Frequently Asked Questions
Q: What equipment is the SU 9141-XL load wheel designed for?
A: SU 9141-XL is an aftermarket polyethylene XL 97A load wheel assembly for electric pallet jack applications. It is suitable as a direct replacement for stock load wheels in industrial material handling equipment. No OEM part numbers are documented for this assembly, so verify fitment by measuring the original wheel bore diameter and width before ordering.
Q: Why choose polyethylene XL 97A instead of standard polyurethane wheels?
A: SU 9141-XL polyethylene XL 97A formulation provides higher hardness (97A vs. 95A) for extended durability on rough or abrasive floors. Polyethylene compounds resist cracking and wear longer than standard polyurethane in high-friction environments. Trade-off is less cushioning and slightly reduced grip on very smooth surfaces.
Q: What are the bore specifications for SU 9141-XL installation?
A: SU 9141-XL has an inside diameter of 1.938 inches, bore outside diameter of 2.0467 inches, and bore depth of 1.43 inches. Verify these dimensions match your axle and hub before installation. The 20mm axle bore is standard on many electric pallet trucks, but confirm your equipment specifications.
Q: How long does an SU 9141-XL wheel assembly typically last in service?
A: Service life depends on floor conditions, load weight, and operating hours. SU 9141-XL polyethylene XL 97A typically lasts 1 to 3 years in high-use warehouse environments with rough floors. Inspect wheels monthly for wear, cracking, or flat spots. Replace immediately if tread depth is less than 0.25 inch or if cracks are visible.
Q: Can I mix SU 9141-XL with other wheel types on the same pallet jack?
A: No. All load wheels on a pallet jack must be the same diameter, width, hardness, and material to maintain level load distribution and handling. Mixing different wheel types can cause uneven wear, steering problems, and safety hazards. Replace all four wheels as a set when you upgrade to SU 9141-XL.
