More Information
Summary:Mini-roller shafts are provided at opposite ends with resilient traction sleeves and with oversized transport sleeves therebetween. Bearing members are provided to position the traction sleeves for frictional engagement with endless drive members extending along opposite sides of the conveyor module. Each bearing member is provided with a relatively enlarged roller shaft-receiving opening that permits limited radial movement of the shaft, and some of the bearing members include a transport sleeve-receiving cradle. Accordingly the roller shaft is able to be deflected or displaced when the concentration or weight of the articles being conveyed on a given area of the conveyor reaches a point where reduction of pressure between the articles is desirable.
