Frequently Asked Questions
Q: What are the dimensional specifications of the YL 504449731 load wheel?
A: The YL 504449731 features a 3.25 inch diameter by 4.50 inch width configuration. This size is standard for many Yale electric pallet jack models and provides optimal load distribution in warehouse and distribution environments.
Q: What is the polyurethane hardness rating for this wheel?
A: The YL 504449731 is manufactured with 95A durometer polyurethane construction. This hardness specification provides solid wear resistance while maintaining adequate flexibility for floor grip during turning and load transfer operations.
Q: Does the YL 504449731 come fully assembled with bearings and hardware?
A: Yes. The YL 504449731 complete assembly includes precision bearings, load-rated axle shaft, grease fitting, and mounting hardware ready for installation on compatible Yale lift trucks. All service components are pre-assembled.
Q: What cross-reference part numbers are equivalent to the YL 504449731?
A: The YL 504449731 is cross-referenced as YL504449731A and YT 504449731-A. An extended-life variant YL 504449731-XL-A is available with upgraded 97A durometer specification for more demanding applications. Verify your equipment requirement before selecting between standard and extended-life versions.
Q: How does the 95A durometer compare to the 97A extended-life variant?
A: The standard YL 504449731 at 95A Shore A is slightly softer, offering balanced performance in typical warehouse operations. The extended-life YL 504449731-XL-A at 97A durometer provides increased wear resistance and load capacity for high-cycle or severe-duty applications. Select based on your specific usage intensity and floor conditions.
