Frequently Asked Questions
Q: What are the dimensions of the CR 310227-3-A load wheel assembly?
A: These precision dimensions ensure tight tolerances for secure mounting on Crown electric lift truck load wheel shafts.
Q: What is the Shore A hardness rating for the CR 310227-3-A?
A: The CR 310227-3-A polyurethane wheel has a Shore A 95A hardness rating. This premium hardness level balances load support capacity with wear resistance for continuous duty material handling without excessive compression or deformation.
Q: What equipment does the CR 310227-3-A fit?
A: The CR 310227-3-A is engineered as a direct replacement for Crown electric pallet jacks and lift trucks equipped with triple load wheel configurations. Verify your equipment model supports triple load wheel setup and that bore specifications match before ordering.
Q: Why is polyurethane preferred for load wheels?
A: Polyurethane provides superior wear resistance, load capacity, and durability compared to alternative wheel materials. The precision-machined surfaces of the CR 310227-3-A maintain tight tolerances throughout extended duty cycles, ensuring consistent performance in warehouse material handling operations.
Q: How should the CR 310227-3-A be stored when not in use?
A: Store the wheel in a cool, dry location away from direct sunlight and extreme temperatures. Protect from oils, solvents, and chemical exposure to preserve the polyurethane material and maintain dimensional integrity.
Q: What is the service life expectancy of the CR 310227-3-A?
A: Service life depends on operating conditions, load weight, and frequency of use. Polyurethane wheels of this grade typically provide extended service life in continuous duty applications. Inspect periodically for wear patterns and replace when tread wear becomes significant or bore tolerances degrade.
