Issue 8/2014 igus®
Moving energy and lubricant-free bearings made easy
Save weight with particularly lightweight E-Chains® and plain bearings from igus®

engineers always strive to make their machines better; frequently this relates to speed and thriftiness. Weight plays an important role in this regard.

In this newsletter, learn about the highly dynamic Energy Chain® from igus® - the E4.1 light - 30% lighter than E-Chain® Series E4.1.

Find out more about our iglidur® plain bearings, which are lighter than corresponding metal solutions by a factor of 7.

The right solution to your weight problem is certain to be among them.

Enjoy reading and collecting ideas!

Four times longer service life with lightweight plastic Energy Chains®

The Kronopol operation initially fitted three wood processing machines with Energy Chains® made of steel. "These Energy Chains® only lasted six months, however," reports Grzegorz Szer, head of the electrical department at Kronopol. The heavy steel chains were finally replaced by unsupported plastic Energy Chains® from igus®. "Despite tough environmental conditions, the solution with plastic has already lasted 24 months without a single failure." Continue reading ...

Load test in the igus® lab.
21.25% lighter E-Chain® with more than 63% less sag

It is 21.25% lighter, but does that also make it less stable? igus® compared a newly developed E-Chain® in the lab with the predecessor E-Chain®. For a period of four days, both Energy Chains® were loaded with a weight of 1.6 kg in an unsupported manner. Result: at 18 mm, the new development has 63% less sag. Read the entire test report here

Customer-specific test setup: Wear comparison iglidur® H1 vs. metallic composite bearings.
Lightweight iglidur® H1 plain bearings - more than four times less wear than metallic composite bearings

A customer asked the igus® lab to compare the wear between metal composite bearings and iglidur® H1 plain bearings. A purpose-built test setup emulated the customer application - the door hinge on an ambulance. After about 500,000 cycles, the iglidur® plain bearings exhibited more than four times less wear. Read the entire test report here


Where is igus® hiding? e-chain®
Every gram counts.
Lightweight E-Chain® in a helicopter
Aerospace engineers are primarily concerned with the weight of installed components. This vector® submission reduced the weight of a Series 2828 igus® E-Chain® by 628 grams by replacing the separators. Instead of the previously used 16 separators, the chain now only uses 8. The substitution had no negative impact on any other E-Chain® properties. Read more here
