Frequently Asked Questions
Q: What are the dimensions of the SU S143 load wheel?
A: The SU S143 has an outside diameter of 4.00 inches, side-to-side width of 2.75 inches, inside diameter of 1.875 inches, and bore depth of 0.812 inches. The hub width matches the tread width at 2.75 inches, and the bore outside diameter is 2.4404 inches, making it compatible with standard 5/8 inch axles.
Q: What is the Shore hardness rating of the SU S143 polyurethane tread?
A: The SU S143 features polyurethane with a Shore A 70D hardness rating. This is a medium-hardness compound that balances load capacity, floor protection, and durability in high-wear lift truck applications without sacrificing traction or floor compatibility.
Q: Is the SU S143 suitable for high-wear lift truck applications?
A: Yes. The SU S143 is engineered for high-wear electric lift truck environments. The Cushothane XL polyurethane compound and roller bearing provide reliable performance under intermittent heavy duty cycling. It is rated for frequent load handling in warehouses and manufacturing facilities.
Q: What bearing type is included with the SU S143 wheel?
A: The SU S143 assembly includes a roller bearing and assembly hardware. This bearing design supports lateral and radial loads and is sealed to resist dust and moisture. The bearing is non-adjustable and requires no routine maintenance.
Q: How do I diagnose if my SU S143 wheel needs replacement?
A: Inspect the SU S143 for visible tread wear down to the hub, chunks missing from the polyurethane, sidewall cracking, or flat-spotting. Spin the wheel by hand to check for noise, grinding, or roughness that indicates bearing wear. Replace the wheel if tread depth is less than 0.25 inch or if bearing noise is detected.
Q: What is the tread profile of the SU S143 wheel?
A: The SU S143 has a 1/4 inch radius tread profile. This radius provides smooth rolling and reduces edge wear when cornering or turning on hard floors. The profile is designed to protect delicate floor surfaces while maintaining stable load handling.
