Frequently Asked Questions
Q: What is the durometer rating for the SU 629 and how does it compare to XL grade wheels?
A: The SU 629 is 95A Shore A hardness, which is slightly softer than XL grade wheels (97A hardness). The 95A rating provides superior durability and performance for pallet jack applications with moderate to heavy loads. If your equipment specifies 97A hardness, use the SU 627-XL or SU 628-XL instead. Do not substitute hardness ratings as this affects load capacity.
Q: Is the SU 629 equivalent to the SU 629-A?
A: The SU 629 is a single wheel while SU 629-A is a wheel assembly. Both have the same 3.25 x 5.937 inch dimensions, but SU 629-A comes pre-assembled with the hub. If your lift truck is set up for single wheels, order SU 629. If it requires a complete assembly, order SU 629-A. Using the wrong configuration may require custom machining.
Q: What core material is used in the SU 629?
A: The SU 629 has a steel core with mill finish (raw steel finish). The mill finish provides the correct surface texture for polyurethane bonding. If the core shows rust or corrosion, the wheel must be replaced as the rust compromises the bond integrity between the tread and hub.
Q: What are the installation dimensions for the SU 629?
A: The SU 629 has a 1.938 inch inside diameter, 1.18 inch bore depth, and 5.937 inch hub width. Verify these measurements match your lift truck axle before installation. A bore depth of 1.18 inch is deeper than some other models, so confirm your equipment compatibility by checking the existing wheel bore.
Q: When should the SU 629 be replaced?
A: Replace the SU 629 if tread wear exceeds 1/8 inch depth, visible cracks appear, the wheel is flat spotted, or if the polyurethane has separated from the steel core. Check quarterly for these conditions. Worn wheels reduce load capacity and create uneven rolling that damages the axle bearings.
