Frequently Asked Questions
Q: What are the exact dimensions and bore specifications for the SU S9135 load wheel?
A: The SU S9135 is 3.25 inches in outer diameter by 5 inches in width. It has a 20mm bore with a cast iron hub and an inside diameter of 1.938 inches. The polyurethane tread is industrial grade at 95A durometer. The 20mm bore requires a matching spindle diameter on your electric lift truck.
Q: Can the SU S9135 replace wheels on Crown, Toyota, or Raymond electric pallet jacks?
A: The SU S9135 may fit Crown, Toyota, Raymond, and other OEM electric pallet jacks if they have a 20mm spindle diameter and accept a 3.25 by 5 inch wheel size. No direct cross-reference part numbers are available. Verify your equipment specifications and spindle diameter before ordering. Contact the equipment manufacturer if unsure.
Q: What is the load capacity and weight limit for the SU S9135 wheel?
A: Load capacity depends on the jack model, not the wheel alone. The SU S9135 is designed for standard electric pallet jack duty cycles. The cast iron hub and industrial-grade polyurethane tread support typical warehouse operations. Do not exceed the weight rating of your specific jack model, as the wheel is only one component in the load path.
Q: How do I diagnose if my SU S9135 wheel needs replacement?
A: Replace the wheel if you observe flat spots, cracks, or chunks missing from the tread; excessive side play or wobbling when spinning the wheel; grinding or squeaking noises during operation; or visible wear that reduces the tread depth below 50 percent. Test by manually pushing the jack and feeling for resistance or pulling side to side at the wheel to check bearing play.
Q: Is the SU S9135 interchangeable with the SU S9135-A or SU S9135-EZ?
A: The SU S9135, S9135-A, and S9135-EZ are similar in outer dimensions (3.25 by 5 inches) and bore size (20mm for S9135, but verify S9135-A and S9135-EZ specs). However, hub material and construction differ. Use only the exact Superior part number specified for your jack to ensure compatibility. Mixing similar wheels from different product lines may cause fitment or safety issues.
Q: Does the SU S9135 require bearing maintenance or grease?
A: The SU S9135 wheel assembly is sealed and does not require periodic greasing or bearing maintenance. Do not attempt to disassemble or repack the bearing. If bearing noise develops or the wheel becomes difficult to spin, the entire wheel assembly must be replaced. Bearing failure is not field-serviceable.
