Frequently Asked Questions
Q: What is the durometer rating of the SU S258-XL-A polyurethane wheel, and why does it matter?
A: The SU S258-XL-A features a 97A Shore durometer polyurethane compound. This hardness rating means the wheel resists deformation under heavy loads and extended cycle times. Higher durometer wheels wear slower and handle sustained pallet truck duty better than lower-hardness alternatives like 95A wheels, making the S258-XL-A ideal for high-volume material handling environments.
Q: Can I use the SU S258-XL-A wheel assembly as a direct replacement for SU S260 or SU S262 wheels?
A: No. The SU S258-XL-A is a complete load wheel assembly with a corrosion-resistant steel hub and high-capacity bearing, while SU S260 and SU S262 are individual load wheel components with different durometer ratings and core specifications. Verify your truck model documentation to confirm which assembly type your electric lift truck requires before ordering. Do not force incompatible assemblies onto the axle—bearing misalignment will cause premature failure.
Q: What bearing type does the SU S258-XL-A assembly use, and what load capacity should I expect?
A: The SU S258-XL-A includes a high-capacity bearing. The bearing is rated for heavy-duty pallet truck cycles. Do not exceed the load rating specified in your truck manufacturer documentation. Overloading the assembly will accelerate bearing wear and damage the steel hub. If you are unsure of your truck load rating, contact the manufacturer or consult the nameplate on your electric lift truck.
Q: How do I know if the SU S258-XL-A bearing needs replacement?
A: Signs of bearing failure include grinding noise during wheel rotation, lateral play in the wheel (side-to-side movement), or difficulty steering the truck. Spin the wheel by hand with the truck lifted. If the wheel does not rotate freely or feels rough, the bearing is worn. Replace the entire assembly rather than attempting to repack or repair the bearing. Bearing replacement requires bearing pullers and proper axle removal tools.
Q: Does the corrosion-resistant steel hub require maintenance?
A: The corrosion-resistant steel hub resists rust and oxidation better than bare steel, but does not require special maintenance. Rinse the wheel assembly with clean water after exposure to salt water or corrosive chemicals. Do not use abrasive cleaning methods that damage the protective coating. Inspect the hub quarterly for surface pitting or discoloration indicating corrosion breakthrough, and replace the assembly if corrosion penetrates the hub wall.
Q: What is the expected service life of the SU S258-XL-A assembly?
A: Under normal heavy-duty use, the polyurethane tread lasts 12 to 24 months before wearing flat. The bearing typically outlasts the polyurethane if the assembly is not overloaded or run on rough surfaces. Worn polyurethane reduces traction and increases steering effort. Replace the entire assembly when the tread depth becomes visibly thin or the wheel does not grip the floor during turns. Do not attempt to resurface or recycle worn assemblies.
