ZAN

ZAN - test rig for testing journal bearings

Rig ZAN is used for investigation of statically loaded journal-sliding bearing. The stand is especially suitable for testing bearings that are lubricated with contaminated lubricants. Rotational speed and loading are programmable within the wide range.
