The rings are manufactured from high-grade forged steel, chosen for its consistent mechanical properties and ability to withstand thermal processing. Raceway surfaces are through-hardened to achieve a hardness range of 55 to 62 HRC, providing excellent resistance to rolling contact fatigue, surface indentation, and abrasive wear. This treatment ensures that the raceways maintain their geometric integrity throughout the bearing's operational life.

The 020 Series is equipped with NBR lip seals positioned on both the upper and lower faces. These seals serve a dual purpose: retaining the lubricant within the bearing cavity and excluding external contaminants such as dust, water, and fine particulate matter. The seal design maintains consistent contact pressure during rotation, ensuring reliable protection in diverse operating environments ranging from clean industrial settings to harsh outdoor conditions.
