Frequently Asked Questions
Q: What is included in the SU S9149-EZ-A Load Wheel Assembly?
A: The SU S9149-EZ-A is a complete, ready-to-install assembly. It includes the polyurethane load wheel with High Traction EZ compound, the nylon core, precision ball bearings, and the mounting hub. No additional bearing or hub procurement is required. You receive a bolt-on complete unit.
Q: How does the SU S9149-EZ-A compare to the standard SU S9149-EZ wheel?
A: The SU S9149-EZ is the wheel alone; you supply or reuse the bearing and hub assembly from your old wheel. The SU S9149-EZ-A includes pre-assembled bearings and hub, saving labor time and eliminating the risk of bearing press-fit errors. If you do not have a bearing press or do not want to manage bearing installation, the -A designation assembly option is faster and reduces failure risk from improper bearing seating.
Q: Is the SU S9149-EZ-A a plug-and-play replacement?
A: Yes, in most cases. The assembly bolts directly onto the truck axle or bracket. However, verify mount bolt size and spacing with your equipment manual before installation. Some electric truck models use different bolt patterns. Confirm the axle bore diameter matches the hub bore. If in doubt, test fit before final fastening.
Q: What floor conditions is the SU S9149-EZ-A rated for?
A: The EZ High Traction compound is engineered for wet floors, cold storage at sub-zero temperatures, and mixed indoor-outdoor operations. It provides reliable grip on damp concrete, ice, and salt-treated surfaces. In dry warehouses, the wheel performs well but may not offer the maximum wear life compared to softer compounds designed specifically for dry floors.
Q: What is the expected service life of the SU S9149-EZ-A assembly?
A: In wet and cold storage environments with continuous rolling service, expect 12 to 18 months of useful life before tread wear or damage requires replacement. In dry facilities, service life may extend to 18 to 24 months. Replace the assembly when tread depth falls below 50 percent of original, visible cracks appear, or bearings show noise and binding.
Q: Can I replace just the wheel tread if the bearing and hub are still good?
A: No. The SU S9149-EZ-A is a molded assembly; the polyurethane tread is bonded to the core and cannot be separated. If only the tread is worn but the bearing and hub are serviceable, you must purchase a new assembly or opt for a wheel-only SKU (if available) and reuse your existing bearing and hub. This is a complete replacement unit.
