Cam Follower Eccentric Models CFH-AB Model CFH-AB
Because there is an eccentricity of 0.25 to 1.0 mm between the mounting shaft of the stud and the stud head, slight positioning adjustments can easily be made simply by rotating the stud. This eliminates the need to align the cam follower with the cam groove or perform precision machining on the mounting hole, greatly reducing the time and labor required for machining and assembly.
Model CFH-A: Equipped with grease nipple and hexagonal sockets.
Basic load rating kN with cage: Basic dynamic load rating 7.87 to 45.4 / Basic static load rating 9.79 to 87.6
Basic load rating kN full rollers : Basic dynamic load rating 13.4 to 67.6 / Basic static load rating 19.8 to 145
