Frequently Asked Questions
Q: What is the -306 designation on the CR 310125-306?
A: The -306 suffix indicates the specific polyurethane compound formulation used in this wheel. Compound 306 is an OEM Crown specification rated at 97A Shore A hardness, engineered for heavy-duty warehouse and lift truck applications.
Q: What are the complete dimensions of the CR 310125-306 triple load wheel?
A: The CR 310125-306 triple load wheel has a 3.25 inch outer diameter, 2.00 inch tread width, and a 2.047 inch bearing bore diameter. This configuration is designed for load distribution across three wheels on a single axle.
Q: Which Crown lift truck models use the CR 310125-306?
A: The CR 310125-306 is compatible with select Crown electric pallet jacks and lift trucks designed for triple load wheel configurations. Verify your equipment model number against the Crown 154840-30 OEM specification before ordering.
Q: What advantages do triple load wheels provide compared to single wheels?
A: Triple load wheels distribute weight across three contact points, reducing per-wheel load and extending wheel life. They also prevent coning and flat spotting, maintain better traction on uneven surfaces, and are preferred for heavy-duty and long-run warehouse operations.
Q: Is the CR 310125-306 suitable for wet, metal chip, or dock board environments?
A: The 97A compound is durable on metal chips and dock boards, but for consistent performance on wet floors, a high-traction polyurethane variant is recommended. The standard 306 compound is engineered for demanding warehouse conditions including dock operations.
Q: Does the CR 310125-306 come with greaseable bearings?
A: The CR 310125-306 is a wheel only without bearings included. For a complete assembly with greaseable bearings, order the CR 310125-306-88, which includes the bearing assembly and all necessary hardware.
