Constant Section (CS) bearings manufactured from Chrome Steel maintain a uniform cross-sectional height regardless of bore diameter, making them exceptionally compact and space-efficient. Their GCr15/52100 alloy composition, hardened to HRC 60–66, provides superior load capacity and contact fatigue resistance that delivers reliable performance under high-speed, heavy-load, and demanding cyclic conditions. This combination of slim profile and mechanical strength 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 Chrome Steel balls utilize GCr15/52100 alloy spheres hardened to HRC 60–66, delivering the highest load capacity and contact fatigue resistance among standard ball materials within the same compact cross-sectional envelope. The high carbon-chromium composition provides exceptional surface hardness and elastic modulus, enabling the balls to sustain high Hertzian contact stress against the raceways under heavy radial, axial, and moment loads without premature deformation or spalling. This makes them the preferred choice in general industrial, robotic, and precision motion applications where maximum mechanical performance and cost efficiency are the primary requirements.

Why are Chrome Steel rings the most common choice for Constant Section (CS) bearings?

Constant Section (CS) bearings with Chrome Steel rings use GCr15/52100 alloy hardened to HRC 60–66, delivering the highest combination of load capacity, contact fatigue resistance, and dimensional stability among standard ring materials. This makes them the most cost-effective option for the broadest range of industrial and precision motion applications.
