A is a heavy-duty upgrade featuring a larger 5 inch diameter compared to the SU 351 is 3.25 inch, uses premium Cushothane XL polyurethane at 97A durometer versus standard 93A, includes a HeatSink vented aluminum hub for thermal dissipation, and has pre-pressed sealed bearings for extended life. The XL3 bonding technology eliminates bond separation failures common in lower-cost wheels.
Q: What is XL3 bonding technology and why does it matter?
A: XL3 is a proprietary adhesive bonding process that mechanically locks the polyurethane to the hub with no risk of separation under load. Standard wheels can experience creep or delamination when the tire pulls away from the hub under stress. XL3 technology eliminates this failure mode and extends wheel life significantly in high-cycle operations.
Q: What electric lift truck types does the SU 351-A fit?
A: The SU 351-A is designed as a universal replacement for standard electric lift truck load wheel assemblies. It is compatible with Crown, Toyota, Raymond, Yale, and similar OEM platforms that use 5 inch diameter load wheels. Verify your truck model and existing wheel bore size before ordering to ensure proper fit and bearing compatibility.
Q: How do I install the SU 351-A on my electric truck?
A: The SU 351-A comes as a complete pre-assembled wheel with sealed bearings. Remove the axle nut and old wheel, slide the new SU 351-A onto the axle, and reinstall the nut hand-tight. Do not over-torque; the wheel should spin freely with no play. Check bearing preload by spinning the wheel and listening for smooth operation. If noise or resistance is present, loosen slightly and re-check.
Q: What load capacity does the SU 351-A support?
A: The SU 351-A supports standard electric lift truck fork load capacity, typically 2,500 to 5,000 pounds depending on your truck model. The 97A Cushothane XL material and vented hub design ensure consistent performance under continuous duty without temperature-related softening. Refer to your truck manufacturer load plate for exact rated capacity.
