Frequently Asked Questions
Q: What is the difference between SU 850-XL-A and standard polyurethane wheel assemblies?
A: SU 850-XL-A is constructed with Cushothane XL compound and XL3 mechanical/chemical bonding technology, which provides superior resistance to cut and tear compared to standard wheels. The pre-assembled bearings eliminate field assembly, reducing installation time and compatibility issues on high-duty cycle electric lift trucks.
Q: Can SU 850-XL-A be used as a direct replacement for older wheel assemblies on electric lift trucks?
A: SU 850-XL-A is compatible with most electric lift truck models, but verify the mounting bore diameter, axle configuration, and load capacity rating of your specific truck before installation. Contact the truck manufacturer or your parts supplier with the truck model and serial number to confirm fitment.
Q: What maintenance is required for the pre-assembled bearings on SU 850-XL-A?
A: The pre-assembled bearings are sealed and require no lubrication in normal operation. Inspect bearings visually every 250 operating hours for grinding noise, lateral play, or visible damage. If bearing noise develops or the wheel does not spin freely by hand when lifted, replace the assembly; do not attempt to repack or repair sealed bearings.
Q: What is the load rating and recommended duty cycle for SU 850-XL-A?
A: SU 850-XL-A is rated for high-duty cycle pallet truck operations. Load capacity and maximum RPM depend on truck model and configuration. Verify the truck nameplate or service manual for load ratings. Exceeding rated load or RPM will accelerate wear of the polyurethane compound and void warranty coverage.
Q: How long does SU 850-XL-A typically last in service?
A: Lifespan depends on load weight, floor surface, and hours of operation. In typical warehouse use, expect 12 to 24 months before polyurethane wear becomes noticeable. High-duty operations may require replacement within 6 to 12 months. Replace when tread depth falls below 1/4 inch or when wheel diameter visibly decreases.
Q: Is SU 850-XL-A equivalent to any other manufacturer part numbers?
A: SU 850-XL-A is a proprietary part number for electric lift truck wheel assemblies. Cross-references may exist with other suppliers, but confirm dimension, material, bore configuration, and bearing type before substituting. Contact your distributor with the truck model to identify compatible alternatives.
