Poly Load Wheel 95A
Frequently Asked Questions
Q: What is the difference between SU S0956 and SU S0955?
A: Both SU S0956 and SU S0955 are 95A polyurethane load wheels rated for the same durometer hardness. The primary difference may be in the hub design, mounting style, or bearing configuration. They are often interchangeable, but always verify the part number stamped on your current wheel before ordering. If your truck documentation specifies one over the other, use the specified part number to ensure compatibility and warranty coverage.
Q: Can I install SU S0956 as a direct replacement for SU S0955?
A: In most cases, yes, if the mounting bolt pattern, hub diameter, and bearing type match. Before installing SU S0956, remove one old wheel and compare side-by-side with the new wheel. Check that the mounting studs align, the hub bore diameter is identical, and sealed versus open bearings are the same. If any dimension does not match, do not force installation. Contact your supplier to confirm fitment before proceeding.
Q: What floor types is SU S0956 suitable for?
A: The 95A polyurethane compound in SU S0956 is designed for rough and polished concrete warehouse floors. It provides good durability and traction for general-purpose material handling. On polished concrete or epoxy coatings, the wheel may mark the surface. For sensitive environments such as operating rooms, pharmaceutical cleanrooms, or food processing facilities, verify that SU S0956 is rated non-marking before use. Test on a small area first.
Q: How do I install SU S0956?
A: If SU S0956 is a modular load wheel with separate bearings and axles, carefully remove the old wheel by unbolting the mounting studs. Place the new wheel hub over the axle, ensuring the inner bearing (if installed on the axle) aligns with the hub bore. Push the wheel fully onto the axle until the outer bearing seat contacts the hub. Install the spiral pin or retaining clip to secure the wheel. Torque the mounting bolts to the equipment manufacturer specification. Rotate the wheel by hand; it should spin freely with no grinding noise.
Q: What is the expected service life of SU S0956?
A: Under normal warehouse use, SU S0956 will provide 24-36 months of service before significant wear becomes apparent. The tread will flatten and the sidewalls may show stress cracks after extended use. Inspect every 6-12 months. Replace immediately if you observe flat spots, cuts, cracks, or if the wheel no longer spins freely. Wheels operated at full load continuously or in extremely hot environments may wear faster.
Q: Is SU S0956 sealed or open bearing?
A: The specification does not clearly indicate sealed or open bearings. Check the product documentation or compare with the wheel you are replacing. Sealed bearings require no maintenance and are preferable for wet or contaminated environments. Open bearings must be cleaned and relubricated every 12 months. If replacing an open-bearing wheel with a sealed-bearing model, the mounting hardware may differ; always verify before installation.
