Frequently Asked Questions
Q: What is XL3 bonding technology on the SU 9143-XL-A?
A: XL3 bonding technology refers to an advanced polyurethane-to-steel hub adhesion process that creates a superior bond between the tread and the hub. This prevents tread separation or delamination under heavy shock and cyclic loading, extending wheel life and improving safety in high-demand industrial applications.
Q: What are the SU 9143-XL-A dimensions?
A: The SU 9143-XL-A is 4.000 inches in outside diameter by 2.500 inches in width. The bore depth is 1.43 inches, bore outside diameter is 2.0467 inches, and hub width is 6.5 inches. These specifications are required for fitment verification; confirm compatibility with your electric lift truck frame and axle configuration before installation.
Q: What durometer rating does the SU 9143-XL-A polyurethane use?
A: The SU 9143-XL-A features a 97A Shore A durometer polyurethane tread. This firm hardness rating ensures extended wear life, excellent abrasion resistance, and high load capacity in heavy-duty industrial applications. The 97A compound is optimized for maximum durability in demanding surface conditions.
Q: What bearing configuration does the SU 9143-XL-A include?
A: The SU 9143-XL-A is fitted with pre-pressed precision ball bearings integrated into the steel hub assembly. These sealed bearings are not field-serviceable; when bearing failure occurs, the entire wheel assembly must be replaced. The sealed design minimizes maintenance and extends operational life by excluding dust and moisture.
Q: What equipment is the SU 9143-XL-A designed for?
A: The SU 9143-XL-A is engineered for material handling equipment applications requiring a 4.000 inch diameter x 2.500 inch width load wheel. It is suitable for electric lift trucks and material handling platforms that utilize this wheel size. Verify the cross-reference numbers (SU9143XL, 9143XL, SU 9143 XL) match your equipment nameplate before ordering.
