Stainless Steel Ball Bearings

Stainless steel bearings are a popular material choice for many extreme environments due to their characteristics of stainless steel that deliver higher corrosion resistance and superior hardness. Here at IBSCO we offer an extensive inventory of stainless steel bearings in inch and metric sizes.

Stainless Steel Bearings

Stainless Steel bearings offer distinct advantages in robust applications with the capability to handle extreme high loads and fast RPMs. Further advantages include preciseness because of the clearance that stainless steel bearings can reach.

The performance benefits of stainless steel make these bearings ideal for extreme environments and applications like food & beverage, medical and aerospace applications. In these environments, moisture, corrosive or abrasive materials are present. Based on the toughness of stainless steel, bearings made of this material are likely to have an extended service life, reduce maintenance and equipment downtime.

Specifiers of IBSCO stainless steel ball bearings have a choice of two stainless steel options, both providing excellent hardness characteristics and a high level of corrosion resistance. We offer stainless steel bearings in metric and inch sizes, flanged or unflanged and by open and shielded bearings.

Additional Benefits of Stainless Bearings

  • High Efficiency
  • Low Torque
  • Long Bearing Life
  • Low Noise Levels
  • Superior Hardness
  • Anti-Corrosive
  • Heat Resistant


Our stainless steel ball bearings are ideal for a diverse range of different industries:

Specific applications that we have built for customers include vacuums, tools, motors and fans.

DD400™ Steel Bearings

0.7% C; 13% Cr
A 400 series Martensitic stainless steel combined with a proprietary heat treating process, miniature and instrument bearings manufactured from "DD" equal or surpass AISI bearings in hardness and corrosion resistance, and offer superior low noise characteristics. DD400 stainless steel bearings commonly run smoother, last longer, and provide better performance at low torque.

AISI 440C Steel Bearings

1% C, 17% Cr, .5% Mo
A hardened , martensitic stainless steel, 440C is the standard choice for a wide range of military and commercial applications. 440C stainless steel bearings suitable for applications which require corrosion resistance in a thermal range from room to mid-hot.
