Frequently Asked Questions
Q: What are the specifications of the SU S149-XL-A load wheel assembly?
A: The SU S149-XL-A assembly features a 6.00-inch outside diameter, 2.88-inch tread width, and 3.149-inch bore. It uses polyurethane tread bonded to machined steel core with Shore A 95A hardness. Integrated shoulder bearings are included for reliable performance under heavy load and long-run applications. This is an OEM part number designed specifically for electric lift trucks operating in demanding environments.
Q: What is the difference between SU S149-XL and SU S149-XL-A?
A: The SU S149-XL is the wheel only at 4.000 inches outside diameter. The SU S149-XL-A is a complete pre-assembled load wheel assembly with integrated shoulder bearings and comes ready to install. The assembly version has a 6.00-inch outside diameter and 2.88-inch tread width, making it a larger overall package. Choose the assembly version if your truck supports the larger diameter and bore size, as installation is faster.
Q: Can the SU S149-XL-A fit on my current truck?
A: The SU S149-XL-A requires a 3.149-inch bore to fit your axle. The 6.00-inch overall diameter is larger than many standard wheels, so verify wheel well clearance with your truck manual before ordering. The assembly is designed for trucks equipped to handle the larger diameter and the integrated shoulder bearings. Attempting to install on an incompatible truck causes binding or clearance damage.
Q: Is the SU S149-XL-A a direct replacement or does it require modifications?
A: The SU S149-XL-A is a direct replacement if your truck was originally equipped with a 6.00-inch diameter wheel and 3.149-inch bore. No modifications are needed for plug-and-play installation. If you are upgrading from a smaller wheel, verify the larger diameter does not interfere with the truck frame, axle geometry, or brake components. Consult your truck documentation or contact the manufacturer before attempting an upgrade.
Q: What is the maximum load the SU S149-XL-A assembly can handle?
A: The SU S149-XL-A is rated for heavy-load and long-run applications. The Shore A 95A hardness and steel core provide robust load capacity. Exact maximum load depends on total truck configuration and load distribution. Consult your lift truck manual for per-wheel load limits. Do not exceed rated load, as this damages the polyurethane-to-steel bond and accelerates bearing wear.
Q: How do I maintain the integrated shoulder bearings on the SU S149-XL-A?
A: The integrated shoulder bearings require no routine lubrication if sealed. Inspect weekly by lifting the wheel and rotating it by hand, listening and feeling for grinding or roughness. If you hear noise or feel resistance, the bearings are wearing and the assembly should be replaced soon. Do not attempt to repack or adjust integrated bearings, as they are factory sealed. Clean the outside of the assembly to prevent dirt ingress around bearing seals.
