Frequently Asked Questions
Q: What does the XL-A designation mean compared to standard SU 626-XL?
A: The XL-A designation indicates the wheel uses proprietary advanced bonding technology that adheres polyurethane tread to the steel core more strongly than standard SU 626-XL wheels. This superior bonding provides enhanced cut and tear resistance, critical for high-frequency duty cycles and harsh environments. The XL-A is a direct upgrade to SU 626-XL with the same 3.25 x 2.875 inch dimensions, bore, and load capacity.
Q: Can I replace a failed SU 626-XL wheel with SU 626-XL-A on a mixed-fleet pallet jack?
A: Yes. SU 626-XL-A is a drop-in replacement for SU 626-XL. Both wheels have identical 3.25 inch OD, 2.875 inch width, 1.938 inch ID bore, and 95 Shore A Cushothane XL material. You can mix SU 626-XL and SU 626-XL-A wheels on the same equipment without compatibility issues. However, installing only SU 626-XL-A wheels on all four positions provides uniform performance and wear characteristics across the fleet.
Q: When should I choose SU 626-XL-A over SU 626-XL for a specific application?
A: Use SU 626-XL-A when your application involves frequent sharp turning, rough floors with gravel or metal shavings, chemical exposure, or continuous duty cycles exceeding 16 hours daily. The advanced bonding in SU 626-XL-A reduces polyurethane separation and tread chunks in these harsh environments. For standard light-to-medium duty (8 to 10 hours daily, smooth concrete), standard SU 626-XL is sufficient and more cost-effective.
Q: How do I diagnose if the polyurethane is separating from the core on SU 626-XL-A?
A: Separation symptoms include visible cracking, chunks missing from the tread, or the wheel feeling slightly loose or wobbling despite a tight axle nut. Inspect by visually examining the tread for gaps between the polyurethane and steel hub, especially at edges. Feel the wheel by hand for soft spots or areas where the tread shifts. If separation is detected, stop using the wheel immediately. Continued operation risks core exposure and wheel failure.
Q: What maintenance extends the life of SU 626-XL-A wheels in a warehouse environment?
A: Clean wheels monthly using dry brushing to remove dust, oil, and chemical residue that can degrade polyurethane. Avoid high-pressure washers that force water into bearing seals. Inspect tread quarterly for cuts, chunks, or separation. Rotate wheels every 6 months if your equipment operates in one direction for extended periods, as this promotes even wear. Replace wheels immediately if the core is exposed or more than 25 percent of tread height is worn.
Q: Is SU 626-XL-A suitable for wet or oily floor conditions?
A: Yes, SU 626-XL-A handles wet and oily floors reasonably well. The 95 Shore A hardness and smooth tread profile provide adequate traction on these surfaces. However, in continuously wet environments or where chemical oils accumulate, traction is reduced compared to grooved wheels. The Cushothane XL material resists oil absorption but can soften slightly with prolonged exposure to petroleum products. For critical wet applications, consult the OEM about specialized tread profiles.
