Frequently Asked Questions
Q: What components are included in the SU S9433-XL-A caster wheel assembly?
A: The SU S9433-XL-A is a complete caster assembly consisting of a mounting bracket (steel, powder coated), high-impact polymer bushings, shaft, and a high-strength polyurethane roller. All components are engineered for direct OE replacement and assembled to specification for plug-and-play installation on compatible electric lift truck systems.
Q: Is SU S9433-XL-A the same as the individual SU S9433-XL wheel, or do I need both?
A: No, you purchase one or the other depending on your equipment configuration. SU S9433-XL is the wheel core only. SU S9433-XL-A is the complete assembly with mounting bracket and bushings. If your truck requires pre-assembled caster units, purchase SU S9433-XL-A. If you only need the wheel itself, purchase SU S9433-XL.
Q: What bushing and bracket materials are used in the SU S9433-XL-A assembly?
A: The mounting bracket is heavy-duty steel with a powder-coat finish for corrosion resistance. Bushings are industrial-grade polymer engineered to reduce friction and noise while maintaining load capacity. The polyurethane roller provides traction and durability under typical electric lift truck service conditions.
Q: How do I install the SU S9433-XL-A assembly on my lift truck?
A: Remove fasteners securing the old caster assembly to the truck frame or carriage. Align the SU S9433-XL-A mounting bracket with the existing bolt holes and install with the specified fasteners. Verify all bolts are tight and the assembly rotates freely before returning the truck to service. Do not operate until installation is complete and verified.
Q: What maintenance is required for the SU S9433-XL-A assembly to extend its lifespan?
A: Periodically inspect the bracket for cracks or corrosion and check that all bolts remain tight. Verify the roller tread for wear or flat spotting. If bushings show signs of wear (excessive play or noise), the assembly may need replacement. Clean the assembly regularly and lubricate the shaft per your truck manufacturer recommendations.
Q: What OEM part numbers cross-reference to the SU S9433-XL-A?
A: The SU S9433-XL-A is referenced as OEM part number SU9433-XL-A. It is equivalent to the SU S9433-XL wheel core for applications requiring a full assembly. Contact our parts team with your lift truck make and model to confirm cross-references with other OEM equipment manufacturers.
