Frequently Asked Questions
Q: What is the difference between SU S994 and SU S994-A?
A: SU S994 is the wheel only (5x3 polyurethane tread on a bare core). SU S994-A is the complete assembly, which includes the machined steel hub, sealed ball bearings, and assembled wheel. If you need just the wheel replacement without hubs or bearings, order SU S994. If you need a ready-to-mount assembly, order SU S994-A.
Q: Will SU S994 fit my electric lift truck?
A: SU S994 fits any electric lift truck requiring a 5.00 inch diameter by 3.00 inch width polyurethane wheel in the standard wheel position. Verify your trucks wheel mounting dimensions before ordering. Check the hub diameter and axle configuration to confirm compatibility with your existing hubs and bearings.
Q: What surface conditions is the SU S994 polyurethane tread rated for?
A: The SU S994 features high-durability polyurethane tread designed for smooth operation on standard warehouse and factory floors. It provides impact and abrasion resistance for general material handling. For wet floors and cold storage environments, contact us about high-traction polyurethane wheel options.
Q: Can I install SU S994 without pressing off the old wheel?
A: No. The SU S994 wheel must be pressed onto your existing hub using a proper wheel press. Do not attempt to hammer or force the wheel onto the hub, as this can damage the bearing seals and hub. A machinist or material handling technician can perform this replacement in 30 minutes or less per wheel.
Q: What is the load rating for a truck equipped with SU S994 wheels?
A: The SU S994 wheel itself does not carry the load rating. Load capacity is determined by your lift trucks frame, battery, and drive system. A single 5x3 polyurethane wheel is commonly used on trucks rated for 4,000 to 6,500 pounds capacity. Refer to your trucks manufacturer nameplate for exact capacity specifications.
Q: How long does a SU S994 wheel typically last?
A: Polyurethane wheels normally last 2 to 4 years in standard warehouse service, depending on floor conditions, load weight, and hours of operation. Check wheels monthly for uneven wear, flat spots, or chunks missing from the tread. Replace when tread wear exceeds 50 percent or when wheels begin to drift or pull to one side during operation.
