Frequently Asked Questions
Q: What is the wheel diameter and material composition of this steer wheel?
A: The CR 79330-1 features an 8 inch diameter wheel with red ultra polyurethane tread, a 2 inch wide machined steel hub, and precision sealed bearings. This combination provides durability and smooth steering for manual pallet jack applications.
Q: Which manual pallet jack models use this steer wheel assembly?
A: The CR 79330-1 is engineered for Crown PTH and PTH50 series manual pallet jacks. PTH50 refers to a 5,500 pound capacity model. Verify your equipment model matches before ordering.
Q: What makes the polyurethane tread material suitable for manual jack steering?
A: Red ultra polyurethane provides excellent grip on concrete and smooth floors, resists oils and chemicals, and maintains consistent steering response over extended use. This material does not degrade from moisture or temperature swings like rubber.
Q: Why is the steel hub design important for this steer wheel?
A: The 2 inch wide machined steel hub provides structural rigidity and load distribution needed to withstand operator steering forces without flexing or warping. Machining ensures precise bearing alignment for smooth rotation.
Q: How long does the sealed bearing on this steer wheel last?
A: Precision sealed bearings are designed to operate for the service life of the manual pallet jack under normal usage. Bearing failure is typically caused by impact damage, lateral overloading, or contamination rather than normal wear. Regular inspection for noise or grinding indicates bearing degradation.
Q: What maintenance is needed for this steer wheel assembly?
A: Keep the polyurethane tread clean and free of debris. Inspect the hub bolts for tightness. Monitor bearing operation for unusual noise or drag. The sealed bearing design eliminates the need for lubrication, reducing maintenance requirements.
