See igus innovations at Midlands Design and Manufacturingigus UK will be exhibiting at this year's Midlands Design and Manufacturing Show, which is colocated with Mtec 2011 and Medtec UK. Visitors to the igus stand (1641) will see new additions to the firm's maintenance-free polymer bearing ranges, which include iglidur plain bearings, igubal spherical bearings and DryLin linear bearings. In addition, examples of industry-leading E-Chain cable carriers and Chainflex continuous-flex cables will be on show.

On display at the NEC for the first time is an innovative mechanism that permits quick positional adjustment of the slide on a trapezoidal lead screw drive. Called DryLin Fast Forward (pictured), the mechanism saves a considerable amount of time when adjusting machine settings, particularly in applications that involve long lead screws. The linear slide can be positioned precisely on the trapezoidal thread using the conventional hand wheel adjustment mechanism; the Fast Forward function, on the other hand, releases the slide from the thread so it may be slid quickly to a new 'approximate' position by hand first, followed by more precise positioning with the hand wheel.

Also on display is a hybrid linear bearing that both rolls and slides. Called DryLin WJRM, this bearing system reduces driving force significantly and is particularly well-suited to applications that combine sliding and rolling movements, such as manually adjustable doors, guards, partitions and locks, as well as for light handling tasks. The range now includes carriages to suit the 16 and 20mm diameter rails.

Slewing rings and more

Matthew Aldridge of Igus states: "Visitors to our stand will be able to see first-hand that we are also the technology leader in rotational systems." The iglidur PRT slewing ring bearing systems use two self-lubricating, low-friction polymer sliding elements in place of conventional ball bearings. Suitable for OEMs looking for a ready-to-fit bearing, the units are available in a wide range of sizes, with inside diameters of 20, 30, 60, 80, 100 200 and 300mm. On display will be two new developments to the range - a toothed outer ring option, as well as a low-cost slewing ring.

An innovative compact energy chain system, the TwisterBand TB20 is able to turn eight times round its own axis. Staying close to the axis, the cost-effective system can guide energy, data and other media safely through 3000 degrees at high rotating speeds with little wear. Justin Leonard of igus UK states: "Typical applications for circular chain systems are mainly in the field of robots. They are equally well-suited in special machine design, such as radar and telescope systems, as well as medical equipment and rides at amusement parks."

Also on display for the first time in the UK is Guidelok, a horizontal guiding system developed by igus for use in the machine tool industry, particularly where unsupported travels of up to 50m are required and metal chip debris makes a gliding system difficult. Guided in a lightweight aluminium trough, the energy chain radius passes through the igus Guidelok system – a spring-loaded roller support bracket that moves away from the moving radius allowing a smooth movement. The roller bracket then springs back out behind the radius to support the upper energy chain run. Thanks to this design, no debris can settle between the sliding surfaces of the upper run and lower run of the energy chain, and the open guide trough prevents a build up of swarf or chips.

For designers and specifiers looking for cables and cabling systems, igus will be demonstrating its new Chainflex Cables Product Finder and Life Calculator, as well as the innovative QuickPin program for custom connectorised cabling.

Throughout the exhibition, experts from igus UK will be on hand to provide advice and guidance on selecting polymer bearings, energy chains and cabling assemblies for specific applications. To arrange an appointment, call Sarah Carr on +44 (0)1604 677240 or email .
