Frequently Asked Questions
Q: What is the difference between SU S820, SU S820-XL, and SU S820-XL-A?
A: These are cross-equivalent SKUs for the same load wheel assembly. SU S820 is the standard designation, SU S820-XL indicates the enhanced XL3 bonding technology variant, and SU S820-XL-A is the OEM equivalent part number. All three are compatible with the same electric lift truck applications. Use whichever SKU matches your inventory system.
Q: Is the SU S820 compatible with 20 mm axle mounting?
A: Yes. The SU S820-XL variant is specifically designed for 20 mm axle mounting with an 82 mm wheel diameter. Verify your truck is equipped with a 20 mm axle before ordering. Using an incorrect bore size will result in excessive play or inability to mount.
Q: What core material is used in the SU S820 load wheel?
A: The SU S820 features a CNC machined mild steel core manufactured from SAE 1045 steel. This material provides excellent load capacity, durability, and resistance to fatigue. The steel core is bonded to the polyurethane tread using mechanical interlocking or proprietary bonding agents.
Q: How much load capacity does the SU S820 support?
A: Load capacity depends on the truck model and how many wheels share the load. The SU S820-XL is designed for high-capacity electric lift truck applications. Consult your truck documentation for the rated load per wheel. Exceeding rated capacity will cause premature wear or wheel failure.
Q: Can I use the SU S820 as a replacement for a different wheel brand?
A: The SU S820 can substitute for equivalent wheels from other brands if the bore diameter, wheel diameter, and core material match. Always verify the exact dimensions of both wheels before substituting. A size mismatch will affect truck handling and load distribution.
Q: What is the polyurethane tread hardness for the SU S820?
A: The SU S820 features 95 Shore A polyurethane tread, which provides good grip, wear resistance, and durability for typical warehouse and loading dock environments. This hardness is suitable for most electric lift truck applications. Softer compounds may be needed for cold storage or outdoor use.
