Frequently Asked Questions
Q: What are the specifications of the 65A polyurethane load wheel?
A: The 65A is a polyurethane load wheel measuring 180 mm diameter with 50 mm tread width, 20 mm bore, and 1.76 inch hub length. The wheel has a 65 Shore D durometer hardness, weighs capacity of 1900 lbs per wheel, and features a chemically bonded polyurethane tread bonded to a cast iron core. It is equipped with a sealed 6204 precision ball bearing rated for wide temperature ranges.
Q: What manual pallet jack models is the 65A load wheel compatible with?
A: The 65A fits manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar OEM manufacturers with 180 mm wheel openings and 20 mm bore hubs. Verify your equipment hub diameter, bearing type, and frame spacing match the 65A specifications before ordering.
Q: What are the performance characteristics of polyurethane tread on the 65A wheel?
A: The 65 Shore D polyurethane tread provides good abrasion resistance, moderate load distribution, and stable handling on level concrete floors. The chemically bonded construction prevents tread delamination. Polyurethane offers better floor grip and lower rolling resistance compared to nylon, making it suitable for standard indoor warehouse use.
Q: What is the load capacity per wheel for the 65A, and what happens if the capacity is exceeded?
A: Each 65A wheel is rated for 1900 lbs. For a manual pallet jack with two load wheels, total capacity is approximately 3800 lbs depending on weight distribution and equipment design. Exceeding capacity causes permanent polyurethane compression, accelerated bearing wear, frame deflection, and unsafe handling characteristics.
Q: How long does the 65A wheel typically last in service?
A: With normal warehouse duty and proper maintenance, the 65A should provide 3 to 5 years of service before polyurethane tread degradation or bearing wear necessitates replacement. High-frequency use, continuous outdoor exposure, or impact loads reduce lifespan. Sealed bearing design minimizes water ingress and extends operational life.
Q: What maintenance does the 65A sealed bearing require?
A: The sealed 6204 ball bearing requires no field lubrication. Inspect the seal annually for damage, water infiltration, or rust around the hub. If the wheel squeaks, spins unevenly, or feels rough when rotated by hand, bearing failure is likely and wheel replacement is required.
