Poly wheel 97A, 4 x 1-7/8
Frequently Asked Questions
Q: What is the load capacity and nominal size of the SU S541-XL-A wheel?
A: The SU S541-XL-A is a poly wheel with 97A durometer rating, nominal dimensions 4 x 1-7/8 inches. The 97A hardness makes it suitable for smooth indoor floors where moderate load distribution is needed. This wheel is designed for electric lift trucks requiring a smaller profile load wheel.
Q: Is the SU S541-XL-A compatible with SU S542 series applications?
A: No. The SU S541-XL-A has different dimensional specs (4 x 1-7/8) compared to the larger SU S542 series (4 x 2-7/8). Do not interchange them. Verify your truck model and required wheel bore diameter before ordering. Cross-reference your equipment manual to confirm the correct SKU.
Q: What installation tools are needed to replace the SU S541-XL-A?
A: You will need a bearing puller, arbor press, and the correct bore size socket or sleeve. The wheel is press-fit onto the axle. Do not use a hammer or mallet as this damages the bearing and hub. Press slowly and evenly. Always inspect the axle for wear or scoring before installing a new wheel.
Q: How often should the SU S541-XL-A wheel be inspected for wear?
A: Inspect the wheel weekly during normal operation. Look for flat spots, tread separation, or bearing play. Replace immediately if the tread is worn more than 25 percent or if side-to-side movement exceeds 0.125 inches at the rim. High-friction applications may require replacement every 6 to 12 months depending on load and hours.
Q: Can the SU S541-XL-A wheel be used on damp or wet floors?
A: Yes, but with caution. The 97A poly compound has moderate slip resistance on wet surfaces. In wet environments, reduce speed and apply more frequent cleaning to the wheel surface to remove any algae or debris buildup. For constant wet-floor operation, consider upgrading to a higher-durometer or grooved wheel variant.
Q: What bearing type comes on the SU S541-XL-A and is it replaceable?
A: The wheel uses a press-fit ball bearing. The bearing is not field-serviceable and cannot be removed and regreased. Once the bearing fails or seizes, the entire wheel assembly must be replaced. Do not attempt to drive out the bearing as this will damage the hub bore.
