Frequently Asked Questions
Q: What is the weight capacity and load rating for SU 653-XL-A wheels?
A: SU 653-XL-A is rated for 2,200 pound dynamic load per wheel, or 8,800 pounds total distributed across four wheels on a standard pallet jack. The integrated shoulder bearings allow sustained loads without overheating up to 4,000 pound rack capacity. Do not exceed this rating - overload causes bearing race damage within 50-100 operating hours, leading to wheel seizure.
Q: How do I install SU 653-XL-A and do I need to replace bearings?
A: The SU 653-XL-A assembly arrives with sealed precision bearings pre-installed - do not disassemble or repack them. Installation requires only an Allen wrench to remove the old wheel and axle bolt, then slide the new wheel onto the axle and hand-tighten the bolt to 45 foot-pounds. Verify the wheel spins freely without wobble. Installation takes 5 minutes per wheel. If the axle is bent, replace it before installing new wheels.
Q: What maintenance is required for the integrated shoulder bearings on SU 653-XL-A?
A: Sealed bearings require no lubrication or maintenance. Do not attempt to inject grease - the seals are not designed for relubrication. If you hear grinding or clicking from a bearing after 12 months of operation, the bearing race is damaged and the entire wheel assembly must be replaced. Bearing failure cannot be field repaired. Operate in dry conditions below 120 degrees Fahrenheit to maximize bearing lifespan to 24-30 months.
