Need a stainless steel bearing for humid or corrosive conditions?
What Are Stainless Steel Deep Groove Ball Bearings?
Stainless steel deep groove ball bearings are single-row radial ball bearings designed for smooth rotation, low friction and reliable performance in environments where moisture, humidity, mild chemicals or hygiene requirements may cause standard chrome steel bearings to rust.
Compared with standard chrome steel deep groove ball bearings, stainless steel versions provide better corrosion resistance and are widely used in food processing equipment, packaging machines, pumps, medical devices, marine components, chemical machinery and outdoor automation systems. For standard chrome steel options, visit our Deep Groove Ball Bearings page.
Inner Ring
Precision-ground stainless steel raceway providing a smooth path for rolling elements.
Outer Ring
Corrosion-resistant support structure designed to fit securely into equipment housings.
Balls & Cage
Matched stainless steel rolling elements guided by a stable cage for low friction operation.
Seals / Shields
Protection against dust, moisture and contaminants, retaining internal lubrication.
Choose the Right Stainless Steel Grade for Your Application
Selecting between 440C, 304, and 316 depends on the specific balance of load capacity, running speed, and severity of the corrosive environment.
AISI 440C Stainless Steel
- Higher hardness and better wear resistance
- Suitable for higher load and higher speed applications
- Magnetic stainless steel structure
- Good corrosion resistance in humid and mildly corrosive environments
Recommended For
Electric motors, automation equipment, pumps, precision machinery, general industrial equipment.
AISI 304 Stainless Steel
- Better corrosion resistance than 440C in many humid and hygienic environments
- Non-magnetic austenitic stainless steel
- Suitable for light-load and hygiene-focused applications
- Not ideal for heavy load or high-speed conditions
Recommended For
Food machinery, packaging equipment, medical devices, clean equipment, light-duty wet environments.
AISI 316 Stainless Steel
- Excellent resistance to saltwater, chloride and aggressive chemical environments
