Testing on our test rigs

Rolling contact bearings

Bearing test rig EELPAX-200

Test rigs are available for the verification of rolling contact bearings up to an outer diameter of 320mm. Each test rig is equipped with a speed-controlled drive system. Axial, radial, or combined forces are applied with hydraulic cylinders. These features provide not only maximum test parameter accuracy but also the option of variable speeds or loads without additional effort, e.g. a defined running-in period at a reduced load.

During a test, the temperatures of the bearing outer rings, vibrations, and motor torque are continuously monitored and recorded.

Grease, splash, or circulation lubrication schemes are possible with all test rigs. The oil flow rate is adjustable, and the oil temperature is continuously controlled based on the temperatures at the housing inlets and outlets. It is also possible to perform tests with defined lubricant contamination.

In addition to running lifetime tests on our test rigs, we also offer conception, design, construction and delivery of test rigs according to your specifications.



Bearing test rig EELPAX-130

The EELPAX-130-H was developed to investigate lubrication properties. This test rig is suitable for all combinations of rotational speed, load, and temperature outlined in DIN 51819. Like all of our test rigs, hydraulic cylinders are used to apply the force which leads to a significant advantage in accuracy compared with the plate springs described in the standard. Time-dependent parameters are also possible, thus enabling different load steps without having to stop and dismantle the test rig.

The great flexibility of this test rig makes it possible to go beyond the borders of the standard and carry out sophisticated research investigations at a reasonable cost. 

Radial sealing rings

Our test rigs can also be used to test radial sealing rings with only a few modifications. Oil leakage is continuously measured while the wear width of the sealing lips and wear depth on the shaft re measured at the end of a test run. Other than the size of the seal, possible test parameters include:

  • rotational speed
  • temperature
  • lubrication and
  • eccentricity.
