Constant Section (CS) bearings manufactured from Stainless Steel maintain a uniform cross-sectional height regardless of bore diameter, making them exceptionally compact and space-efficient. Their AISI 440C alloy composition, hardened to HRC 58–62, provides inherent corrosion resistance that eliminates the need for surface coatings, sustaining reliable performance in humid, washdown, or chemically aggressive environments. This combination of slim profile and environmental durability makes them a go-to choice in robotics, medical, and semiconductor applications.

Constant Section (CS) bearings with four-point contact geometry are uniquely capable of carrying radial loads, axial loads in both directions, and moment loads simultaneously within a single row — a combined load capacity that neither a standard radial bearing nor a single-row angular contact bearing can match alone. The four-point contact is achieved through a gothic arch raceway profile, where each ball contacts both the inner and outer rings at two distinct points, effectively replicating the function of a back-to-back angular contact pair in a fraction of the axial space. This makes them the preferred choice where multi-directional loading and spatial compactness must be achieved together, such as in robotic joints, rotary tables, and slewing applications.

Constant Section (CS) bearings with Stainless Steel balls utilize AISI 440C alloy spheres hardened to HRC 58–62, providing inherent corrosion resistance that eliminates the need for surface coatings while maintaining adequate load capacity and contact fatigue life within the same compact cross-sectional envelope. The high chromium composition forms a stable passive oxide layer on the ball surface, enabling reliable performance in humid, washdown, and chemically aggressive environments where Chrome Steel balls would require additional protection. This makes them the preferred choice in food processing, medical, and marine applications where environmental exposure and hygiene requirements take precedence over maximum load capacity.

Why are Stainless Steel rings a preferred choice for Constant Section (CS) bearings in demanding environments?

Constant Section (CS) bearings with Stainless Steel rings use AISI 440C alloy hardened to HRC 58–62, delivering inherent corrosion resistance and sustained performance in humid, washdown, and chemically aggressive conditions without the need for additional surface protection. This makes them the most reliable option for applications where environmental exposure and hygiene requirements are the primary design constraints.

What load directions can Constant Section (CS) bearings with four-point contact geometry handle?

Constant Section (CS) bearings with four-point contact geometry are uniquely capable of carrying radial loads, axial loads in both directions, and moment loads simultaneously within a single row — a combined load capacity that neither a standard radial bearing nor a single-row angular contact bearing can match alone.

Why are Stainless Steel balls the most common choice for Constant Section (CS) bearings in demanding environments?

Constant Section (CS) bearings with Stainless Steel balls utilize AISI 440C alloy spheres hardened to HRC 58–62, delivering inherent corrosion resistance and adequate load capacity without the need for additional surface protection. This makes them the most dependable option for applications where environmental exposure and hygiene requirements are the primary design constraints.
