ABSTRACT:
The roller has a fixed overhung shaft (2) with a groove at its overhung end, in which to lodge a snap ring (14), and a shoulder (9) at its anchored end. The roller body (1) is journalled to the shaft (2) via a pair of rolling bearings (4) the inner rings (6) of which are checked axially by the snap ring (14) and the shoulder (9), respectively. An annular bracket (20) shrouds a seal (17) having a frontal lip which rides the bearing (4) nearest the anchored end of the shaft (2); the bracket (20) itself is locked to the shaft in fluid-tight fashion. An outer cover (15) pressed into the outer edge of the hollow body of the roller encases the overhung end of the shaft (2). The roller thus embodied is simple and inexpensive to manufacture.
