Frequently Asked Questions
Q: What is the difference between SU 850 and SU 850-XL load wheels?
A: The SU 850 designation refers to the standard load wheel in the 850 series. The SU 850-XL variant features a polyurethane tread bonded to a steel core with enhanced durability specifications. The XL version typically offers improved wear resistance and load capacity compared to the base SU 850. Verify your equipment requirements before ordering to ensure you receive the correct variant. Using the wrong variant may result in premature wear or poor performance.
Q: Can the SU 850 wheel be used on both pallet jacks and electric lift trucks?
A: Yes, the SU 850 load wheel is engineered for use on both manual pallet jacks and electric lift trucks. Verify the wheel bore diameter and axle shaft size match your equipment before installation. Electric lift trucks typically run higher speeds and may produce more heat, so monitor wheel condition more frequently in electric applications. Pallet jacks place static load on wheels, which may cause different wear patterns than dynamic electric truck use.
Q: What polyurethane tread specifications does the SU 850 have?
A: The SU 850 uses a premium-grade polyurethane tread bonded to a steel core for long wear life and floor grip. Polyurethane compounds resist oils, chemicals, and moisture better than rubber, making them ideal for loading dock and warehouse floors. The tread hardness and thickness are optimized for standard pallet jack loads of 2000 to 5000 pounds per wheel. Do not expose the wheel to extreme heat or direct sunlight for extended periods, as this can degrade the polyurethane bond.
Q: How do I know if my SU 850 wheel needs replacement?
A: Inspect the tread depth monthly. If polyurethane tread is worn smooth or shows visible wear grooves less than 1/16 inch deep, replace the wheel. Look for bonding failure where the polyurethane separates from the steel core. If the wheel makes squeaking or grinding noise, the bearing may be failing. Test the wheel by rolling the jack by hand; if it feels rough or does not roll freely, replacement is needed. Continued use of a worn wheel reduces steering control and increases frame strain.
Q: What is the installation process for replacing a worn SU 850 wheel?
A: Lower the jack or truck to the ground. Use a lifting device to raise the wheel end off the floor. Remove the cotter pin or retaining nut from the axle shaft. Slide the old wheel off the axle. Clean the axle bore and shaft of debris. Slide the new SU 850 wheel onto the axle, ensuring it seats fully. Reinstall the cotter pin or retaining nut and lock it securely. Spin the wheel by hand to confirm it rotates freely. Test the jack or truck movement before placing it back into service.
