Frequently Asked Questions
Q: What is the difference between SU S9141-A and SU S9141?
A: The SU S9141-A is a complete wheel assembly that includes sealed bearings and lube fittings pre-installed. The base SU S9141 is the wheel core only. The -A designation means you receive the entire ready-to-install assembly, reducing on-site assembly time.
Q: What are the equivalent part numbers for SU S9141-A?
A: The SU S9141-A is equivalent to SUS9141, S9141XL, and SU9141XL. It supersedes older standard S9141 assemblies. Always cross-reference against your equipment nameplate or OEM parts diagram to confirm equivalence before ordering.
Q: Are sealed bearings included in the SU S9141-A assembly?
A: Yes. The SU S9141-A comes with sealed roller or ball bearings pre-installed and factory-sealed. Sealed bearings reduce maintenance intervals and improve protection against water and dust ingress in harsh warehouse or cold storage environments.
Q: How often should I lubricate the bearings on SU S9141-A?
A: Sealed bearings are factory-lubricated and require minimal maintenance. Use lube fittings only if your equipment manual specifies a greasing interval, typically every 500 to 1000 operating hours. Over-greasing can damage seals and cause bearing failure.
Q: Can I replace just the polyurethane tread on a worn SU S9141-A, or must I replace the entire assembly?
A: In most cases, the entire assembly must be replaced. The polyurethane tread is bonded to a machined steel core, and separation or reworking is not practical in field conditions. Order a new SU S9141-A assembly and remove the old one completely.
Q: What polyurethane specification does the SU S9141-A use?
A: The SU S9141-A features 95A Shore hardness polyurethane, compound Cushothane-series formulation, bonded to a machined steel core. This provides good traction, moderate shock absorption, and resistance to wear in general material handling applications.
