POLY LOAD WHEEL,95A
Frequently Asked Questions
Q: What is the hardness rating of the SU S157 poly load wheel?
A: The SU S157 is rated at 95A durometer. This is a medium-hardness polyurethane compound suitable for general material handling on smooth to moderately textured floors. The 95A rating provides good balance between load capacity and floor protection.
Q: Is the SU S157 wheel pre-assembled with bearing and axle?
A: The SU S157 is a wheel only, not a complete assembly. It does not come with bearing or axle. You will need to source and install the bearing and axle separately if replacing a wheel assembly.
Q: What is the difference between SU S157 and SU S157-A?
A: The SU S157 is the wheel component only. The SU S157-A is the complete assembly, which includes the wheel, bearing, and axle pre-installed and ready to mount. Choose the SU S157-A if you need a plug-and-play replacement; choose SU S157 if you only need the wheel.
Q: Can I install the SU S157 wheel on an existing axle and bearing?
A: Yes. If your existing bearing and axle are in good condition, you can remove the old wheel and press the SU S157 wheel onto the same axle. Inspect the axle for wear, corrosion, or damage before reuse. If the axle or bearing is worn, replace with a complete assembly like the SU S157-A.
Q: How do I know when the SU S157 wheel needs replacement?
A: Replace the SU S157 wheel if you observe flat spots, cracks, severe chunking, or uneven wear; if the wheel does not roll smoothly or causes vibration; or if the tread is worn smooth. A worn wheel reduces load stability and increases floor marking. Check wheels during routine maintenance every 500 operating hours.
