SU S9141-XL-A-R

Frequently Asked Questions

Q: Is SU S9141-XL-A-R equivalent to any other load wheel part numbers?
A: SU S9141-XL-A-R is the OEM part number equivalent to manufacturer part number SU 9141-XL. Both refer to the same polyurethane load wheel assembly with 97A durometer Cushothane XL material. Always verify your equipment documentation to confirm SU 9141-XL format fitment before ordering, as wheel compatibility is determined by bore diameter (1.938 inch) and width (6.5 inch) as well as the 3.25 inch outside diameter.

Q: What electric lift truck models use the SU S9141-XL-A-R load wheel?
A: The SU S9141-XL-A-R is designed for electric pallet jacks and electric lift trucks that call for SU 9141-XL format load wheels. This 3.25 inch diameter x 6.5 inch width wheel is commonly found on compact electric stackers and walkie-rider platform trucks. Verify compatibility by checking your equipment specification plate or parts manual for load wheel dimensions and bore size. The 1.938 inch bore diameter must match your existing wheel hub.

Q: How do I diagnose if the SU S9141-XL-A-R wheel needs replacement?
A: Replace the wheel when you observe uneven wear, flat spots, or chunks missing from the tread surface. Listen for grinding or squealing during operation, which indicates internal bearing damage or tread separation. Visually inspect for cracks radiating from the bore or severe glazing (shiny, slippery surface). If the wheel is 5+ years old and used in wet or cold storage, it may lose grip even if tread appears intact. Test load wheel grip by manually rolling the equipment on a clean, dry floor. If it slides easily or pulls to one side, one or more wheels are failing.

Q: What tools and safety precautions do I need to replace the SU S9141-XL-A-R wheel?
A: You will need a socket set and wrench to remove the wheel axle bolt, and a press or bearing puller if the wheel is press-fit onto the axle shaft. If the wheel is bolted on, a hand tool replacement takes 5-10 minutes per wheel. Always block or lift the equipment safely on jack stands so the load wheel is not under load. Do not work under a suspended load truck. If the wheel is pressed on and requires a specialized press, contact our technical team for detailed removal guidance. New wheels may ship with factory grease, so inspect the bearing area before installation.

Q: What is the load capacity and operating limit for the SU S9141-XL-A-R?
A: The SU S9141-XL-A-R is rated for electric pallet jack and lift truck duty per the OEM equipment design. Actual load capacity depends on your specific truck model, the number of load wheels, and whether the truck is rated for floor or ramp use. The 97A durometer polyurethane provides firm grip and durability in general warehouse conditions. Do not use polyurethane wheels in outdoor or extremely hot environments (above 140 degrees Fahrenheit), as the material will degrade and lose grip. Consult your truck OEM documentation for the truck total load rating and wheel-specific pressure limits if applicable.

Q: How should the SU S9141-XL-A-R be maintained to extend its life?
A: Inspect the wheel and axle bearing every 250 operating hours for wear, contamination, or excessive play. Clean the wheel tread with a damp cloth monthly to remove dirt buildup that can reduce grip and increase slipping. Check the axle bolt for tightness, as vibration can loosen the wheel over time. If the wheel develops a flat spot or significant wear pattern, it indicates an alignment or load distribution problem. Rotate wheels from front to rear on the same truck if uneven wear is visible. Proper maintenance extends wheel life from 3-5 years to 5-7 years depending on duty cycle. Do not apply water or solvents directly to the bearing area during cleaning.
