Frequently Asked Questions
Q: What does the XL designation mean on the CT 1055553-XL?
A: The XL designation indicates this wheel uses Poly XL 97A high-performance polyurethane compound. XL formulations are engineered for maximum cut and tear resistance in the most demanding duty cycles.
Q: How does the CT 1055553-XL compare to the standard CT 1055553?
A: The CT 1055553-XL uses Poly XL 97A (97A durometer) instead of the standard Durarun 95A (95A durometer). The harder 97A polyurethane and XL3 bonding technology provide superior cut and tear resistance, making it suitable for the highest duty cycle applications.
Q: What is XL3 bonding technology?
A: XL3 bonding technology is an advanced adhesive system that secures the polyurethane tread to the steel core. This technology maximizes cut and tear resistance, reducing premature tread separation and extending wheel life in severe duty.
Q: What part numbers does the CT 1055553-XL supersede?
A: The CT 1055553-XL supersedes CT1055553-A and also cross-references to CT1055553 and CT1055553-MIL. If your equipment specifies the older part numbers, the XL version is the upgraded replacement with improved durability.
Q: Are CT 1055553-XL dimensions the same as the standard CT 1055553?
A: Yes. The CT 1055553-XL maintains the same 5.00 inch outer diameter, 2.875 inch tread width, and 2.047 inch bore as the standard version. The upgrade is in polyurethane grade and bonding technology, not physical dimensions.
Q: How much longer does the CT 1055553-XL last compared to standard CT 1055553 wheels?
A: Lifespan depends on duty cycle, load, and floor conditions. The harder 97A compound and XL3 bonding can extend life by 20-40% in high-duty applications compared to standard wheels. In lighter duty, the performance difference may be less noticeable.
