Types of Stainless Steel Bearings 

stainless steel radial ball bearing

We specialize in stainless steel radial bearings, which can support radial loads. Radial loads apply a force that is perpendicular to the direction of the shaft. Our bearings are manufactured using 440 stainless steel bearings and are constructed with machined semi-precision rings and polymer cages, allowing them to reduce friction and permit the free movement of dynamic parts under moderate loads and low speeds. 

SPB-USA offers open large size stainless steel ball bearings and shielded large size stainless steel ball bearings manufactured with these distinctive qualities.

Features and Benefits of Stainless Steel Ball Bearings

SPB-USA stainless steel bearings are highly corrosion resistant against water, chemicals, and sterilization, exhibit exceptional stability at high temperatures, and are available in a diverse range of sizes. Other features include:

  • Diverse Size Range: Sizes range from 0.6mm to 50mm Bore Diameter, with a variety of closures and lubricants to fit a wide range of applications.
  • Chemical Resistant: Stainless steel is inherently resistant to chemicals. This property protects the bearing from salinated water, gasoline, solvents, detergents, and other harsh chemicals.
  • Corrosion Resistant: Our bearings can withstand exposure to harsh elements without the risk of corrosion, eliminating the need for oil or grease as a barrier and reducing the risk of bearing failure.
  • Temperature Resistant: Stainless steel ball bearings can operate at extreme temperatures up to 574℉ with a suitable cage material or a full complement construction.
