Frequently Asked Questions
Q: What are the specifications of the KO 49910-1 bearing?
A: The KO 49910-1 is a 25mm plain bearing manufactured from case-hardened bearing steel with a precision ground surface finish. It is engineered as a rotational support component for wheel or axle assemblies in Komatsu electric lift trucks and is designed for press-fit installation.
Q: Which electric lift truck models require the KO 49910-1 bearing?
A: The KO 49910-1 is designed for Komatsu electric lift truck components. It serves as a direct replacement bearing in load wheel and support assemblies within compatible Komatsu electric lift truck models. Verify your equipment model number and application before ordering to confirm compatibility.
Q: What material is the KO 49910-1 bearing made from and why?
A: The KO 49910-1 uses case-hardened bearing steel with precision ground surfaces. Case-hardening provides a hard outer surface for wear resistance while maintaining a tough inner core for shock absorption. This material composition supports the heavy radial and thrust loads generated by electric lift truck wheel assemblies under load.
Q: How is the KO 49910-1 bearing installed?
A: The KO 49910-1 requires press-fit installation onto the shaft or into the bearing bore. This method ensures a precise, secure fit that prevents rotation or slippage under load. Proper press-fit installation is critical to bearing performance and service life.
Q: What is the difference between the KO 49910-1 and KO 49748-00 bearings?
A: Both the KO 49910-1 and KO 49748-00 are 25mm bearings manufactured from case-hardened bearing steel for electric lift trucks. They are engineered for similar applications within Komatsu electric lift truck load wheel and support assemblies. Confirm your specific equipment model and bearing location to select the correct part number.
Q: What indicates the KO 49910-1 bearing needs replacement?
A: Replace the KO 49910-1 if the load wheel exhibits grinding noise, excessive play or movement on the axle, resistance to rotation, or if visual inspection reveals scoring on the bearing races or surfaces. Worn bearings reduce lift truck performance and increase safety risks.
