• Corrosion Tester

Corrosion Tester

Measures the ability of a grease to protect a bearing against corrosion in the presence of water. Two sets of grease-coated bearings per station are partially immersed in water and rotated at a speed of 80 rpm in a sequence of running and resting periods. At the end of the test, the raceways of the bearing outer rings are inspected for rust. 

  • Conforms to ASTM D6138, ISO 11007, DIN 51802 and related specifications
  • Touch screen panel allows easy-to-set-up sequences to define your customized test setup or run the standard test
  • Extension unit allows additions of 2 test bearings to the basic station, up to a maximum of 8 positions

The Corrosion Tester K9445X has been developed for testing lubricating greases on their corrosion inhabiting characteristics in rolling bearings in the presence of either distilled or demineralized water, or salt water or synthetic sea water and under no applied load. It can also be used to test the corrosion inhibiting characteristics of lubricating oils. 

Water contamination can occur in cases where bearing housings are mounted outdoors, in machines regularly subject to water or steam - papermaking machines, food-processing machines - or in underwater applications. Lubricating greases consist of various components which chemically may look alike. Small changes or differences in composition, different suppliers or changes in the process of making greases may result in large performance differences of corrosion inhibition.
