igus drylin W T20 linear carriage

With the T20 of the drylin W series, igus has launched a new linear carriage that has the same dimensions as most classic carriages with recirculating ball bearing guides. This enables a quick 1:1 replacement without any structural adjustments. By using drylin W, applications benefit from freedom from lubrication, a long service life, less cleaning effort and reduced weight.

Unlike classic ball circulation systems, the carriage does not roll in linear systems from the drylin W series, but slides quietly over the rail on liners made of high-performance plastic. The new linear carriage T20 is a robust and corrosion-free monoblock made of aluminium with linear plain bearing liners made of iglidur J200 for a long service life on hard-anodised aluminium rails.

The drylin W range is characterised by a high degree of flexibility. This allows users to choose between different rail models. One of the most popular ones is the drylin W standard rail WS-10-40 — a robust hard-anodised and corrosion-free linear rail made of aluminium, characterised by a flat construction and a torsion-resistant double shaft geometry. This has been demonstrated by tests in the igus test laboratory. A linear carriage of the T20 series moved back and forth on a rail length of 1000 millimetres in 24-hour operation — with a load of 250 N and an acceleration of 10 m/s². The system achieved a running performance of 2500 km in completely dry operation. This corresponds to the distance between Munich and Cairo. With a load of 2 kg and a slow travel speed, a running performance of 18,000 km was achieved.

In addition to durability, switching to a linear guide with a liner made of high-performance plastic offers further advantages. Unlike rolling systems, the liner does not require any external lubrication. Integrated, microscopic solid lubricants enable a low-friction dry operation. Eliminating lubricants saves time and costs for maintenance work, while having a positive effect on the life-cycle assessment. The liners can be replaced again and again with little effort. The cleaning effort is also low, as the liner simply pushes the dirt and grime off the rail. In rolling systems, on the other hand, 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.
