Frequently Asked Questions
Q: What is the load capacity and recommended operating environment for the SU S850-XL-A wheel assembly?
A: The SU S850-XL-A is a polyurethane load wheel assembly rated for heavy load applications. It is rated for continuous operation in wet and freezer environments. The 6.00 inch outside diameter with 2.75 inch tread width provides load distribution suited for electric lift truck applications. Maximum load capacity depends on total wheel configuration and vehicle design; verify with your truck manufacturer for your specific model.
Q: Is the SU S850-XL-A compatible with my electric lift truck model?
A: The SU S850-XL-A features a 3.14 inch bore diameter with shoulder bearing construction. Verify compatibility by checking your lift truck manufacturer documentation for wheel bore diameter, tread width (2.75 inch), and outside diameter (6.00 inch) specifications. Models from different manufacturers may have different bearing configurations; confirm bearing type and bore specifications before ordering.
Q: What is equivalent to the SU S850-XL-A across other brands?
A: The SU S850-XL-A is a polyurethane wheel assembly with a 6.00 inch OD and 3.14 inch bore. Equivalent products from other manufacturers include Yale and Crown wheels with matching bore diameter and tread width. Always verify the exact part number with your dealer or manufacturer because bore configuration, bearing type, and hub design vary even with similar dimensions.
Q: How do I install the SU S850-XL-A and what tools are required?
A: The SU S850-XL-A is a complete wheel assembly ready for installation. Remove the old wheel by lifting the truck safely on a jack stand and removing the axle bolt. Slide the new assembly onto the axle, ensuring the bore sits fully on the bearing spindle. Reinstall the axle bolt and tighten to the manufacturer torque specification (typically 40-60 foot-pounds). Do not reuse old hardware; use new fasteners to prevent loosening.
Q: What maintenance is required for the SU S850-XL-A wheel assembly?
A: Inspect the polyurethane tread for wear, cracking, or flat spots monthly. Check the shoulder bearing for play or grinding noise by lifting the truck and spinning the wheel by hand. In freezer environments, verify the wheel turns freely because polyurethane can harden in extreme cold. Wipe down the wheel after wet operations to prevent salt buildup. Expected lifespan is 12-24 months depending on usage intensity and environment.
Q: Can the SU S850-XL-A wheel be repaired or refinished?
A: Polyurethane wheels cannot be re-tread or resurfaced. Once the tread is worn to 50 percent of original depth, replacement is required. Damaged bearing assemblies cannot be repaired; the entire wheel must be replaced. Do not attempt to weld or machine the wheel as this damages the polyurethane material and bearing construction. Always order a complete replacement assembly.
