Frequently Asked Questions
Q: What are the exact dimensions of SU 854?
A: SU 854 has an outside diameter of 5.000 inches, width of 2.875 inches, inside diameter of 2.25 inches, and tread profile of 3/8 inch radius. In metric, the diameter is 127.00 mm and width is 73.02 mm. The bore outside diameter is 2.4404 inches with a bore depth of 0.817 inches and hub width of 2.875 inches.
Q: Is SU 854 a complete wheel assembly or a wheel core only?
A: SU 854 is a wheel core only, not an assembly. It does not include pre-installed bearings or axle hardware. If you need a complete assembly ready for installation, order SU 854-A, which includes bearings and mounting hardware.
Q: What material is SU 854 made from and why is it used?
A: SU 854 is made from Cushothane XL polyurethane. This compound provides excellent cut and tear resistance, maintains consistent grip on warehouse floors, and resists oils and chemicals common in industrial environments. Cushothane XL is designed for high-duty cycle pallet truck applications.
Q: Can SU 854 be reused from an old wheel assembly or must it be discarded?
A: If the wheel core shows no visible cracks, flat spots, or permanent deformation, you may recondition it by installing new bearings and reinstalling it on a different axle. However, if the polyurethane is worn flat, chunked, or discolored, the wheel must be replaced. Do not reuse wheels with diameter reduction greater than 0.25 inches from original specifications.
Q: What tools and skills are needed to install bearings on SU 854?
A: You will need a bearing press or hydraulic press to seat bearings into the bore. Press bearings to the bore shoulder until the bearing inner race is fully seated. Do not drive bearings with a hammer or improvised tools, as this can damage the bearing races. If you lack a proper press, order SU 854-A which comes pre-assembled.
Q: How do I know if SU 854 is worn out and needs replacement?
A: Measure the wheel diameter at the tread. If diameter has decreased more than 0.25 inches from the original 5.000 inches, or if the tread is worn flat, replace the wheel. Also check for cracks in the polyurethane or gaps between the wheel and hub. A worn wheel will not maintain proper load distribution and increases risk of truck instability.
