Frequently Asked Questions
Q: What is the difference between SU S9141-XL-C3 and SU S9141-XL-A-R?
A: Both wheels share the same core dimensions: 3.25 inch outside diameter, 1.938 inch bore, and 6.5 inch width. The C3 designation typically indicates a specific core material or manufacturing configuration. The A-R designation indicates an assembly ready for installation. If you have existing SU 9141-XL-A-R wheels and need a replacement, verify the bore depth (1.43 inch for both) and bore outside diameter (2.0467 inch) match your axle design. Contact our technical team with your truck model and serial number to confirm which version is correct for your equipment.
Q: Which electric lift truck models are compatible with the SU S9141-XL-C3?
A: The SU S9141-XL-C3 fits electric pallet jacks and stackers that call for a 3.25 inch diameter load wheel with 1.938 inch bore and 6.5 inch width. Confirm compatibility by measuring your existing wheel or cross-referencing your equipment specification tag. The wheel hub width must be 6.5 inches to accommodate the full wheel width. If your truck has adjustable wheel spacing, you may fit a narrower wheel, but do not install a 6.5 inch wide wheel on a 6 inch or narrower hub, as it will cause binding and steering problems.
Q: Can I mix SU S9141-XL-C3 wheels with other load wheel types on the same truck?
A: No. All load wheels on a truck must be the same diameter, width, and material durometer to ensure even load distribution and predictable steering. Mixing wheel types causes uneven wear, pulling to one side, and erratic handling. If you are replacing wheels, replace all four load wheels at the same time whenever possible. If budget requires a phased replacement, replace wheels on the same axle in pairs (front or rear) to maintain balanced handling until all wheels are renewed.
Q: Is the SU S9141-XL-C3 pre-assembled or does it require bearing installation?
A: The SU S9141-XL-C3 is a complete assembly with bearings installed. You do not need to press or install bearings. Simply remove your old wheel from the axle and install the new wheel. If your old wheel is bolted on, unbolt it. If it is press-fit, you will need a press or bearing puller to remove it. Installation is the reverse: slide the new wheel onto the axle and secure with the bolt or press-fit per your truck design. Verify that the bearing spins freely by hand before lowering the truck to the floor.
Q: What material is the SU S9141-XL-C3 tread made from?
A: The SU S9141-XL-C3 uses Cushothane XL polyurethane tread material. Cushothane XL is a molded polyurethane compound designed for electric lift truck load wheels. It provides non-marking tread that does not leave black rubber marks on floors, and it offers good grip on dry warehouse floors and moderate cold storage environments. Cushothane XL wheels are not rated for outdoor use, extremely hot environments, or prolonged exposure to oils and solvents. If your equipment operates in wet floors or freezing cold storage, confirm with our technical team whether you need a specialized High Traction polyurethane wheel instead.
Q: How often should the SU S9141-XL-C3 be inspected and replaced?
A: Inspect the wheel every 250 operating hours for visible wear, cracks, or flat spots. Under normal duty (8 hours per day in a warehouse), expect a lifespan of 3-5 years. In heavy-duty applications (16+ hours daily with high cycle count), lifespan may be 2-3 years. Cold storage use may extend life due to reduced heat cycling, but inspect more frequently for microcracks. Replace the wheel immediately if you observe tread separation, severe flat spots, or any visible cracking that radiates from the bore. Do not repair or re-tread polyurethane load wheels; replacement is the only solution.
