Endurance testing on high-performance polymers
56 iglidur® plain bearings prove their mettle on a tour around the world

We have started a particularly special test for the 30th birthday of our iglidur® polymer plain bearings and for the 50th birthday of igus®: a compact car, equipped with iglidur® bearing technology, is traveling around the world. On their way to igus® customers in all corners of the world, the bearings need to stand up to rough roads, dust, mud, heat, and cold.

Plain bearings from igus® were installed in 56 locations on the car, for the most part as replacements for metallic bearings: for instance in the choke valve, the gear switch, the window mechanism, the roof system, the pedal mechanism, the alternator ... Find out more in the iglidur® on tour brochure (download PDF brochure here).

After the tour start in India, the car will travel to China, Japan, South Korea, Taiwan, Brazil, and the United States. The tour schedule will then end up in Europe, where the car will also visit customers, trade fairs, and igus® branch offices.

Does "plastics for longer life®" - reducing costs and improving technology - actually work? Follow the long trip around the world in the "iglidur® on tour" blog or on our facebook page. Reports, videos, and photos in these provide exciting insights into the trip and the worldwide uses of products made from high-performance polymers.

Space-saving installation with Triflex® R
triflex® R
The universal assembly kit facilitates on-site adjustment of the energy supply system. This simplifies project planning.
Today, robots are an essential component of turnkey assembly plants in the automotive industry. As a rule, they need to function and perform very hard labour. Multi-dimensional motion control energy supply systems ensure maximum flexibility and the longest service lives on all complex motions. The so-called trailer principle (ball and socket connection similar to the trailer coupling in automobiles) gives the Triflex® R high tensile strength absorption, which means flexible movements in all axis with a tested tensile strength of up to 2,340 N.

Product of the month
Keep spool - guide various media in various directions at the same time e-spool

Guide a variety of cables in confined space. e-spool is a unique combination of two different energy supply systems: a standard e-chain is guided by a roller and uses an integrated retaining spring to ensure that the energy supply system always has exactly the correct length and tension. In the home position, the E-Chain® is completely rolled up to save space.

  • No tensile forces on cables
  • One drum can accommodate a variety of media diameters
  • Energy can be guided in any direction (horizontally, vertically, diagonally... everything can be done with one chain)
  • Space-saving, no 'cable junction'
  • No lower run is left behind, paths stay free
  • Cable diameters up to 17 mm

Insights from the igus® lab
Service life test: thermal compensation cable lasts more than 97 million strokes
Chainflex® lab
Chainflex® lasts: No impairment after 97 million stroke.
Always in motion, while working reliably - the CFTHERMO.K001 thermal compensation cable lasted more than 97 million strokes in our test lab in an E-Chain®. The long-term test was conducted with the following test parameters:
  • Cable length: 3 metres
  • Acceleration: 0.5 m/s²
  • Speed: 1 m/s
  • Ambient temperature: 25°C
  • Chain type: 1500.125.048.0
  • Bending radius: 48 mm

Result: a visual inspection and a measurement of the Ohm resistance was performed after 97 million strokes. All parameters of the intact cable were OK.

Insights from the igus® lab
Wear test for customer: iglidur® J350 versus PPA GF-30 shaft
The iglidur® J350 bearings exhibited only minimal wear after 845,200 cycles.
The iglidur® J350 material was tested for a customer from the automobile industry. In addition to the required temperature and media-resistance, the primary reasons were good wear-resistance against the PPA GF-30 plastic shaft used by the customer. The igus® test lab conducted a wear test using the customer's original shaft material under the following conditions to explicitly test the good suitability of iglidur® J350:
  • Load: 16 N
  • Pivot angle: 20°
  • Speed: 2 Hz ≙ 0.007 m/s
  • Temperature: 50% of the time: 150°C; 30% of the time: 120°C; 20% of the time: room temperature
  • Running time: > 800,000 cycles ≙ approx. 3 km

Result: The iglidur® J350 bearings only exhibited minimal wear of 3.4 µm/km. No wear was measured on the PPA GF30 shaft.
