Frequently Asked Questions
Q: What are the dimensions and material specifications of this load wheel?
A: The wheel features a Durarun 95A durometer polyurethane construction. The 95A Shore durometer hardness rating indicates a firm, durable compound engineered for load-bearing performance in electric pallet jack and lift truck applications.
Q: What is included in this complete load wheel assembly?
A: This is a complete factory assembly that includes factory-installed precision bearings, an integrated axle mounting system for secure attachment, and lubrication fittings. The assembly arrives fully configured for direct use.
Q: Which Yale equipment models is this wheel designed for?
A: The YL 504574280-XL-A is engineered for Yale electric pallet jack and lift truck applications. Verify your specific equipment model and serial range against the original parts documentation to confirm compatibility.
Q: What does the -XL-A suffix designation mean?
A: The -A suffix indicates this is a complete factory assembly with all necessary components: precision bearings, axle mounting hardware, and lubrication fittings. This provides an all-in-one replacement solution without needing to source additional hardware separately.
Q: Why is the integrated axle mounting system important?
A: The integrated axle mounting system ensures precise bearing alignment and support, reducing installation variability and extending service life. This design prevents bearing misalignment, reduces vibration, and maintains consistent smooth rolling performance across load conditions.
Q: How often should the wheel bearings be lubricated?
A: Lubrication fittings allow periodic bearing greasing during routine maintenance. Regular bearing lubrication reduces friction, extends bearing life, prevents corrosion, and maintains smooth rotation. Consult your Yale equipment manual for recommended lubrication intervals and approved grease types.
Q: What durometer rating means for wheel performance?
A: The 95A Shore durometer hardness rating indicates a firm polyurethane compound optimized for load-bearing. This hardness level provides excellent wear resistance and durability under sustained heavy use while maintaining grip and smooth rolling characteristics.
Q: Is this a direct replacement for original Yale wheels?
A: Yes, the YL 504574280-XL-A is engineered as a direct replacement for Yale electric pallet jack and lift truck applications using this wheel size and attachment configuration. Always confirm the part number matches your equipment documentation before purchase.
