Stainless Steel Deep Groove Ball Bearings

Stainless steel deep groove ball bearings is a common type of bearings. AISI SUS440 and SUS304 are two common materials for stainless steel deep groove ball bearings. Designed to handle a combination of radial and axial forces at a range of speeds, temperatures, and environments for an extended period with minimal friction.

Bearings Datas

Stainless steel ball bearings can resist corrosion caused by moisture and other individual medium. AISI SUS440 and SUS304 are two common materials for stainless steel deep groove ball bearings. The stainless deep groove ball bearings and standard deep groove ball bearings made of chrome steel have the same deep groove raceway. The fit between raceway and balls is very well. Even under the condition of high speed, stainless steel deep groove ball bearings not only bear radial load, but also can withstand two-way axial load.

Difference Between SUS440 and SUS304

SUS440 hardness can reach 58 after vacuum quenching decarburization treatment, suitable for use in weak acid-base and high-load environments. Because of its high carbon content and magnetism, its corrosion resistance is not as good as SUS304. To sum up, bearings of SUS440 can reach 1500RPM, hardness is 52-58HRC.

SUS304 material contains large nickel content and low carbon content, therefore SUS 304 material is soft and has a hardness of about 25. SUS304 material bearings are not suitable for high-load rotation and are suitable for use in strong acid and alkali environments. To sum up, bearings of SUS304 is soft and non-magnetic, with Strong acid and alkali resistance and low revolving seed and low precision.

Applications of Stainless Steel Bearings

Designed to handle a combination of radial and axial forces at a range of speeds, temperatures, and environments for an extended period with minimal friction. Stainless steel bearings can be used on below common applications:

  • Medical equipment,
  • Low temperature engineering,
  • Optical Instruments,
  • High-speed machine tools,
  • High-speed motor,
  • Printing machinery,
  • Food processing machinery,
  • Others.
