POLY AND STEEL LOAD WHEEL
Frequently Asked Questions
Q: What is the difference between the poly wheel and steel wheel in the SU S10211?
A: The SU S10211 combines a polyurethane tread bonded to a steel hub. The polyurethane provides grip, noise damping, and floor protection. The steel hub offers structural strength and load distribution. This hybrid design extends tire life compared to solid urethane wheels and reduces vibration compared to steel wheels. Verify the poly thickness with your supplier; some wear applications may have thinner urethane.
Q: Does the SU S10211 work with sealed or open bearing assemblies?
A: The SU S10211 wheel itself is bearing-agnostic and fits both sealed and open bearing setups. However, sealed bearings are strongly recommended for warehouse use to prevent contamination and water ingress. Open bearings require monthly inspection and relubrication with lithium grease. If your truck has open bearings, switch to sealed bearing assemblies to reduce maintenance and extend wheel life.
Q: What symptoms indicate the SU S10211 polyurethane tread is worn out?
A: Inspect the polyurethane tread depth visually; it should be at least 0.5 inches thick. Worn poly shows uneven wear patterns, flat spots, or shiny glazed areas indicating inadequate grip. The wheel may also slip on smooth floors or make a squealing noise when cornering. Tread depth below 0.25 inches significantly increases stopping distance and requires replacement to maintain safety and braking performance.
Q: What is the maintenance schedule for the SU S10211?
A: If installed with open bearings, grease every 30 to 60 days with lithium NLGI 2 grease. If installed with sealed bearings, no periodic lubrication is needed. Monthly: inspect for debris buildup, poly damage, and bearing play. Quarterly: clean poly tread of oil and dirt to restore grip. Do not apply harsh solvents; warm soapy water and a soft brush are sufficient. Store wheels indoors to prevent UV degradation of the polyurethane.
Q: Can the SU S10211 be used in high-speed or outdoor applications?
A: The SU S10211 is designed for standard warehouse speeds up to 8 mph. Higher speeds cause excessive tread wear and heat buildup. Outdoor or dock use exposes the polyurethane to UV damage, temperature swings, and moisture, reducing tread life to 6 to 12 months. For outdoor service, select a UV-stabilized polyurethane wheel or use steel-only wheels. Continuous moisture exposure will cause the poly-to-steel bond to weaken and separate.
