ROLLER APPARATUS FOR CABLE TRAY

摘要

Disclosed is a roller apparatus for a cable tray. The roller apparatus for the cable tray according to the embodiment of the present invention is separately arranged in the longitudinal direction of the cable tray with a preset interval and reduces the moving frictional resistance of a cable. The roller apparatus for the cable tray includes a roller shaft whose both ends are supported by both sidewalls of the cable tray and a roller body which is rotationally supported on the outer side of the roller shaft. The roller shaft is elastically formed in the axial direction of the roller shaft and is mounted on both sidewalls of the cable tray by corresponding to the width change of the cable tray.
