Frequently Asked Questions
Q: What is included in the SU 233-A load wheel assembly?
A: The SU 233-A is a complete load wheel assembly that includes the tread wheel, hub, and sealed ball bearings. This is a plug-and-play replacement unit, meaning all components are pre-assembled and ready to install on compatible electric lift trucks. If you need only the wheel tread without bearings and hub, order the SU 233 instead.
Q: How do I verify that the SU 233-A assembly is compatible with my lift truck?
A: Confirm compatibility by checking your equipment model and serial number against the manufacturer cross-reference table. Verify the wheel diameter, hub bore size, and axle mounting interface match your jack specifications. If you are uncertain, contact your equipment manufacturer or supplier with your lift truck model number and serial range.
Q: What is the difference between SU 233 and SU 233-A?
A: The SU 233 is the wheel tread only. The SU 233-A is the complete assembly, including the hub, sealed ball bearings, and tread. Use the SU 233-A if your bearings are worn or you want a complete replacement unit. Use the SU 233 if you only need the tread because your existing hub and bearings are still functional.
Q: How is the SU 233-A installed on my electric lift truck?
A: Lift the truck safely and secure it on level ground. Remove the axle pin or fastener holding the old wheel assembly. Slide the old assembly off the axle shaft. Clean any debris or corrosion from the axle. Slide the SU 233-A assembly onto the axle, ensuring the hub bore seats completely. Reinstall the axle pin and locking mechanism. Manually spin the wheel to confirm free rotation before operating the lift truck.
Q: What bearing type does the SU 233-A use and what is its service life?
A: The SU 233-A uses sealed ball bearings; specific bearing material and grade depend on the assembly specification. Service life is typically 300,000 to 400,000 rolling cycles under normal load and maintenance conditions. Actual lifespan depends on operating environment, consistent load, and bearing inspection and cleaning schedules.
Q: What should I do if the SU 233-A wheel assembly makes noise or does not spin freely?
A: Do not operate the lift truck if the assembly grinding, squeaking, or does not rotate smoothly. Remove the lift truck from service immediately. Remove the assembly from the axle and inspect the bearing for contamination, rust, or damage. If the bearing is seized, worn, or discolored, the entire SU 233-A assembly must be replaced. Do not attempt to disassemble sealed bearings.
