Frequently Asked Questions
Q: What are the dimensions and specifications of the CT NA067018 caster wheel?
A: The CT NA067018 features a 4 inch diameter x 2 inch wide polyurethane tread bonded to a precision machined steel core. Durometer hardness is 95A Shore A, bore size is 0.787 inch, and sealed ball bearings are standard. This wheel is engineered for Caterpillar and Mitsubishi electric lift trucks.
Q: Is the CT NA067018 the same as CT NA067018-SG?
A: Both CT NA067018 and CT NA067018-SG are functionally equivalent Caterpillar OEM specifications. Cross-references include NA067018 and SG-NA067018. Verify your equipment documentation to confirm which suffix version your lift truck requires.
Q: Can the CT NA067018 handle cold storage and wet floor operations?
A: The 95A Shore A polyurethane compound provides moderate traction on wet floors. For consistent cold storage performance below 0 degrees Fahrenheit, the High Traction polyurethane variant (EZ suffix) is recommended for improved grip and reduced cracking.
Q: What load capacity does this wheel support?
A: Load capacity is determined by your complete lift truck assembly and axle configuration, not the wheel alone. Refer to your equipment nameplate or documentation for maximum load rating. Exceeding rated capacity will cause premature bearing failure and core delamination.
Q: How do I know if the CT NA067018 needs replacement?
A: Replace the wheel when tread is worn flat, polyurethane is cracked or chunked, or if you hear grinding noise from the bearing. Visible separation of polyurethane from the steel core indicates imminent failure and unsafe operation.
