Frequently Asked Questions
Q: What is the difference between the SU 448-XL-A assembly and a standard load wheel?
A: The SU 448-XL-A is a complete load wheel assembly, not just a wheel. It includes a polyurethane tread bonded to a steel hub using XL3 bonding agent, a 17 mm bore, and a double-sealed 6203-2RS ball bearing. The assembly is ready to install on the axle. A standard wheel requires you to transfer the bearing from the old axle.
Q: What is the rated load capacity of the SU 448-XL-A assembly?
A: The SU 448-XL-A is rated for 1500 lbs static load capacity. This rating applies when the assembly is properly installed on a compatible lift truck and used under normal industrial duty. Do not exceed the truck nameplate load capacity, which may be lower than the wheel rating.
Q: How does XL3 bonding technology improve the SU 448-XL-A performance?
A: The XL3 bonding agent creates a non-separating adhesive interface between the polyurethane tread and steel hub. Testing shows the SU 448-XL-A delivers up to 2x service life compared to traditional steel hub load wheels. This reduces replacement frequency and reduces downtime for industrial operations running heavy duty cycles.
Q: Is the 6203-2RS bearing included with the SU 448-XL-A and can I replace it separately?
A: Yes, the double-sealed 6203-2RS ball bearing is included in the assembly. The bearing is sealed on both sides to keep out dirt and moisture. If the bearing fails, you can replace it separately without replacing the entire wheel. The bearing can rotate freely by hand when the assembly is off the truck.
Q: What maintenance is required for the SU 448-XL-A assembly?
A: The double-sealed bearing requires no lubrication because the seals trap factory grease inside. Inspect the wheel monthly for cracks, uneven wear, or wobbling. Replace the assembly if the tread separates from the hub, the bearing seizes, or noise comes from the wheel during operation. Proper floor maintenance prevents debris buildup that can damage the tread.
