Thin Section Bearings
As a trusted thin section bearing distributor, Alpine Bearing proudly offers multiple configurations and materials to meet demanding engineering specifications in your industry.
Types of Available Thin Section Bearings
Alpine Bearing offers a complete selection of thin section bearings that support different load directions and system requirements. These include angular contact, four-point contact, and radial configurations, each available in open and/or sealed styles depending on your application needs.
Angular Contact Ball Bearings
Angular contact bearings provide greater thrust capacity than a radial contact or four-point contact bearing. Their counterbored outer race gives angular contact bearings unidirectional thrust capacity are ideal when higher axial loads are present. To establish and maintain the contact angle, angular bearings are typically mounted in pairs to support reversing thrust forces.Four-Point Contact Ball Bearings
Standard bearing lines handle either radial or axial loads. The gothic arch geometry of the inner and outer races of the Kaydon Reali-Slim® four-point contact bearing line enables a single bearing to carry three types of loading (radial, axial, and moment) simultaneously.
This makes it the bearing of choice for many applications since a single four-point contact bearing can often replace two separate bearings in a simplified way providing a simplified design. The unique contact pattern allows for stable operation under complex loading conditions, especially in systems with variable directional forces.
Radial Contact Ball Bearings
The radial contact bearing is a single-row radial ball-bearing of conventional design with a Conrad-type assembly. They are optimized for radial loads and can handle axial forces when mounted in specific configurations. The simple, compact design makes these thin section bearings well-suited for high-speed rotation in space-limited assemblies..Performance Advantages of Thin Section Bearings
Thin-section bearings work to reduce weight and conserve space without sacrificing rotational stability or load capacity. Their streamlined geometry allows for consistent torque and smooth motion, even in applications with minimal clearance or tight mechanical constraints
By minimizing cross-sectional size while maintaining strength, thin section bearings contribute to more efficient designs and lower overall system inertia. These advantages make them a practical solution for precision assemblies that demand both performance and a compact footprint.
Applications in High-Precision Systems
Thin section bearings are frequently integrated into systems where tight tolerances and low friction are critical. Alpine Bearing supplies these components to OEMs across industries that rely on these reliable, space-saving solutions. These applications include the following and more:- Gimbal and Pointing Systems: enabling precise angular control in aerospace and defense applications
