Frequently Asked Questions
Q: What bearing size is installed in the SU S629-XL-A assembly?
A: The SU S629-XL-A assembly uses a 25mm ID (0.984 inch) sealed bearing pre-installed on a precision-finished steel hub. The bearing is not user-serviceable. If the bearing fails, the entire assembly must be replaced. Verify your jack axle diameter is 25mm before ordering to prevent fit issues.
Q: Is the SU S629-XL-A a direct replacement for the SU S629-EZ-A?
A: Yes, if both jacks have identical bore diameter (2.0467 inches) and axle length. The assemblies are mechanically interchangeable. Do not mix 87A and 97A wheels on the same jack. If upgrading from 87A, replace all four wheels and verify load rating compatibility before operation.
Q: What cross-reference part numbers are equivalent to the SU S629-XL-A?
A: Equivalent part numbers include Superior SU629-XL, SU629XL, and 629XL. Alternative designations are SUS629-XL and SU 629-XL-A. All reference the same assembly with 97A Cushothane XL compound, XL3 bonding, and 25mm sealed bearing. Always verify with the OEM part number on your jack documentation.
Q: How long does the bearing last in the SU S629-XL-A assembly?
A: The sealed bearing typically lasts 3-4 years in normal operation with routine wheel assembly inspection. Life depends on floor debris, water exposure, and load cycling. If you hear clicking, grinding, or roughness when rotating the wheel by hand, the bearing is failing and the assembly must be replaced immediately.
Q: Can I disassemble the SU S629-XL-A to replace only the bearing?
A: No. The bearing is permanently bonded to the hub using XL3 technology. Attempting disassembly damages the hub and voids warranty. The entire assembly must be replaced as a unit. Field repair or bearing replacement is not possible and is not recommended for safety reasons.
