Frequently Asked Questions
Q: What is the difference between SU S459 and SU S459-A?
A: SU S459 is a wheel only. SU S459-A is a complete wheel assembly that includes bearings and the wheel. If you are replacing a bare wheel or installing on an existing axle with good bearings, order SU S459. If you need a drop-in replacement assembly with new bearings, order SU S459-A.
Q: What applications is the SU S459 wheel rated for?
A: SU S459 is engineered for electric lift truck load wheels. The 6 inch diameter by 3 inch width with 3/8 inch radius tread provides smooth rolling on both smooth and slightly textured warehouse floors. Do not use on rough, outdoor, or inclined surfaces. Maximum load capacity depends on your jack frame and bearing specification.
Q: What is the bore depth and how do I measure it?
A: The SU S459 has a bore depth of 0.78 inches and a bore outside diameter of 2.4404 inches. Measure from the inside edge of the wheel rim inward to determine bore depth. If your axle stub is longer than 0.78 inches, the wheel will not seat properly. Use spacer washers if needed to center the wheel on the axle.
Q: Can I mix SU S459 with other wheel sizes on the same jack?
A: No. All wheels on an electric lift truck must be the same diameter and width to ensure level load distribution and prevent binding. Mixing 6 inch wheels with 5 inch wheels will cause the jack to tilt and damage the frame. Always replace wheels in complete sets of four or eight depending on your jack design.
Q: What tread hardness does SU S459 have?
A: SU S459 is manufactured from Cushothane XL material. This polyurethane-based tread provides consistent rolling resistance and floor grip without being specified as a hardness rating like Shore 97A or 98A. Cushothane XL is standard for warehouse electric lift truck applications on indoor smooth floors.
Q: How often should SU S459 wheels be inspected?
A: Inspect SU S459 wheels monthly in regular warehouse use, or every 50 operating hours on high-use forklifts. Check for flat spots, cracks, uneven wear, and tread depth. If flat spots develop, the wheel must be replaced. Worn wheels reduce traction and increase strain on bearings and the jack frame.
