Frequently Asked Questions
Q: Is SU 9149-EZ the same as SU 9149-EZ-A?
A: SU 9149-EZ and SU 9149-EZ-A are two separate SKUs. SU 9149-EZ is the standard designation. Verify which SKU your truck documentation specifies before ordering. Do not assume they are interchangeable without confirming bore diameter, width, and overall dimensions match your axle specifications.
Q: What is the durometer rating and material composition of SU 9149-EZ?
A: SU 9149-EZ features 95A durometer polyurethane tread material. This hardness grade provides a balance between wear resistance and floor grip. 95A is lighter than the 97A found in higher duty cycle assemblies, making it suitable for standard intensity pallet truck applications rather than extreme surface conditions.
Q: What load and floor conditions is SU 9149-EZ rated for?
A: SU 9149-EZ is designed for standard pallet truck applications on smooth to moderately rough concrete floors. It is not recommended for high duty cycle operations, extreme surfaces, or environments with heavy debris. Maximum load capacity depends on the lift truck frame specifications, not the wheel assembly itself. Consult your trucks nameplate for load rating.
Q: How do you diagnose if SU 9149-EZ wheels need replacement?
A: Inspect wheels quarterly. Replace SU 9149-EZ if you observe: flat spots or uneven wear patterns, chunks or chunks missing from the tread, visible cracks in the polyurethane, separation between the polyurethane and the wheel core, or reduced steering response and increased steering effort. These are signs the wheel cannot maintain grip or load capacity.
Q: What is the installation procedure for SU 9149-EZ?
A: Lift the truck and secure it on jack stands. Remove the cotter pin or axle bolt from the old wheel. Slide the wheel off the axle. Clean the axle with a cloth to remove dirt. Align SU 9149-EZ bore with the axle and slide it on. Install the axle bolt or cotter pin and secure. Verify the wheel spins freely and does not rub the frame. Lower the truck and test operation.
Q: How should SU 9149-EZ wheels be maintained?
A: Clean wheels weekly with water to remove salt, sand, and chemical spills that degrade polyurethane. Dry with a cloth. Do not use bleach, acetone, or petroleum solvents. Inspect the bore monthly for metal shavings or damage. If the axle is bent or has burrs, sand them smooth before installing a new wheel. Rotate wheels if one side shows more wear than others. Expected maintenance interval: every 3 to 6 months depending on use.
