Frequently Asked Questions
Q: What is the difference between BA AW-4-1-XL and the standard BA AW-4-1?
A: The BA AW-4-1-XL uses Poly XL polyurethane with 97A Shore hardness, compared to standard Durarun 95A. The higher durometer (97A vs 95A) provides increased wear resistance and reduced compression set, extending wheel lifespan in high-cycle applications.
Q: Which Baker electric lift trucks does the BA AW-4-1-XL fit?
A: The BA AW-4-1-XL replaces BABKAW-4-1-XL, supersedes BKBKAW-4-1-XL, and is equivalent to BABKAW41XL and BKBKAW41XL. Confirm mounting configuration and wheel diameter match your truck before ordering.
Q: Why choose Poly XL 97A over standard Durarun 95A?
A: Poly XL 97A hardness is specified for high-volume material handling operations, concrete and industrial floors, and heavy-load service. The firmer compound reduces wheel deflection, improves steering response, and extends service life in demanding environments.
Q: How long will the BA AW-4-1-XL wheel last compared to standard wheels?
A: Poly XL 97A typically extends lifespan 20 to 40 percent longer than standard 95A polyurethane under comparable service conditions. Expected life ranges from 2000 to 4500 operating hours depending on load, floor conditions, and maintenance practices.
Q: Is the BA AW-4-1-XL suitable for wet floors or cold storage?
A: Poly XL 97A maintains good traction on wet and dry floors. However, for extended cold storage below 20 degrees Fahrenheit, specialized cold-compound formulations provide superior grip. Standard Poly XL 97A hardens in freezer environments; verify application requirements before selecting.
Q: What does superseding mean for the BA AW-4-1-XL?
A: The BA AW-4-1-XL supersedes BKBKAW-4-1-XL, meaning it is the current production replacement for the older part number. Superseding parts provide improved specifications or manufacturing processes while maintaining fit and function compatibility.
