Frequently Asked Questions
Q: What is the bore specification for the SU S641-XL?
A: The SU S641-XL features a straight roller bearing with 0.75 inch bore for 3/4 inch axles. The machined steel core is sized to precision tolerances for proper bearing fit without forcing. Do not attempt installation on non-standard axle sizes.
Q: Is the SU S641-XL bearing replaceable?
A: Yes. If the bearing wears but the polyurethane tread is good, the bearing can be pressed out and replaced with a matching straight roller bearing with 0.75 inch bore. However, if both bearing and tread are worn, replace the entire wheel assembly for cost-effectiveness.
Q: How do I install the SU S641-XL on a pallet jack?
A: Remove the retaining clip or cotter pin holding the existing wheel. Slide the old wheel off the axle. Clean the axle of rust or debris with a wire brush. Slide the SU S641-XL onto the axle until it seats. Install a new cotter pin or retaining clip and verify the wheel rotates freely without binding.
Q: Can the SU S641-XL polyurethane be machined or trued?
A: No. The vulcanized polyurethane tread cannot be machined, resurfaced, or trued. Attempting to machine the tread will damage the bond between the polyurethane and the aluminum hub. Replace the entire wheel once the tread wears beyond usable thickness or sustains permanent damage.
Q: What is the wheel diameter and width of the SU S641-XL?
A: The SU S641-XL is 4.000 inch diameter by 2.875 inch width. In metric, this is 101.60mm diameter by 73.02mm width. Verify these dimensions match your truck mounting before ordering. Wrong wheel sizes will not fit the axle assembly.
