Stainless Steel Rollers
Stainless Steel Rollers
Corrosion-Resistant Rollers for Precision, Cleanroom & Harsh Environments
Stainless steel rollers are engineered for environments where strength must meet resistance to corrosion, moisture, and chemical exposure. Manufactured from high-performance stainless alloys including AISI 302, AISI 316, and AISI 420, these rollers are ideal for industries like food processing, medical equipment, marine systems, and cleanroom automation.
At Atlas Ball & Bearing, we supply stainless steel rollers that combine structural integrity with lasting surface stability, ensuring reliable performance in the most demanding applications.
Stainless Steel Rollers
Available Grades and Hardness
We manufacture stainless steel rollers in the following grades:
AISI 302 – Austenitic stainless steel offering excellent corrosion resistance and moderate strength. Suitable for low-magnetic applications and cleanroom use.
AISI 316 – Marine-grade stainless steel with superior resistance to chlorides and harsh chemicals. Ideal for food, pharmaceutical, and offshore environments.
AISI 420 – Martensitic stainless steel delivering high hardness and wear resistance. Commonly used in bearing assemblies and applications where durability is key.
Standard Hardness Range:
AISI 420 rollers: Heat treated to 58–65 HRC (653–832 Hv10)
AISI 302/316: Supplied in annealed or cold-worked condition depending on application
These materials are selected to ensure:
Resistance to corrosion and chemical exposure
Clean, low-maintenance performance
Long service life, even in aggressive or sterile settings
