igus launches new sizes and diameters for iglidur round bars and plates

Plastic and plain bearing specialist igus enhances its special program for tribo polymer applications with iglidur semi-finished products in new sizes and diameters.

Body: Round bars are available in lengths from 100 to 1000 mm and in diameters from 10 to 100 mm; iglidur plates in thickness of 2 to 25 mm lie in store at igus. With these additional widths, designers gain more scope for individual design. Upon request, igus offers the manufacturing of special parts according to the drawing.

iglidur round bars and plates from the tribo polymer specialist igus are becoming more and more diverse and facilitates users adaptations of individual machine requirements. Mechanically machined bearings made of lubrication-free igus high-performance plastics are used wherever standard moulded parts are not worth the effort. Therefore the bearings are also appropriated for special parts as well as for smallest and medium series. With the scale of materials and sizes it is possible, to quickly make prototypes and to test the applicability for the series in a cost-effective way.

Large range of materials and sizes
Because igus tribo semi-finished products as well as the bearings are made of the tested iglidur plain bearing materials, all respective bearings can be calculated in advance online with the help of the specially developed expert system. Meanwhile 10 iglidur materials with specific features are available for a large variety of branches, such as the food, tobacco or automobile industry. Round materials, for example in the blue iglidur A350 material were available in diameters of 30, 40, 50 and 60 mm. Now they are also available in the small 20 mm diameter. They are suitable for medium to high loads and temperatures up to +180 °C. In addition they conform with FDA requirements and the first choice for the food industry. Round bars made of the material J 4 are now available in four new dimensions: in length of 20, 40, 50 and 60 mm.
igus round materials are available from stock in full bars up to 1 m in increments of 100 mm. Diameters vary between 10 and 100 mm.

iglidur J plates in seven thickness
The scope also grows for slide rails and rings: iglidur plates that are suitable for the production of such parts are currently available in seven material thicknesses from 2 to 25 mm. When used for guide tubes in operation tables, telescope arms for loading cranes or slide rails, all plates from igus are made of the proven tribo-optimised plastic iglidur J. The high-performance material eliminates low friction values in dry runs, it is exceedingly wear-resistant, lubrication and maintenance-free as well as resistant to chemicals.

Finished forms with igus speedicut
iglidur semi-finished products can be directly manufactured at igus – customized for your own processing. Furthermore, igus offers a special service with “speedicut”: With it you can directly get semi-finished product tools according to your own drawings. After a very short quotation process, the first prototypes or smallest series are deliverable within 10 days according to the customer’s requirements.

igus RX tube proves itself in a test with real conditions

The plastic energy tube RX, from igus, successfully resists chips when put through hard operation. This test result concludes after a defined period of 100,000 double strokes and a steady feed of metal chips with different sizes. Comparisons highlight that statements about chip tightness of energy tubes can only be made on the basis of test that simulate real operating conditions.

If moving cables in the workspace of lathes, milling and sawing machines need to be protected, energy chains need to be chip tight inwardly and simultaneously guide the cables with low abrasion. For this purpose, igus has already developed its first foldable plastic energy tube R68. The latest energy tube RX now offers comprehensive protection against chips of any size.

A test is not equal to any other test
In order to be able to make statements about the tightness of energy tubes, the tubes need to be extensively tested. Here the IP classifications serve as an indicator. For over 10 years now igus continues to check energy tubes in the company-owned test laboratory in Cologne. There are several advantages of the igus test series: One being that the test cycles take place among real environmental conditions. To make statements about the real tightness of an energy tube, its subsequent use needs to be simulated precisely.

Simulation close to reality: 100,000 double strokes among impacts of chips
For this reason, igus has developed a standardized test to move energy tubes over 100,000 double strokes. At the same time, a defined load of chips of different sizes is periodically poured on the energy tube again and again. The principle is comparable to a washing machine drum. At the end of the cycles it is analysed how many grams of chips can get into interior space. The result was that only 0.23 grams of chips were in RX tube after 100,000 double strokes with a feed of 1,000 grams of metal chips. This is equal to 0.023 percent.

The rounded outside profile lets chips fall off
Comparative tests with other manufacturers’ energy chains show a much higher volume of chips in the inside of the tube. The reason for the better result of the RX tube is its rounded profile. On its smooth and convex outer contour the chips simply fall out of on contact with the surface. Apart from that, igus verifies that the chips are deposited in the stop system of the energy tube. This could lead to a change of the bending radius resulting in the tube not moveing safe and crashing against projecting edges at the worst. The RX tube offers best protection due to especially smooth contours and tight production tolerances – no chips got between the stoppers during the test. The results from igus show that tests among real conditions need to be performed to get reliable statements about the chip tightness of an energy tube in operation.
