Frequently Asked Questions
Q: What equipment is the SU 9163-XL-A load wheel designed for?
A: The SU 9163-XL-A is engineered for select electric lift truck and pallet jack models requiring a 6.00 inch diameter x 4.125 inch width load wheel assembly. Verify your equipment manual lists these exact dimensions and confirms compatibility with double-bearing configuration wheels.
Q: What is the significance of the 93A Shore hardness specification?
A: 93A Shore A durometer indicates medium-high polyurethane tread hardness. This specification provides a balanced combination of wear resistance and floor grip compared to lower durometer wheels. Cushothane XL material at 93A is suitable for heavy industrial use with good performance on concrete and sealed floors.
Q: What are the bore specifications for the SU 9163-XL-A?
A: The SU 9163-XL-A features a 1.85 inch bore with 2.947 inch inside diameter and 3.00 inch bore outside diameter. Bore depth is 0.827 inch. These specifications must match your equipment axle shaft size exactly for proper installation. Incorrect bore sizing will result in misalignment and steering problems.
Q: What is the benefit of the double-bearing configuration?
A: Double-bearing wheels provide superior load distribution and spindle support compared to single-bearing designs. This reduces radial play, improves steering precision, extends bearing life, and minimizes wobbling during operation. Double bearings are standard for heavy-duty electric lift truck applications.
Q: How do I install the SU 9163-XL-A wheel assembly?
A: Secure the lift truck and remove the axle bolt. Slide the old wheel off the shaft. Position the SU 9163-XL-A assembly and install the retaining bolt hand-tight first. Verify alignment and wheel position, then tighten the bolt firmly using proper wrench size. Check rotation is smooth without binding.
Q: What are the metric dimensions for the SU 9163-XL-A?
A: The wheel measures 152.40 mm diameter x 104.77 mm width. These metric dimensions correspond to the 6.00 inch x 4.125 inch specification. Use metric measurements when cross-referencing international part numbers or manufacturer equivalents.
