The bearing pads comprise of a lowfriction laminate of PTFE bonded to an elastomer pad, sliding on a mirror finish material.
The shutter is a high density polyethylene material.
The bearings are set equidistantly in a shutter of the same thickness.
The bearing plate is then placed over the bearing and shutter.
The bearing is then taped all round to prevent the ingress of any dirt and / or slurry.
