THK Co., Ltd. CF12-1UUR Stud-Type Cam Follower Bearing

Description:

The THK CF12-1UUR Cam Follower is a stud-type cam follower bearing designed to support high radial loads while providing smooth rolling motion in cam mechanisms and linear guide applications. It features a crowned outer ring and double seals to reduce friction, protect against contaminants, and extend bearing service life in demanding industrial environments. Commonly installed in packaging machinery, conveyors, automated production equipment, machine tools, and material handling systems. Maintenance teams and machine builders use this cam follower for equipment repair, replacement, and new machine construction.

Applications:

The THK CF12-1UUR belongs to the THK CF Series of stud-type cam followers. The base model CF12-1 features an enlarged 32 mm outer diameter with an M12 × 1.5 stud thread for higher load capacity than the standard CF12. The suffix "UU" indicates double seals for improved protection against dust and contaminants, while the suffix "R" designates a crowned (spherical) outer ring that helps accommodate slight mounting misalignment and reduces edge loading. These features make the cam follower suitable for guide roller applications in automated machinery, cam mechanisms, conveyors, and transfer systems.
