ceramic bearings 6802

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

Ceramic bearings, particularly the 6802 model, represent a significant advancement in bearing technology due to their unique properties and widespread applications. Below is a detailed introduction to ceramic bearings 6802 in English:

Overview

Ceramic bearings 6802 are a type of bearing that utilizes ceramic materials, such as silicon carbide (SiC), in their construction. These bearings are designed to offer superior performance in terms of durability, high-temperature resistance, and corrosion resistance compared to traditional metal bearings.

Key Features

1. Material Composition:

• Ceramic Balls: Made of silicon carbide (SiC), which is known for its high hardness, wear resistance, and corrosion resistance.

• Raceways and Rings: Typically made of high-quality steel or other suitable materials to complement the ceramic balls.

• Retainers: Often constructed from materials like PETFE, which ensure smooth movement and longevity.

2. Dimensional Specifications:

• Inner Diameter: 15mm

• Outer Diameter: 24mm

• Width/Thickness: 5mm

3. Design:

• Open structure allows for easy lubrication and maintenance.

• Available in various designs, including deep groove ball bearings, which are suitable for high-speed and high-load applications.

Applications

Ceramic bearings 6802 are widely used in various industries and applications due to their exceptional properties:

1. Medical Equipment: Where high precision, low friction, and corrosion resistance are crucial, such as in surgical instruments and medical imaging machines.

2. Optical Instruments: Where precise and stable movements are required, such as in telescopes, microscopes, and other precision measurement devices.

3. High-Speed Machinery: Including high-speed spindles, routers, and milling machines, where high-speed rotation and reduced heat generation are essential.

4. High-Speed Motors: Electric motors operating at high speeds benefit from the reduced friction and wear of ceramic bearings.

5. Food Processing Machinery: Ceramic bearings offer corrosion resistance and hygiene benefits, making them ideal for food processing environments.

Advantages

1. High-Speed Rotation: Ceramic bearings can operate at higher speeds with reduced friction and wear, enhancing machine performance.

2. Heat Resistance: Ceramic materials have a higher melting point and better thermal stability, allowing them to operate in high-temperature environments.

3. Corrosion Resistance: Ceramic bearings are resistant to many chemicals and corrosive environments, extending their lifespan and reducing maintenance costs.

4. Lightweight: Ceramic materials are lighter than traditional metals, reducing the overall weight of the machinery and improving energy efficiency.

Conclusion

Ceramic bearings 6802 are a high-performance bearing solution that offers numerous advantages over traditional metal bearings. Their unique properties make them ideal for a wide range of applications in various industries, from medical equipment to high-speed machinery. With their superior durability, heat resistance, and corrosion resistance, ceramic bearings 6802 are poised to continue playing a crucial role in advancing machinery and equipment performance.
