Frequently Asked Questions
Q: What is Poly XL compound and how does it differ from standard polyurethane?
A: Poly XL is an enhanced polyurethane formulation with a Shore 97A hardness rating, offering increased durability and load capacity compared to standard Shore 95A wheels. XL compound delivers longer tread life in high-cycle pallet truck service and improved performance in demanding material handling environments.
Q: What are the specifications of the CT 1055548-XL?
A: The CT 1055548-XL features a 5.000 inch outside diameter, 3.625 inch width, and 2.441 inch hub bore. The wheel is constructed from Poly XL polyurethane (97A durometer) bonded to a machined steel core, providing superior durability for Caterpillar electric lift truck applications.
Q: What Caterpillar equipment does the CT 1055548-XL fit?
A: The CT 1055548-XL is engineered as a replacement for Caterpillar electric pallet jacks and lift trucks requiring OEM part number 1055548. Confirm your equipment model and serial range match the CT 1055548-XL specification before ordering.
Q: What is the OEM part number this wheel replaces?
A: The CT 1055548-XL supersedes and replaces OEM Caterpillar part number 1055548. Cross-reference numbers include CT 1055548, CT1055548, 1055548, and CT1055548V-THO.
Q: Does Poly XL compound work in cold storage or wet environments?
A: Poly XL is formulated for standard material handling environments. For cold storage or consistently wet floor applications, confirm environmental suitability with product specifications. Extended exposure to freezing temperatures or wet conditions may affect traction and compound flexibility; alternative formulations such as EZ High Traction may be more suitable for those applications.
Q: How long does the CT 1055548-XL last compared to standard Shore 95A wheels?
A: The 97A durometer Poly XL compound typically extends tread life 20-40 percent longer than Shore 95A in comparable high-cycle pallet truck service. Actual lifespan depends on load tonnage, cycle frequency, and floor surface conditions. Regular visual inspection identifies uneven wear or tread degradation signaling replacement timing.
