Constant Section (CS) Bearings

Constant Section (CS) Bearings are ideal for applications with strict space constraints, featuring a square cross-section that remains consistent throughout the series. This design enables high performance in compact environments, making them especially suited for demanding industrial uses.

What Are Constant Section (CS) Bearings?

Constant Section Bearings, commonly abbreviated as CS Bearings, are specially engineered thin section bearings that maintain a consistent cross-sectional geometry across different bore sizes. Unlike conventional bearings, where the cross-section varies with size, CS Bearings preserve their small, typically square cross-section—making them ideal for compact mechanical assemblies.

Key Characteristics

Space-Saving Design: Engineered for environments where minimal radial space is available.
Consistent Cross-Section: Within each series, the cross-sectional profile remains constant, which simplifies design integration.
Versatile Load Handling: Certain configurations allow the bearing to support both axial and radial loads effectively.

Available Bearing Types

There are three primary CS Bearing types:

Deep Groove Radial Contact Bearings: Designed primarily for radial loads and moderate axial loads.
Four-Point Contact Bearings: These are the most widely used CS bearings, capable of supporting axial loads in both directions along with radial loads. Their performance is comparable to that of double row angular contact bearings.
Angular Contact Bearings: Suitable for high-speed applications with combined load demands, but typically not used in CS designs due to space efficiency limitations.

Why Choose Four-Point Contact CS Bearings?

We focus on offering four-point contact CS Bearings because of their superior versatility. Thanks to their gothic arch raceway design, they allow for four points of contact between balls and raceways, which enhances their ability to carry combined loads efficiently.

Interchangeability

Our CS Bearings are fully interchangeable with KAYDON equivalents, offering the same dimensional standards and performance characteristics. This ensures seamless integration into existing systems without the need for design alterations.

Applications

Constant Section Bearings are commonly used in:

Robotics and automation equipment
Aerospace navigation and control systems
Medical imaging devices
Precision machinery where installation space is extremely limited

Conclusion

Whether you’re working with aerospace systems, robotic arms, or high-precision instruments, Constant Section Bearings offer a compact, high-performance solution that meets the most demanding engineering requirements. Contact us to find the best four-point contact CS bearing for your project.
