Frequently Asked Questions
Q: What are the cross-reference part numbers for the SU 9111?
A: The SU 9111 has documented cross-references to SU S9111-XL and SU 9111-XL-A. When ordering replacement wheels, always use the exact part number from your equipment documentation. If your jack calls for SU S9111-XL or SU 9111-XL-A, the SU 9111 may provide equivalent fitment, but verify with our technical team to confirm compatibility.
Q: What are the dimensions of the SU 9111 load wheel?
A: The SU 9111 has an outside diameter of 6.000 inches and a width of 2.750 inches. Confirm these dimensions match your current wheel assembly before ordering. A size mismatch will prevent proper installation and may damage your jack steering or load capacity.
Q: Is the SU 9111 interchangeable with other 6 inch load wheels?
A: The SU 9111 is not universally interchangeable with all 6 inch load wheels. Bore diameter, hub width, and axle mounting style vary between wheel designs. Cross-reference equivalence exists for SU S9111-XL and SU 9111-XL-A only. Verify your current part number matches before assuming fitment. Contact us with your equipment details if unsure.
Q: What diagnostics should you perform if a jack with SU 9111 wheels pulls to one side?
A: When a jack with SU 9111 wheels pulls to one side, first inspect both left and right wheels for flat spots, cracks, or uneven wear. Manually spin each wheel to check for smooth rotation and binding. If one wheel is deformed or stiff while the other rolls freely, replace the damaged wheel. If both wheels appear normal, the issue may be hydraulic or steering linkage related.
Q: How do I know if the SU 9111 bore is worn and causing axle play?
A: Grasp the SU 9111 wheel firmly and try to move it side to side on the axle. Slight play is normal, but excessive movement (more than 1/4 inch side to side) indicates bore wear or bearing failure. Also check if the wheel tilts up or down when pushed. Excessive play requires immediate replacement to prevent jack instability and potential tipping hazards.
Q: What is the typical replacement interval for the SU 9111?
A: The SU 9111 lifespan depends on operating hours, load utilization, and floor conditions. Typical service intervals are 18 to 36 months in regular warehouse use. Inspect wheels monthly for wear, flat spotting, and bearing play. Replace immediately if cracks appear, if the wheel locks up, or if axle play exceeds normal limits. Early replacement prevents safety hazards and unplanned downtime.
