Hybrid bearing

Hybrid bearings are special rolling bearings that use a combination of materials to improve the performance and service life of the bearing. Typically, hybrid bearings consist of an inner and outer ring and rolling elements, with either ceramic or plastic elements used as rolling elements, while the rings are usually made of steel.

The use of ceramic or plastic rolling elements offers several advantages over conventional steel rolling elements:

1. Lower weight: Ceramic or plastic rolling elements are lighter than steel, which reduces the rotating masses and thus contributes to improved dynamics and efficiency of the bearing.
2. Higher speeds: Due to their lower density and better surface properties, ceramic or plastic rolling elements enable higher speeds compared to steel rolling elements.
3. Corrosion resistance: Ceramic and plastic rolling elements are less susceptible to corrosion than steel, which improves the service life of the bearing, especially in humid or corrosive environments.
4. Lower friction: Due to their smoother surface and lower density, ceramic or plastic rolling elements generate less friction and thus contribute to more efficient energy transfer.

Hybrid bearings are often used in high-performance applications, such as in aerospace, the motorsports industry, high-speed machines, and applications that place high demands on precision, speed, and reliability. By combining materials, hybrid bearings offer an optimal balance between performance, service life, and reliability, making them the preferred choice in many demanding applications.
