Frequently Asked Questions
Q: What is the difference between SU S151 and SU S153 load wheels?
A: SU S151 is a 5.5 X 5 poly load wheel, while SU S153 is a 5.000 inch diameter by 3.875 inch width Cushothane EZ wheel. The S151 is wider and larger overall. Do not substitute one for the other as bore diameters and fitment are different. Check your equipment manual or existing wheel dimensions before ordering.
Q: Is the SU S151 compatible with Yale and Hyster electric pallet jacks?
A: The SU S151 fits many electric lift truck models, but you must verify the bore diameter and hub width match your equipment. Yale and Hyster use various wheel configurations across their product lines. Cross-reference your jack model number and existing wheel part number before ordering. When in doubt, remove the old wheel and measure the bore diameter and width.
Q: How do I diagnose if my load wheels are worn and need replacement?
A: Signs of wear include flat spots or uneven surfaces on the wheel, loss of steering control or drifting to one side, unusual squeaking or grinding noises during operation, and visible chunks or cracks in the poly material. If the jack pulls to the left or right despite straight steering input, the wheels are likely worn unevenly. Replace both front wheels at the same time to maintain balanced handling.
Q: What is the maximum load capacity of the SU S151 wheel?
A: The SU S151 is designed to support the full rated capacity of your specific electric pallet jack model, typically between 3,000 and 6,000 pounds depending on equipment configuration. Do not exceed the jacks rated capacity. Overloading causes accelerated wheel wear, bearing failure, and steering problems. Check your jack nameplate or manual for exact load limits.
Q: Can I use the SU S151 on wet or oily floors?
A: Yes, the poly material provides good traction in most conditions. However, wet floors with algae or oil require caution. If you operate exclusively on slippery surfaces, confirm the wheel material offers adequate grip for your application. Dirty wheels lose traction quickly, so clean them regularly. If slipping occurs frequently, the wheel material may not be suitable for your environment.
Q: What is the expected lifespan of the SU S151 wheel?
A: Under normal warehouse conditions with proper maintenance, the SU S151 typically lasts 12 to 24 months before replacement. Heavy-use operations, rough floors, or improper alignment reduce lifespan significantly. Inspect wheels monthly for wear. Replace when steering becomes inconsistent, flat spots appear, or chunks develop. Preventive replacement avoids sudden failure in production.
