Frequently Asked Questions
Q: Is the SU S652-XL-A a complete assembly or do I need additional hardware?
A: SU S652-XL-A is a complete load wheel assembly. It includes the wheel, hub, sealed bearings, and all internal components. Installation typically requires only removal of the old assembly and fastening of the new axle to your jack frame. Do not disassemble the bearing cartridge; the assembly is sealed and pre-lubricated.
Q: What is the installation procedure for the SU S652-XL-A?
A: Raise and secure your electric jack on a stable surface. Remove fasteners (typically bolts or clips) holding the old load wheel assembly to the frame. Slide the old assembly off the axle. Position the new SU S652-XL-A assembly and align axle holes with frame mounting points. Install fasteners and torque to manufacturer specification (typically 35-50 foot-pounds for frame bolts). Rotate the wheel by hand to confirm smooth operation before lowering the jack.
Q: How long does the SU S652-XL-A bearing last before replacement?
A: Sealed precision bearings in the SU S652-XL-A typically last 12-18 months under normal electric jack duty (40-60 hours per week). Lifespan shortens significantly if the jack operates overloaded, in wet environments without drainage, or with poor floor maintenance. Once bearings begin to bind or the wheel produces grinding noise, the entire assembly should be replaced. Bearing repair is not recommended.
Q: What tread material does the SU S652-XL-A use?
A: The tread composition is proprietary polyurethane formulation designed for balanced wear resistance and grip. The specific Shore A hardness rating determines grip and wear rate. Confirm the hardness rating with your parts spec sheet. Polyurethane treads are non-marking and safe for finished floors.
Q: Can I replace just the wheel tread on the SU S652-XL-A assembly?
A: No. The SU S652-XL-A is a sealed, press-fitted assembly. The wheel tread is bonded to the steel hub core and cannot be separated without destroying the hub. When tread wear exceeds 50 percent of original depth or damage occurs, replace the entire assembly.
Q: Is the SU S652-XL-A suitable for both indoor and outdoor use?
A: Yes. The polyurethane tread is formulated for both indoor and outdoor use. However, when operating outdoors, rinse the wheels and frame weekly to remove salt, sand, and debris. Bearing seals protect against light splash but not immersion. Do not operate submerged or in standing water.
