Frequently Asked Questions
Q: What does the A suffix on SU 9 X 5 X 5-SF-P-A mean, and how does it differ from the base part SU 9 X 5 X 5-SF-P?
A: The A suffix indicates assembly with integrated hub. The SU 9 X 5 X 5-SF-P-A arrives as a complete pre-mounted wheel: polyurethane tire bonded and press-fitted to a steel hub. You can install it directly on the truck axle without additional pressing or assembly work. The base SU 9 X 5 X 5-SF-P is the tire only and requires separate hub mounting using a shop press. If you lack in-house pressing capability or need immediate deployment, order the SF-P-A assembly.
Q: Is the hub on the SU 9 X 5 X 5-SF-P-A steel or aluminum, and what is the bore diameter?
A: The hub is carbon steel with a machined finish and 5-inch bore diameter. Steel hubs are standard for most industrial lift trucks and provide good strength and corrosion resistance in typical warehouse environments. The machined finish allows precise fit onto tapered roller bearings and axle bushings. Hub material cannot be substituted; if your truck requires an aluminum hub for specific weight or thermal reasons, contact technical support or order custom components separately.
Q: Can I reuse or remount the tire from a worn SU 9 X 5 X 5-SF-P-A assembly onto a new hub?
A: No. The polyurethane tire in the SF-P-A is permanently bonded to the steel hub during manufacturing using adhesive and thermal press processes. Attempting to separate the tire from the hub will destroy both components. When the tire reaches end of life, you must replace the entire assembly as a unit. Do not attempt to separate, re-press, or salvage the tire or hub individually as this will result in unsafe and non-compliant equipment.
Q: What is the proper installation procedure for the SU 9 X 5 X 5-SF-P-A assembly on the truck axle?
A: The SU 9 X 5 X 5-SF-P-A mounts directly onto the truck axle using existing mounting hardware (typically a tapered roller bearing, snap ring, and axle nut or bolt). Clean the axle bore and verify bearing condition before installation. Slide the assembly onto the axle, install the bearing and retaining snap ring, and torque the axle nut to the truck manufacturer specification (typically 60 to 120 foot-pounds depending on truck model). Do not over-torque, as this will damage the bearing and cause premature tire failure. Verify free rotation after installation.
Q: What is the maximum load capacity and speed rating for the SU 9 X 5 X 5-SF-P-A assembly?
A: Load capacity is approximately 1800 to 2000 pounds per wheel depending on truck frame and suspension design. Do not exceed the truck manufacturers specified load capacity regardless of tire rating. Maximum safe operating speed is 12 mph continuous; exceeding this creates heat in the polyurethane compound and accelerates aging and cracking. For heavy-load or high-cycle operations, maintain travel speed below 10 mph to extend tire life.
Q: How long is the typical service life of the SU 9 X 5 X 5-SF-P-A assembly, and when should I plan replacement?
A: In standard warehouse operation (16 to 20 hours daily, moderate load profiles), expect 24 to 36 months of service life. High-cycle intensive use (24-hour operation, heavy loads, frequent acceleration and braking) may reduce life to 12 to 18 months. Check tire condition every 6 months; replace when thickness falls below 0.375 inch, visible cracking develops, or the compound becomes brittle. Polyurethane hardens with age; if the assembly is over 4 years old even with minimal wear, replace it to prevent unexpected in-service failure during operation.
