Frequently Asked Questions
Q: What is the difference between the S880-XL and S883-XL wheels?
A: The S883-XL is a caster wheel (7.874 inch diameter x 2.165 inch width) with a rubber tread and cast aluminum core. The S880-XL is a load wheel (3.25 inch diameter x 6.5 inch width) made of polyurethane. Caster wheels are swivel-mounted and steer the truck; load wheels support forward/backward movement. These are not interchangeable. Use the caster wheel only where a swivel caster is required by your truck design.
Q: Is the S883-XL compatible with electric lift trucks?
A: Yes. The S883-XL is designed for electric lift trucks as a front caster wheel. It features a precision ball bearing and cast aluminum hub for smooth steering. Verify that your truck has a caster mount point with the correct bore and swivel pin diameter before ordering. Hand pallet jacks and stainless steel carts may use different caster specifications.
Q: What causes uneven wear on S883-XL caster wheels?
A: Misalignment of the caster swivel pin, loose bearing bolts, or bent caster forks cause uneven or feathered tread wear. If the tire wears down on one edge first, check the swivel pin alignment and ensure the bearing is not binding. Dragging the truck sideways at speed also causes scuffing. Inspect caster alignment quarterly. If wear is diagonal across the tread, the caster fork may be bent and requires replacement.
Q: Can the S883-XL rubber tread be replaced without changing the wheel?
A: No. The S883-XL is a molded rubber-on-aluminum assembly and the tread cannot be replaced separately. When tread wears down or chunks are missing, the entire wheel must be replaced. Attempting to machine or resurface a rubber tire will damage the aluminum core and bearing seat. Order a complete replacement wheel, not just the tire.
Q: What is the load rating for the S883-XL caster wheel?
A: The S883-XL caster is rated for typical electric lift truck capacity, generally 2,000 to 4,000 lbs per wheel depending on the truck model. The actual load on each caster is less than half the truck rating because load wheels carry most of the weight. Consult your truck manual for the exact caster load limit. Do not exceed truck capacity; overloading damages the bearing and caster fork.
Q: Is the S883-XL equivalent to SUS883-XL?
A: Yes. SU S883-XL and the alternate designation SUS883-XL are the same caster wheel. Both refer to the 7.874 inch diameter rubber-tread caster with precision ball bearing and cast aluminum hub. Use whichever part number your system recognizes. No cross-references or superseding part numbers are known; if you need a caster upgrade, consult your truck OEM for compatible alternatives.
