Frequently Asked Questions
Q: What are the dimensions and specifications of the KO 664206 mast bearing?
A: The KO 664206 mast bearing is a precision hardened steel guide roller with 39.77 mm inner diameter, 96.28 mm outer diameter, and 29.05 mm width. Material is through-hardened bearing steel with polished bearing raceways. These dimensions ensure precise fit in Komatsu and Cascade lift truck mast assemblies.
Q: What lift truck models is the KO 664206 bearing compatible with?
A: The KO 664206 is compatible with select Komatsu and Cascade electric lift truck models. Cross-reference part numbers include MG 208 FFH, MG208FFH, and CA664206. Verify your mast assembly specifications and equipment model before ordering to confirm compatibility.
Q: What is the material composition and finish of the KO 664206 bearing?
A: The KO 664206 is manufactured from through-hardened bearing steel with polished bearing raceways. This hardened steel construction provides durability and precision load support in mast guide applications, reducing wear on lift truck mast assemblies.
Q: What are the cross-reference and equivalent part numbers for the KO 664206?
A: Cross-reference part numbers for the KO 664206 include MG 208 FFH, MG208FFH, Cascade 664206, and CA664206. When ordering replacement bearings, use the exact OEM part number KO 664206 or verified cross-references to ensure correct fitment.
Q: How does bearing wear affect lift truck mast performance?
A: Worn mast bearings cause excessive mast side-to-side movement, uneven load distribution, and accelerated wear on other mast components. Signs of bearing failure include lateral mast drift, binding during raise or lower cycles, and audible grinding. Replace bearings when wear becomes evident to prevent further damage.
