Frequently Asked Questions
Q: What are the exact dimensions and material specifications for the SU S650 wheel?
A: The SU S650 is a 5 x 2 poly load wheel manufactured from Cushothane XL material. Overall dimensions are 5.000 inch diameter by 2.000 inch width (127mm x 50.8mm). The inside diameter is 1.938 inches, hub width is 2 inches, and bore outside diameter is 2.0467 inches with a bore depth of 0.591 inches. The tread profile is angled for directional control.
Q: Can I use the SU S650 as a direct replacement for the SU S650-XL wheel?
A: Both wheels share identical core dimensions and bore specifications but differ in durometer rating. The SU S650-XL is rated at 97A, making it harder and more wear-resistant than the standard SU S650. They are physically interchangeable, but the XL variant is recommended for high-cycle operations or concrete surfaces where extended tire life is required. Always verify your truck application before switching between them.
Q: What bearing size and type does the SU S650 use?
A: The SU S650 uses a 1.938 inch inside diameter bore that typically accommodates standard industrial ball or roller bearings. Verify your specific truck model documentation for exact bearing part numbers and preload specifications, as bearing selection depends on axle configuration and load class. The 2.0467 inch bore outside diameter provides the mounting surface.
Q: How do I diagnose worn SU S650 wheels?
A: Signs of wear include visible flat spots or chunks missing from the tread, increased noise or vibration during operation, and reduced steering response. Measure the wheel diameter at multiple points; wear exceeding 0.25 inches below nominal 5.000 inches indicates replacement is needed. Check for bearing movement by spinning the wheel by hand; excess play suggests worn bearings, not just the wheel.
Q: What load capacity should I expect from an SU S650 wheel?
A: Load capacity depends on the truck class and axle configuration. The SU S650 is designed for light to medium duty electric lift trucks. Consult your truck documentation for the axle load rating, typically ranging from 500 to 1500 pounds per wheel. Exceeding rated load or operating on unsuitable surfaces accelerates polyurethane degradation and bearing failure.
Q: How often should SU S650 wheels be replaced?
A: Lifespan varies based on operating conditions. In standard warehouse environments, expect 2000 to 4000 operating hours. Rough concrete or outdoor surfaces reduce life to 1000 to 2000 hours. Inspect wheels monthly for tread wear, cracks, or separation. Replace when tread depth is below 0.5 inches or visible damage appears. Regular wheel rotation between front and rear positions extends overall lifespan.
