Cylinder line - Import export

The Rockflon series is a line of structural cylindrical bearings that generally allow rotations of ±2° around only one horizontal axis. They represent an evolution of the roller bearings, in which rotation movements take place through the rolling friction between two steel elements, one flat and the other a cylindrical rocker so that contact occurs along the cylinder generator line. The mutual sliding of 2 plane surfaces, one of stainless steel and the other of PTFE, ensures the bearing's translation movements. The use of Rocklon bearings is recommended whenever a high degree of stiffness against transverse rotations is considered necessary, a characteristic also typical of the series. Their elongated rectangular shape along the rotation axis is especially suitable if there is limited space available in the perpendicular direction to the rotation axis. Rockflon bearings are classified by two letters that have the following meaning: KF = Fixed Rockflon Bearing KU = Longitudinally guid
