This Series rings are manufactured from high-quality forged steel, selected for its mechanical consistency and response to thermal processing. The raceways undergo a controlled through-hardening treatment, achieving a surface hardness range of 55 to 62 HRC. This hardness provides effective resistance to rolling contact fatigue, surface indentation, and abrasive wear while preserving the core toughness needed to absorb operational shocks

Effective sealing is essential for maintaining long-term reliability in real-world operating conditions. This series incorporates NBR lip seals on both the upper and lower faces, creating a dual barrier against external contaminants. These seals effectively block the ingress of dust, moisture, and particulate matter while retaining the lubricant within the bearing cavity. The seal design accommodates relative rotational movement without compromising contact integrity.
