Curtain runners are a special device used to facilitate the movement of two bodies in contact with each other. They are built from a body in pressed sheet metal, on which bearings are then mounted which will be used to compose the wheels. These bearings are in carbonitrided and galvanised iron or in acetal resin, respectively for the sheet metal or aluminium guides, sold normally.
The carbonitriding and galvanising processes make it possible to manufacture pieces with a limited thickness, with greater resistance to wear, meshing and corrosion. Therefore, these processes are suitable for all those pieces and surfaces subjected to contact with other moving parts.
Acetal resin, also called polyoxymethylene, is a semi-crystalline thermoplastic material with exceptional characteristics. It can be worked easily, has high mechanical resistance, absorbs minimum amounts of humidity, has excellent resistance to wear and sliding and is remarkably versatile with great elasticity.

The axial movement system provides great fluidity, ideal for use at high temperatures. This kind of device is mainly used for:

  • Truck tarpaulins
  • Sliding uprights in the truck bodies
  • Other types of sliding runners
