Roller composition

01st April 2020

The unpowered conveying roller, also called free roller, is composed of a cylinder, a shaft core, a deep groove ball bearing, and a bearing mounting frame. It is used for auxiliary rolling during use. It has no power and rolls by external force.

Driven roller generally refers to a motorized roller with a built-in motor. Here we also refer to a roller with a sprocket, timing belt, etc. that can be driven by a reduction motor. The structure is basically the same as that without power, except that the built-in motor or externally installed sprocket or timing belt and other components can be driven by the reduction motor.
