Frequently Asked Questions
Q: What does the XL designation mean on the KA 74879331-XL?
A: The XL designation indicates two features: XL 97A durometer hardness compound and XL3 bond technology. The 97A compound is harder than standard 95A, providing superior cut and tear resistance. The XL3 bond technology enhances durability of the polyurethane-to-steel core attachment.
Q: What are the dimensions of the KA 74879331-XL?
A: The KA 74879331-XL has a 5 inch outer diameter and 2.875 inch tread width (also written as 2-7/8 inch). The hub width and core specifications match standard configurations for electric pallet truck load wheels. Verify these dimensions against your existing wheel or equipment specs before ordering.
Q: How does the 97A durometer compare to standard 95A load wheels?
A: The 97A compound is significantly harder than 95A, resulting in better resistance to cuts, tears, and punctures from sharp objects. This makes the KA 74879331-XL better suited for high-duty-cycle warehouse operations or environments with abrasive or contaminated floors.
Q: What is the XL3 bond technology and why does it matter?
A: XL3 bond technology is a proprietary adhesive and mechanical bonding system that attaches the polyurethane tread to the steel core. Superior bond strength reduces the risk of tread separation from the wheel core, extending wheel life and improving safety in high-duty applications.
Q: Which electric lift truck models are compatible with the KA 74879331-XL?
A: The KA 74879331-XL fits electric pallet trucks and lift trucks from Komatsu, Crown, Toyota, Raymond, Yale, and other OEM manufacturers using 5 inch, 97A durometer load wheels. Confirm your equipment model, serial range, and existing wheel dimensions match before purchase.
Q: What is the service life of the KA 74879331-XL in high-duty applications?
A: In high-duty-cycle warehouse applications, the KA 74879331-XL typically provides 18 to 30 months of service life due to superior durometer hardness and XL3 bond technology. Lifespan extends beyond standard 95A wheels in environments with heavy load cycling, sharp debris, or abrasive floors.
