Following a series of representative in-house tests carried out over a period of two years, Igus has announced that its Chainflex CF11 and CF211 series can operate reliably and safely in smaller bending radii.

Chainflex

The permissible bending radius for the CF11 TPE measuring system cable has been reduced by 32 per cent from 10x diameter to 6.8xd, and that of the CF211PVC variant by 25 per cent from 10xd to 7.5xd.

The tests, which paid special attention to the cable shield, core pitch lengths and the individual strand size of the core wires, confirmed that the cables could survive more than 30 million double strokes, or 36,691km travel, in the energy chain with a test radius of 5xd.

The high-tech Chainflex CF11 data cable has an abrasion-proof and bend-resistant, halogen-free, oil- and bio-oil-resistant TPE outer jacket and an inner jacket that is also made of a TPE compound.

The cable has extremely stable braiding: two cores each stranded in pairs with short pitch lengths; core pairs also stranded with short pitch lengths — this ensures maximum EMC protection and high data transmission qualities are maintained during the working life of the cable even with bending radii reduced by 30 per cent.

Similar properties are confirmed for the CF211 series, a low-cost PVC version that is oil resistant and flame retardant with a bend-resistant tin-plated braided copper shield.

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.
