Bearing_Noise_Tester_at_AST_BearingsBearing material plays an integral role in operating performance and life, so choosing a material with desirable properties is an important design decision.

AST’s complimentary white paper section of our website features an educational article examining some of these considerations to assist you in making the best choice for bearings in your unique application. The white paper can be read by clicking here.

The in-depth look at bearing materials provides insights into factors such as temperature, strength, wear resistance, corrosion, noise, chemical composition, fatigue life, lubrication and more. It focuses on the following categories:

  • Bearings Made of Chrome Steel – SAE 52100
    • Extra clean 52100 chrome steel
  • Bearings Made of Stainless Steels
    • Martensitic Stainless Steel – AISI 440C
    • Martensitic Stainless Steel – ACD34 / KS440 / X65Cr13
    • Martensitic Stainless Steel – SV30
  • AISI316 Austenitic Stainless Steel
  • Other 300 Series Stainless Steel
  • Bearings Made of Carbon Alloy Steel
    • Medium Carbon Alloy Steel
    • Low Carbon Alloy Steel
  • Bearings Made of Plastics and Non-Metallic Materials
    • Cages
    • Seals
  • Bearings Made of Ceramic Materials
