Frequently Asked Questions
Q: Is the SU S2377-A a direct OEM replacement for older lift truck models?
A: Yes, the SU S2377-A is a direct OEM replacement part for equipment specifying SU 2377 or SU S2377-A. It is compatible with standard axle fitment. Verify your original part number against the manufacturer documentation before ordering to ensure compatibility with your specific model year and serial number.
Q: What does the SU S2377-A assembly include?
A: The SU S2377-A is a complete load wheel assembly that includes the wheel hub, 20 mm sealed precision bearing, and red polyurethane tread pre-assembled. It is shipped ready to install and requires no disassembly or additional bearing work.
Q: Are there any cross-reference part numbers for the SU S2377-A?
A: No cross-reference part numbers are available for the SU S2377-A. Use only this exact part number when ordering. If you are replacing equipment from a different manufacturer, contact the OEM or supplier with your equipment serial number to identify the correct replacement part.
Q: What is the axle fitment for the SU S2377-A?
A: The SU S2377-A uses standard axle fitment with a 20 mm hub bore. Measure your existing axle diameter to confirm compatibility before installation. The assembly slides directly onto the axle and is secured with a retaining clip or cotter pin.
Q: How do I know if the SU S2377-A bearing has failed?
A: Signs of bearing failure include grinding noise during operation, loose or wobbly wheel movement, wheel dragging or not rolling smoothly, and side-to-side play when manually rocking the wheel. If any of these symptoms appear, replace the assembly immediately. Continuing operation with a failed bearing risks equipment damage and injury.
Q: Is the SU S2377-A sealed bearing assembly field-serviceable?
A: No. The sealed bearing assembly is not designed for field service. If the bearing fails or the tread is excessively worn, replace the entire SU S2377-A assembly. Attempting to disassemble or re-lubricate the sealed bearing compromises the seal and voids the warranty.
