Frequently Asked Questions
Q: What are the key dimensions of the CR 81645-020 load wheel?
A: The CR 81645-020 features a 5-inch outside diameter, 4.12-inch tread width, and 2.44-inch inside bore diameter. These dimensions are critical for fitment; verify your equipment specifications match before ordering.
Q: What is the wheel construction of the CR 81645-020?
A: The CR 81645-020 Durarun 95A features a polyurethane tread compound bonded to a high-strength steel core. The integrated shoulder bearing provides lateral support and reduces bearing assembly complexity during installation.
Q: Which equipment brands is the CR 81645-020 compatible with?
A: The CR 81645-020 is a Crown OEM part. It may fit other electric pallet jacks and lift trucks with matching bore and diameter specifications from Toyota, Raymond, Yale, or similar brands, but verify dimensions and bearing configuration to ensure compatibility.
Q: How does the CR 81645-020 perform in high-volume warehouse operations?
A: The polyurethane 95A compound is designed for demanding material handling use. The 4.12-inch tread width provides stable rolling and load distribution. Performance depends on floor conditions, load weights, and operating hours; inspect regularly for wear.
Q: What is the lifespan expectancy for the CR 81645-020?
A: Lifespan varies with application intensity. High-traction environments and rough floors accelerate wear. Replace when tread becomes unevenly worn, develops flat spots, cracks appear, or traction is significantly reduced.
Q: Does the CR 81645-020 work on wet or slippery floors?
A: The standard polyurethane compound provides adequate grip for typical environments. For consistent operation on wet floors or cold storage below 32 degrees, confirm the compound specification is suitable for your specific temperature and moisture conditions.
