Introduction:
This test method covers the determination of corrosionpreventive properties of greases using grease-lubricated ball bearings under dynamic wet conditions.
Woring principle:measure the grease's ability to protect the bearing from corrosion in the presence of water. The two sets of grease-coated bearings were partially immersed in water and rotated at a speed of 80 rpm during the running and stationary periods. At the end of the test, check the rust of the outer ring of the bearing.
