Frequently Asked Questions
Q: What are the wheel dimensions for the CR 79330-1-ST?
A: The CR 79330-1-ST has an 8-inch diameter and 2-inch tread width. The bore size is 25mm. These dimensions ensure compatibility with Crown PTH50 series manual pallet jacks and similar models using standard steer axle specifications.
Q: What bearing construction does the CR 79330-1-ST use?
A: The CR 79330-1-ST features sealed ball bearing construction. Sealed bearings are pre-lubricated and enclosed to reduce contamination from dust, moisture, and debris, extending bearing life in material handling environments.
Q: What is the tread material of the CR 79330-1-ST?
A: The CR 79330-1-ST uses molded black polyurethane tread. Black polyurethane is a standard, durable compound for general material handling and warehouse applications. It resists wear, oil, and mild chemicals.
Q: Is the CR 79330-1-ST compatible only with Crown PTH50?
A: The CR 79330-1-ST is designed for Crown manual pallet jacks, specifically the PTH50 series. It may also fit other Crown manual pallet jack models with identical steer axle bore and mounting specifications.
Q: Can the CR 79330-1-ST be used in wet or cold storage environments?
A: Standard black polyurethane has reduced grip on wet floors compared to high-traction compounds. For wet or cold storage applications, consider wheels with High Traction polyurethane formulations instead.
