igus has introduced the R4.1-Light series of stable, airtight, lightweight energy tubes developed specifically for tooling machines.

R4.1-Light energy tubes

Users of toolmaking machines face the challenge of having to organise their production under enormous cost-pressure and high-efficiency requirements. The R4.1-Light energy tubes are claimed to provide top chip protection and stability despite weighing 25 per cent less than comparable types.

The first version being released is the R4.38L with an inside height of 38mm; further sizes, with inside heights of 31mm and 48mm, are to follow shortly. Across all sizes, the R4.1-Light energy chains have very smooth interiors.

The matching interior division systems protect the cables from abrasion and wear. The round outer contour of the new cover ensures small gap dimensions and thus a more airtight chain.

Key features and benefits

  • The tubes can be pivoted open on both sides for easier cable assembly
  • They ensure high stability — up to 26kg filling per metre — thanks to an interlocking rear grip for torsion strength
  • They have a double stop system with large stop areas for optimum load distribution.
  • Design of the cover was inspired by RX-tube, which has proved its airtightness: 2.7g chips after 251,900 cycles

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.
