Frequently Asked Questions
Q: What is the load rating and Shore A hardness for the SU S675 poly wheel?
A: The SU S675 is a 95A Shore A polyurethane wheel designed for standard electric lift truck caster applications. It provides good traction and wear resistance for light to medium load cycles. Check your truck model documentation to confirm axle diameter and wheel bore compatibility before ordering.
Q: Is the SU S675 a caster wheel or load wheel?
A: The SU S675 is a poly wheel commonly used as a caster or steering wheel assembly. Do not use this for main load-bearing positions on your truck. Use only on steering axles or caster mounts rated for poly wheel mounting.
Q: Can I replace a worn SU S675 without removing the entire axle assembly?
A: Wheel replacement procedure depends on whether your wheel uses a bushing or ball bearing core. If your truck uses a bushing design, you may be able to drive the wheel off the axle stub with the proper puller. Ball bearing wheels require more care to avoid damaging the bearing seals. When in doubt, remove the axle assembly first.
Q: How often should the SU S675 be inspected or replaced?
A: Inspect the SU S675 every six months or every 500 operating hours for visible tread wear, flat spotting, or bearing play. Replace when tread depth is worn to approximately 50 percent of original thickness. Wheels subjected to wet, corrosive, or chemical environments may need replacement sooner.
Q: What is the axle bore diameter for the SU S675?
A: Verify the exact axle bore size and wheel diameter from your truck manual or the wheel specification sheet. Superior offers multiple bore sizes; ordering the wrong size will result in improper fitment. Measure the axle stub or existing wheel before ordering.
Q: Does the SU S675 have sealed or unsealed bearings?
A: Most SU S675 wheels feature sealed deep groove ball bearings to prevent water and debris intrusion. Verify bearing type on your specific wheel by visual inspection. Sealed bearings are maintenance-free; unsealed bearings require occasional greasing.
