POLY LOAD WHEEL,95A
Frequently Asked Questions
Q: What does 95A mean on the SU S9116 polyurethane wheel?
A: 95A refers to the durometer hardness rating on the Shore A scale. At 95A, SU S9116 is a medium-firm polyurethane offering balanced grip and load distribution. It resists abrasion better than softer wheels but provides less shock absorption. This hardness is typical for load wheels on electric pallet trucks operating on hard warehouse floors.
Q: Can SU S9116 be used as a replacement for aisle guide wheels?
A: No. SU S9116 is a load wheel designed to carry load vertically, not to guide lateral movement like SU S9112 or SU S9112-A. Using SU S9116 in a guide application will cause improper tracking, accelerated wear, and misalignment. Always use guide-specific wheels for aisle guidance.
Q: What is the load capacity of SU S9116?
A: SU S9116 load capacity depends on wheel diameter, bore diameter, bearing type, and quantity of wheels installed. Consult your Superior pallet jack specification sheet or parts manual for load ratings. Do not exceed the jacks maximum lifting capacity regardless of wheel specifications.
Q: How do I diagnose a failed or failing SU S9116?
A: Watch for these signs: visible flat spots, chunks of rubber missing, uneven wear across the wheel face, difficulty rolling smoothly under load, audible grinding or squeaking, or visible polymer coating separation. If the wheel is worn beyond 1/8 inch or shows cracks, it cannot be repaired and must be replaced.
Q: How does SU S9116 wear compare to higher-durometer wheels?
A: At 95A hardness, SU S9116 provides moderate wear resistance. Higher-durometer wheels (100A and above) resist abrasion longer but may generate more heat and ride harder on rough floors. Lower-durometer wheels (90A and below) absorb shock better but wear faster. SU S9116 at 95A represents a balanced trade-off for standard warehouse duty.
