Igus claims that its plastic linear and plain bearings are increasingly replacing metal and roller bearings in the machine-tool sector thanks to their chip-, dirt- and dust-resistant capabilities.

The company’s Drylin linear bearings in particular are designed to repel particles from the contact surface by the movement itself. As there are no rolling elements, such as those found in more conventional roller bearing systems, there is nowhere for chips and dirt to become trapped.

This is said to be especially beneficial for machine tools and their moving parts, such as gliding doors and telescopic covers, because of the arduous environment in which they have to operate.

Key benefits

  • All plastic bearings from Igus are dry running — meaning they do not require any lubrication.
  • The plastic bearings are able to protect against the soiling of grease and oil.
  • The ‘tribo-plastic’ bearings are maintenance free.
  • They are designed to withstand high temperatures.
  • The bearings have low coefficients of friction.
  • Excellent wear resistance is ensured.
  • The bearings are said to absorb very little moisture.

Igus

Igus is the largest producer of reinforced plastic energy chains and injection-moulded polymer bearings. The range of polymer bearings includes Iglidur plain, Igubal spherical and Drylin linear bearings. They offer an excellent price-to-life relationship and are developed under the toughest conditions. They are oil, maintenance and lubrication free, low wear, resistant to dirt and dust, corrosion free and simple to fit. Igus also has the data to precisely predict the lifetime of these bearings within a specific application.

Energy chains are the umbilical cord of modern machines. They minimise downtime and protect, support and extend the service life of cables and hoses. The broad range incorporates more than 30,000 innovative, low-cost products. From the smallest ‘micro’ chain to the largest chain in the world, the E4.350, Igus energy chains are capable of long and short travel distances at high speeds in all axes.

Igus also has its own cable series, Chainflex, specially designed with energy chains in mind. They are highly flexible cables, offering a long service life and very small bending radii. A wide range is available, from small signal cables to large power cables, high-speed data cables and glass fibre-optic cables.

The company’s energy chains and Chainlflex cables can be delivered as a fully harnessed and pre-assembled Readychain system, cutting purchasing, warehousing and installation costs.
