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 angular contact geometry are designed to carry combined radial and single-direction axial loads along a defined contact angle — typically 15° or 30° — delivering higher axial rigidity and speed capability than a four-point contact configuration under unidirectional thrust. The load is transmitted through each ball at a single contact point on both the inner and outer rings, concentrating force along the contact angle line and making them inherently stiffer and more precise under predictable, unidirectional loading conditions. This makes them the preferred choice where high-speed operation and axial preload control are critical, such as in spindle assemblies, precision actuators, and servo-driven positioning systems.
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 angular contact geometry handle?
Constant Section (CS) bearings with angular contact geometry are designed to carry combined radial and single-direction axial loads along a defined contact angle — typically 15° or 30° — delivering higher axial rigidity and speed capability than a four-point contact configuration under unidirectional thrust.
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.
