Consistent Cross-Section Across Sizes
The defining characteristics of constant section (CS) bearings is their fixed radial cross-section (the dimension between the bore and the outer diameter, and the width), which remains almost constant within a variety of bore diameter ranges in a specific series.
Unlike standard bearings where the cross-section increases with bore size, this “constant bearing” characteristic ensures predictable dimensions regardless of the shaft size chosen from that series, simplifying multi-shaft system designs.
Optimized Space Utilization
The constant section (CS) bearings design excels in applications in the limited space (particularly radial space), but varying shaft sizes might be needed.
Because the cross-section doesn’t grow significantly with the bore, designers can accommodate larger shafts without increasing the housing diameter or overall machine envelope.
If you need to upgrading shaft capacity within an existing design footprint, or standardizing housing components across different models, the constant section (CS) bearing will be your ideal choice.
Simplified Design and Inventory
In constant section (CS) bearings, the “constant” of the cross-section simplifies the design process. Engineers can often utilize similar or identical housing bore dimensions for multiple shaft sizes within the same CS bearing series.
This standardisation can lead to reduced design complexity, easier manufacturing setups, and potentially lower inventory costs, because a series of products may only require a relatively small number of relevant unique components (such as casings or seals).

FREQUENTLY ASKED QUESTIONS
What's the main difference between Constant Section and standard bearings?
The key difference is how the cross-section behaves as the bore size changes within a series.
Constant section (CS) bearings maintain a nearly identical cross-section, while standard bearings have a cross-section that increases with the bore diameter.
Are Constant Section bearings always "thin"?
While many Constant Section (CS) Bearings are also thin section bearings (small cross-section relative to bore), the term "constant section" specifically emphasizes the consistency of that cross-section across different sizes, not just its absolute thinness.
What applications benefit most from Constant Section bearings?
Applications requiring compact design across multiple, similar machines with varying shaft sizes, or where standardizing housing components is advantageous. Examples include robotics, semiconductor equipment, and medical devices.
