Frequently Asked Questions
Q: What material should I choose for the SU S623, polyurethane or nylon?
A: Choose nylon for light-to-moderate duty (3-5 hour shifts) and general material handling. Choose polyurethane for high-duty cycles (8+ hour shifts), wet environments, or if the wheel will contact oils or chemicals. Polyurethane costs 20-30 percent more but lasts 40-50 percent longer in demanding conditions.
Q: Is the SU S623 compatible with other load wheel models like SU S621-XL?
A: Compatibility depends on your lift truck model and mounting bore size. The SU S623 may have different diameter, width, or bearing bore than the S621-XL. Cross-reference your truck documentation or OEM manual for the correct wheel part number. Do not assume interchangeability based on model number similarity.
Q: What mounting system does the SU S623 use and does it require modifications?
A: The mounting system and bore specifications are not fully detailed in standard product data. Verify bearing bore ID, axle bolt size, and wheel hub width against your truck assembly before ordering. Installation is typically plug-and-play if dimensions match, but modifications to the axle or frame are not recommended without manufacturer guidance.
Q: How often should I inspect and replace SU S623 wheels?
A: Inspect wheels monthly for tread wear, chunking, flat spots, or bearing play. Nylon wheels typically last 18-36 months in normal use. Polyurethane wheels last 24-48 months. Replace immediately if the wheel does not spin freely, binds, or if tread is worn more than 25 percent of the original thickness.
Q: Can I mix nylon and polyurethane wheels on the same lift truck?
A: It is not recommended. Mixing materials with different hardness and wear rates on a single truck will cause uneven tread wear, tilting, and reduced load stability. If you must upgrade wheels, replace all wheels of the same type (all load wheels or all guide wheels) with the same material to maintain balance and performance.
