Frequently Asked Questions
Q: What is the nominal bore size for the SU S9874 load wheel?
A: The SU S9874 features a 20 mm nominal bore to accommodate standard axle shafts found on most class 2 reach trucks. Always verify your trucks axle diameter before ordering.
Q: Why does the Velocity hub design improve wheel life?
A: The Velocity hub design incorporates internal channels and fins that enhance heat dissipation. This reduces tire temperature buildup during high-cycle warehouse operations, extending tire and bearing life by approximately 20 to 30 percent compared to standard hub designs.
Q: What hub material options are available for the SU S9874?
A: The SU S9874 comes in variants with either aluminum or nylon hub cores. Aluminum hubs provide superior heat dissipation and durability. Nylon hubs offer lower cost and reduced weight. Confirm your truck requirement before ordering.
Q: What outer diameter sizes are available for the SU S9874?
A: The SU S9874 is available in outer diameters ranging from 4 to 6 inches. Consult your truck manual or the nameplate on your outrigger assembly to determine the correct diameter for your equipment.
Q: Are the bearings on the SU S9874 sealed or open?
A: The bearings are sealed precision ball bearings. Sealed bearings reduce moisture ingress and require minimal maintenance. Do not attempt to regrease sealed bearings, as this can cause overpacking and failure.
Q: Is the SU S9874 suitable for wet floor or cold storage environments?
A: The standard SU S9874 polyurethane tread performs adequately on dry warehouse floors. For wet floors or cold storage below 32 degrees Fahrenheit, verify with our technical team if a specialized compound is needed to maintain traction and prevent brittleness.
