Frequently Asked Questions
Q: What are the cross-reference part numbers for the SU S9812-XL-A?
A: The SU S9812-XL-A is equivalent to Superior Tire and Rubber V500878, Crown V509150, Raymond 632-052, and Hyster V500458. These part numbers reference the same 3.25 inch by 6.01 inch load wheel assembly with Cushothane XL polyurethane compound and aluminum hub. Always verify your lift truck OEM designation and current wheel part number before substituting equivalents.
Q: What is the HeatSink aluminum hub feature on the SU S9812-XL-A?
A: The HeatSink aluminum hub is designed to dissipate bearing friction heat away from the wheel bond line, extending wheel assembly life in high duty cycle applications. Aluminum naturally conducts heat better than steel, reducing thermal stress on the polyurethane to hub bond. This technology is especially beneficial in continuous operation environments where sustained wheel friction generates significant heat.
Q: Does the SU S9812-XL-A come with the XL3 Bonding technology?
A: Yes. The SU S9812-XL-A uses XL3 Bonding technology with no bond separation guarantee. This advanced adhesive and mechanical bonding process creates a permanent wheel-to-hub connection that resists separation under load cycling and thermal stress. The no bond separation guarantee means the wheel will not delaminate from the hub during normal use within the rated load capacity.
Q: Is the SU S9812-XL-A compatible with Crown, Raymond, and Hyster lift trucks?
A: The SU S9812-XL-A is compatible with Crown, Raymond, and Hyster lift truck models that originally came with a 3.25 inch by 6.01 inch load wheel assembly. The cross-reference part numbers confirm compatibility with these OEM systems. However, spindle shaft designs and bore specifications can vary by model year and series. Always verify your current wheel specifications match the SU S9812-XL-A before ordering.
Q: What does Cushothane XL 97A polyurethane mean?
A: Cushothane XL refers to a proprietary polyurethane compound engineered for extended wear life. The 97A designation indicates Shore A durometer hardness at 97, which provides the balance between load support and grip. Higher durometer equals harder compound and longer wear life. The 97A hardness is optimized for electric lift truck load wheels operating in standard warehouse conditions.
Q: How is the SU S9812-XL-A shipped and what is the lead time?
A: Contact our parts department directly for current stock status and lead times. The SU S9812-XL-A ships complete and ready to install. Order quantities depend on your replacement schedule and lift truck fleet size. We stock these assemblies to support quick turnaround on urgent replacements. Provide your lift truck model and serial number when ordering to ensure correct fitment.
