Frequently Asked Questions
Q: What are the specifications of the SU S9138 load wheel assembly?
A: The SU S9138 features a 1.5 inch outer diameter, 2.87 inch tread width, and 1.1 inch precision bearing bore. The tread is high-tensile polyurethane bonded to a machined steel core with no plating. This configuration is typical for fork lift platforms and main load wheels on mid-range lift trucks.
Q: Can I use SU S9138 on a pallet jack or only on electric lift trucks?
A: The SU S9138 is designed primarily for electric lift trucks in high duty-cycle applications. It can be used on manual or semi-electric pallet jacks only if the axle shaft diameter and bearing bore match exactly. Always confirm compatibility with your equipment manual before purchase.
Q: How long does the polyurethane tread typically last?
A: High-tensile polyurethane wheels on the SU S9138 typically last 24 to 48 months in continuous high duty-cycle environments. Lifespan depends on floor surface, ambient temperature, load weight, and storage conditions. Concrete floors wear wheels faster than clean sealed surfaces. Store wheels indoors in dry conditions to slow degradation.
Q: What is the load rating for the SU S9138?
A: Load rating depends on the number and configuration of wheels in the lift truck assembly and is not specified for the individual wheel. Consult your equipment manufacturer for total truck capacity. The steel core and 1.1 inch bearing bore support typical mid-load electric truck applications.
Q: Can the SU S9138 be used in tandem-load configurations?
A: Yes, the SU S9138 can be deployed in tandem configurations where multiple wheels share axle load. The 1.5 inch diameter and high-tensile polyurethane compound are designed to distribute load across paired or quad wheel setups. Verify that all wheels in a tandem pair are the same model and wear state to avoid uneven loading.
