Frequently Asked Questions
Q: What are the specifications of the CR 71893-040 load wheel?
A: The CR 71893-040 has a 5.00 inch outside diameter, 4.12 inch tread width, and uses 95 Shore A polyurethane compound molded onto a machined steel core. The bearing bore accommodates axle shafts with 1.181 inch (30 mm) diameter.
Q: What Crown equipment is the CR 71893-040 compatible with?
A: The CR 71893-040 is specifically designed for the Crown WP 3000 platform series electric pallet trucks. It is a direct OEM fit for this platform when the axle shaft meets the 1.181 inch diameter specification.
Q: What bearing type does the CR 71893-040 use?
A: The CR 71893-040 is equipped with shouldered bearings to BS 6006 2RS specification. These sealed bearings provide precision load distribution and protection against contamination, extending operational lifespan under warehouse conditions.
Q: How does the 95 Shore A hardness of the CR 71893-040 compare to other load wheels?
A: The 95 Shore A rating on the CR 71893-040 represents a slightly softer polyurethane than higher hardness ratings, providing improved traction on concrete and smooth floors while maintaining good load-carrying capability. This balance makes it effective for general warehouse pallet jack operations.
Q: Can the CR 71893-040 be used on pallet jacks other than Crown WP 3000 series?
A: The CR 71893-040 is engineered specifically for Crown WP 3000 series equipment. Use on other brands or models requires verification that axle shaft diameter, bearing bore, and overall wheel dimensions match your equipment specifications. Mismatched dimensions will cause improper fitment and operational problems.
