Abstract
The invention provides a plastic-sheathed roller, typically a tension roller of plastic for a belt drive. The roller comprises a wheel comprising an inner ring and an outer ring that are connected through radially oriented ribs arranged spaced apart on a periphery and through a central web. The wheel is mounted for rotating through a rolling bearing on a carrier element, while being supported through a running surface on a belt of the belt drive, and injection gates for injection molding are arranged distributed on a lateral surface while being spaced apart angularly non-uniformly from one another.
