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

The THK CF12-1UUR Stud-Type Cam Follower Bearing is a compact cam follower designed to carry high radial loads while delivering smooth rolling motion in cam mechanisms, conveyors, and linear-guide systems. It combines a 12 mm stud with an M12 × 1.5 thread, based on the CF12-1 base model, with an outer diameter of 32 mm, outer ring width of 14 mm, inner width (B) of 15 mm, overall length (B1) of 40 mm, and thread length (G1) of 13 mm. The outer ring is crowned (spherical) to tolerate mounting misalignment and reduce edge loading, while the double-sealed (UU) construction protects against dust and contaminants with maintained lubrication for longer service life. It is grease-lubricated and manufactured from high-carbon bearing steel, offering a basic dynamic load rating of 7.87 kN and a basic static load rating of 9.79 kN for dependable high-radial-load performance. In practice, the CF12-1UUR supports guide-roller applications in automated machinery, packaging equipment, conveyors, machine tools, and material handling systems, and is commonly used for equipment repair, replacement, and new-machine construction. Common replacements include THK CF12-1, CF12-1R, and CF12-1VUUR.
