COATED AND SPECIAL ROLLERS
This particular kind of coating consists of an expansible PVC tube which adheres firmly to the roller surface and it is suitable for minimum lengths of 200 mm.
Please consult the technical department of DUGOMRULLI in case that stresses or loads in axial direction are expected.
PV TUBULAR COATING
The grey soft polyvinyl chloride coating (PV) has a smooth surface which resists to chemicals and wear.
Hardness A = 65 Shore at 20°C.Operating temperatures: –10° +40°C.
PG TUBULAR COATING
Black tubular polyvinyl chloride coating with rubber additive (PG) that resists to wear and ageing.
Hardness A = 68 Shore at 20°C. Operating temperatures: –10°C +110°C.
In some cases it is necessary to guide the load units by means of flanges that are applied at the ends or in the middle of the roller tube.
The application is carried out by welding or by mechanical fixing (flange type 501039, see the picture 2).
