INA/FAG - 2307K-C3-FAG - Header Bearing 2307K C3 Claas 239126.0

This bearing supports the cutterbar drive shaft in the header of a combine harvester. It is a self-aligning double-row spherical roller bearing with a tapered bore and a C3 internal clearance, allowing it to accommodate shaft misalignment and thermal expansion during operation. The bearing sits in the housing that transfers rotational force from the drive input to the knife-drive assembly; a worn bearing produces excessive play that leads to uneven cutterbar motion and increased vibration in the drive train. As an original-manufacturer component, it is ground to the same raceway geometry and clearance specification as the bearing it replaces, so no shimming or housing modification is needed during installation.
