3057042Z Double Row Metal Shielded Cam Roller Cylindrical Outer 20x52x20.6mm

Cam Rollers: Are special variants of deep groove ball bearings which have thicker outer races to allow for running in tracks as rollers where misalignment and shock loads may be present. They have the same characteristics as normal deep groove ball bearings, generally have seals although some unsealed versions are available and can also be used in place of standard bearings. They are available with parallel outside diameter or crowned (spherical) for applications where greater misalignment needs to be catered for.
Benefits: Tolerate high loads, shock loads, misalignment when running in tracks
