drylin® linear bearings test lab & results

In the dry-tech® test lab, self-lubricating drylin® linear plain bearings, linear axes and lead screw modules are thoroughly tested. We conduct tests on our 29,600 sq. ft. facility in order to continuously develop our own products and effectively assess customer applications. Our goal is to offer the best products for every application we come across. We would be happy to test your specific application. Test results are beneficial for all customers, as they are stored in a database and incorporated into the drylin® service life calculator.

Friction and wear tests are conducted to determine the tribological properties of different material combinations. Additionally, we test for functionality, service life, durability and potential failure scenarios.

Test Lab Facts:

  • About 500 tests conducted per year
  • 29,600 sq. ft. test laboratory
  • 52 test rigs
  • Approx. 50 customer tests per year
  • 40 parallel experiments daily

Which online tools does the test data flow into?

The results from the product and material tests are used for new and further development and are incorporated into our free online tools for lifespan calculation or product discovery. Each product area has its own tools such as the expert system, which compares products based on requirements such as high compressive strength or radial forces and calculates their service life.

  • Expert system linear guides
  • Screw drive expert system
  • Drive technology configurator
  • Drive technology product finder and service life calculator
  • Predictive maintenance with smart plastics - i.Cee

Test Results

dryspin® lead screw test

Upon a customer request, the motion plastics® specialist igus compared dryspin® lead screws with two competitive products with identical high helix thread dimensions. Both in a wear test and an efficiency test, the products intended for rail technology were tested for 100,000, 200,000, 400,000 and 630,000 cycles.

drylin® SAW linear actuator test

In its in-house test laboratory, the Cologne motion plastics® specialist compared its cost-effective and completely self-lubricating drylin® SAW linear units with a competitor's product in a test of wear and functional performance. The nut of the competitor's rail broke after only 8,040 cycles. The drylin® SAW unit, in contrast, continued functioning perfectly even after more than 90,000 cycles at four times the speed.
