Frequently Asked Questions
Q: What is the key difference between the SU 628-XL and SU 627-XL?
A: Both wheels have 3.25 inch diameter, but the SU 628-XL is 5.937 inches wide while the SU 627-XL is only 2.000 inches wide. The SU 628-XL is designed for lift trucks that require wider load wheels for improved lateral stability and load distribution. Check your equipment manual to confirm which width your jack requires.
Q: Can I use the SU 628-XL as a replacement for SU 629?
A: Both the SU 628-XL and SU 629 have the same 3.25 x 5.937 inch dimensions, but they may differ in durometer hardness and material composition. The SU 628-XL uses Cushothane XL material while SU 629 uses polyurethane with 95A hardness. Check your jack manual for the specified hardness and material grade required. Installing an incorrect hardness rating can result in premature wear or insufficient load support.
Q: What are the bore specifications for the SU 628-XL?
A: The SU 628-XL has a 1.938 inch inside diameter, 2.0467 inch bore outside diameter, 0.591 inch bore depth, and 5.937 inch hub width. These specifications must match your lift truck axle to ensure proper fitment and prevent wobbling. Measure your axle before ordering to avoid installation issues.
Q: What is the metric equivalent of the SU 628-XL dimensions?
A: The SU 628-XL measures 82.55 mm diameter x 150.80 mm width in metric units. This metric designation helps identify compatible wheels when working with internationally manufactured lift truck equipment.
Q: How do I diagnose uneven wear on the SU 628-XL?
A: Uneven wear on the 5.937 inch width indicates axle misalignment or improper bearing preload. Inspect for worn bearings and axle play before replacement. If the outer edges wear faster than the center, the axle is bent or not properly supported. Address the underlying mechanical issue or the replacement wheel will fail prematurely.
