Frequently Asked Questions
Q: What does the -EZ designation on the SU S645-EZ indicate?
A: The -EZ suffix denotes a High Traction polyurethane compound for material handling equipment in general applications, wet floors, and cold storage. EZ does not mean easy installation. The Cushothane XL material provides superior grip on slippery surfaces while maintaining durability in low-temperature environments.
Q: What are the exact dimensions of the SU S645-EZ load wheel?
A: The SU S645-EZ features a 4.000 inch outside diameter by 3.625 inch width. The inside bore diameter is 1.875 inches with a 2.0467 inch bore outside diameter and 0.623 inch bore depth. These specifications ensure fitment on standard electric lift truck and pallet jack axle shafts. Always verify bore diameter against your equipment axle shaft before ordering.
Q: What is Cushothane XL material, and how does it perform?
A: Cushothane XL is a high-traction polyurethane elastomer engineered for material handling applications. It provides excellent grip on wet and cold floors while resisting abrasion and cutting. The XL designation indicates premium grade compound formulation with extended durability compared to standard polyurethane treads.
Q: What equipment is compatible with the 4.000 inch by 3.625 inch SU S645-EZ wheel?
A: The SU S645-EZ is designed for electric lift trucks and powered pallet jacks requiring a 4 inch diameter wheel with standard hub width. Verify your equipment OEM documentation for wheel size specifications. Confirm axle shaft diameter, bore type, and mounting pattern match before installation.
Q: How is the SU S645-EZ installed?
A: Remove the axle bolt from your equipment. Slide the old wheel off the axle shaft. Install the SU S645-EZ by sliding it onto the shaft until the bore seats against the hub or shoulder. Reinstall and torque the axle bolt per your OEM specifications, typically 40-50 ft-lbs. Verify smooth rotation with no binding.
Q: When should the SU S645-EZ be replaced?
A: Replace the SU S645-EZ when tread depth visibly decreases, flat spots develop, the wheel becomes hard or brittle, or operation becomes noisy. In typical warehouse use, High Traction polyurethane wheels last 12 to 30 months depending on floor type and load intensity. Cold storage and wet floor environments may extend or reduce service life.
