Frequently Asked Questions
Q: What are the exact specifications of the SU S9531 load wheel assembly?
A: The SU S9531 is a 2.5 inch diameter by 3.25 inch width load wheel assembly with a machined steel core and high-durability polyurethane tread (92 Shore A hardness). The core is untreated steel and the tread is bonded polyurethane, engineered for electric lift truck performance in fork carriage load positions.
Q: How does the SU S9531 differ from the SU S9531-A, and which one should I order?
A: Both are 2.50 inch by 3.25 inch load wheel assemblies with polyurethane tread on steel cores. The SU S9531 is the standard load wheel for electric lift trucks. The SU S9531-A is designed specifically for compatible select electric walkie vehicles. Verify your equipment type (ride-on truck versus walkie vehicle) before purchase to ensure fitment.
Q: What is the Shore A hardness rating for the SU S9531 polyurethane tread, and what does it mean?
A: The SU S9531 tread has a 92 Shore A hardness rating, which indicates a hard, durable polyurethane compound designed to resist wear under heavy load cycles. This hardness provides good load capacity and tread life but offers less shock absorption than softer compounds. It is suitable for standard electric lift truck loading and material handling applications.
Q: Can I use SU S9531 wheels in steer or caster positions, or only in load positions?
A: The SU S9531 is specifically engineered for fork carriage load positions on electric lift trucks. Do not install in steer or caster positions, as load wheels have different bearing and tread specifications than steer wheels. Using load wheels in steer positions will cause poor handling and accelerated wear.
Q: How do I know when to replace the SU S9531 load wheel?
A: Inspect the tread regularly for wear, cracking, or separation from the steel core. Replace the wheel when tread thickness is reduced to 50 percent of original depth, or if you observe flat spotting, deep cracks, or tread peeling. Worn load wheels reduce load capacity and can damage carriage guides. Replace promptly to maintain safe operation.
Q: What is the proper installation procedure for the SU S9531 load wheel?
A: Remove the old load wheel from the carriage axle by unbolting or removing the axle pin, depending on your truck design. Slide the SU S9531 onto the axle, align it with carriage guides, and secure it with bolts or a new axle pin. Verify the wheel rotates freely and is properly seated in the carriage before returning to service.
