igus T20 lubrication-free linear carriage

Click2Contact

The igus T20, part of the drylin W series, is a linear carriage with the same dimensions as most classic carriages with recirculating ball bearing guides. This enables a 1:1 replacement without any structural adjustments. According to igus, by using drylin W, applications benefit from freedom from lubrication, a long service life, less cleaning effort and reduced weight.

The carriage does not roll, but slides quietly over the rail on liners made of high-performance plastic. A robust and corrosion-free monoblock made of aluminium with linear plain bearing liners made of iglidur J200 provides long service life on hard anodised aluminium rails.

Unlike rolling systems, the liner does not require any external lubrication, since integrated, microscopic solid lubricants enable a low-friction dry operation. Cleaning effort is low, as the liner simply pushes the dirt and grime off the rail. In rolling systems there is often the risk that the dirt will combine with lubricating oil to form a mixture that reduces smooth running and increases the risk of contamination.

In addition to the aluminium version, igus has also developed a linear carriage made of stainless steel. In combination with double rails made of VA stainless steel and linear liners, for example made of the FDA- and EU-compliant material iglidur A160, hygienic and cleaning-intensive applications are also possible for the food, medical and pharmaceutical sectors.
