Cam Follower Eccentric Models CFH-AB Model CFH-A

Because there is an eccentricity of 0.25 mm 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-AB: Equipped with grease nipple and hexagonal sockets.

Basic load rating kN with cage: Basic dynamic load rating 3.14 to 5.33 / Basic static load rating 2.77 to 6.78
Basic load rating kN full rollers : Basic dynamic load rating 5.1 to 9.42 / Basic static load rating 5.5 to 14.3
Stud diameter (mm) : 5,6,8,10

Notes on dimensional table

Note) THK also manufactures types that have a driver groove and a greasing hole on the head. (Model numbers of types with a driver groove do not include symbol "-A" in the end.) Note) For information on accuracy standards, please refer to Accuracy standards. Those models do not have a greasing hole and cannot be replenished with grease.
Note1) ○: Model CFH5M-A is available only in carbon steel.
Note2) The rotation speed limit value in the table (*) applies to models that have no seal and use grease lubrication. With those models using oil lubrication, up to 130% of this value is permitted. With those attached with seals, up to 70% of this value is permitted.
