Ball Bearing Steel: 440C Vs. 52100 In A Corrosive
Nov 01, 2010· The test atmosphere was moist carbon dioxide at a pressure of about 3 MPa, and bearings were deliberately contaminated with a representative amount of sodium chloride. The objective of the tests was to compare the rolling-contact fatigue performance of the materials and to look for other failure mechanisms in the ball bearings.
Bearing Maintenance Practices to Ensure Maximum Bearing …
contact pressure increases at the edge of the dent. Higher stresses result in shorter fatigue life. The second mechanism is wear. While balls do roll in a ball bearing, due to the curvature of the balls and races, there is some sliding that occurs as well. The sliding portions of the contact, when contamination
