AISI 440C: High hardness (HRC 58+), magnetic, high load capacity.
AISI 304: Maximum corrosion resistance, non-magnetic, low load.
High-performance corrosion-resistant deep groove ball bearings. Manufactured from premium AISI 440C (hardened) or AISI 304 (non-magnetic) stainless steel. Engineered for hygiene-critical and corrosive environments such as food processing, medical devices, and marine equipment.
AISI 440C: High hardness (HRC 58+), magnetic, high load capacity.
AISI 304: Maximum corrosion resistance, non-magnetic, low load.
Resistant to wash-downs, cleaning agents, and sterilization.
Available with NSF H1 certified grease.
Open, ZZ (Shields), or 2RS (Rubber Seals) options.
To Share:
Standard chrome steel bearings often fail prematurely when exposed to moisture, chemicals, or frequent wash-downs due to rust. Our Stainless Steel Deep Groove Ball Bearingsprovide the ultimate solution for these challenging environments.
We offer two distinct grades to match your specific needs:
This is the standard for stainless bearings. These bearings are heat-treated to achieve high hardness, allowing them to carry loads similar to standard chrome steel bearings while offering good corrosion resistance. They are magnetic and ideal for high-speed, high-load applications in damp environments.

For applications requiring extreme corrosion resistance (e.g., seawater, acids) or non-magnetic properties (e.g., MRI scanners), we offer bearings made from AISI 304. While softer and suitable for lower loads, they provide superior rust protection.

All bearings can be customized with food-grade grease and special seals to ensure compliance with hygiene standards in food and pharmaceutical industries.
