Frequently Asked Questions
Q: What is the SU S445 and what equipment does it fit?
A: The SU S445 is a load wheel designed for electric lift trucks. Specific fitment details and compatible truck models are available through cross-reference lookup. Contact technical support with your truck model and serial number for exact compatibility.
Q: Is SU S445 different from SU S445-A?
A: Yes. The SU S445 is a wheel only, while the SU S445-A is a complete load wheel assembly that includes the wheel, hub, and bearing components pre-assembled. Use SU S445-A if you need a ready-to-install assembly; use SU S445 if you are replacing only the wheel tread.
Q: What material is the SU S445 wheel made from?
A: The SU S445 uses polyurethane tread material (typically Cushothane XL at 97A durometer) bonded to an aluminum or steel hub. Polyurethane reduces floor damage, decreases noise, and provides better load distribution than steel wheels.
Q: How do I install the SU S445 wheel if I only have the wheel without the assembly?
A: You must have an existing hub and bearings on your truck spindle. Slide the SU S445 wheel onto the spindle and secure it using the original fasteners (usually a nut or bolt through the bore). Ensure the wheel rotates freely and sits flush against the hub. If you do not have an existing hub, order the SU S445-A assembly instead.
Q: What are equivalent part numbers for the SU S445?
A: Cross-reference and equivalent part numbers vary by truck brand. Common OEM equivalents include Superior Tire and Raymond brand wheels. Verify the exact bore diameter and width with your truck manual before ordering a substitute to ensure fitment.
