Frequently Asked Questions
Q: What does XL Yellow mean on the SU STR53001 caster assembly?
A: XL refers to the extra-large wheel diameter or load capacity of the caster assembly. Yellow typically indicates the color of the wheel or the polyurethane compound used. The exact wheel size and material are defined in the product specifications. Check the diameter, width, and material specifications before ordering to ensure fit on your truck.
Q: Is the SU STR53001 suitable for heavy-duty or high-load applications?
A: The XL designation suggests an increased load capacity compared to standard casters. Verify the maximum load rating of the SU STR53001 against your truck model and intended load weight. Exceeding the load rating will cause premature wheel wear, bearing failure, and unsafe truck handling. Check your truck manual for the recommended caster load class.
Q: Can I swap a standard caster assembly for the SU STR53001 XL assembly?
A: Only if mounting dimensions and truck frame clearance allow. The XL wheel diameter is larger than standard casters, which may require frame or suspension adjustment. Verify that the larger wheel does not interfere with the truck body, mast, or surrounding components. Consult your truck documentation or contact our technical team with your truck model and serial number.
Q: What maintenance is required for the SU STR53001 caster assembly?
A: Inspect the yellow wheel for cracks, flat spots, or uneven wear every 200 operating hours. Clean the wheel and bearing area of debris, salt, and moisture. Check that all mounting fasteners remain tight. Lubricate the bearing pivot per your truck schedule, typically every 250 hours. If the wheel shows significant wear or damage, replace the entire assembly to maintain steering precision and load stability.
