Understanding the Dimensions of 6800ZZ Bearings

Bearings are critical components in machinery, enabling smooth and efficient movement between different parts. One common type of bearing in use today is the 6800ZZ bearing, renowned for its unique features and dimensions that make it suitable for a wide range of applications. In this article, we will explore the dimensions of the 6800ZZ bearing, its construction, and its applications.

What is a 6800ZZ Bearing?

The 6800ZZ bearing is a type of deep groove ball bearing that comes with metal shields on both sides (hence 'ZZ'). These shields help protect the bearing from dust, dirt, and other contaminants, while also retaining lubrication, thus extending the bearing's lifespan. The '6800' designation indicates its size series, and it's characterized by a thin profile, making it ideal for applications where space is limited.

Key Dimensions

The dimensions of the 6800ZZ bearing are standardized, making it easier for manufacturers and engineers to interchange them. The key dimensions include

- Inner Diameter (ID) 10 mm - Outer Diameter (OD) 19 mm - Width (W) 5 mm

These dimensions provide a compact size that allows for versatile applications, especially in electric motors, appliances, and various industrial equipment. The 6800ZZ bearing typically has a dynamic load rating of around 4.5 kN and a static load rating of 2.3 kN, which indicates its capacity to bear loads effectively.

6800ZZ bearings are usually constructed from high-quality steel, which provides strength and durability. The races and the balls are machined to precision, allowing for low friction and smooth rotation. The ZZ designation indicates that the bearings are shielded, making them impervious to contaminants while conserving lubrication within the bearing. This design feature significantly enhances their operational longevity.

In some cases, manufacturers also produce ceramic or plastic variants of the bearing. Ceramic bearings are particularly known for their lightweight and high-speed capabilities, while plastic bearings can withstand corrosive environments, although they may not carry as high a load.

Applications

Due to their dimensions and robust construction, 6800ZZ bearings find applications across various industries. Commonly, they are employed in

1. Electric Motors Used in small motors for household appliances and tools. 2. Bicycles Frequently found in wheel hubs and bicycle cranks. 3. Printer Mechanisms Employed in 3D printers and inkjet printers for smooth operation. 4. Robotics Used in robotic arms and devices where precision and durability are paramount. 5. Automotive Found in electric windows, sunroofs, and ventilation systems in vehicles.

Conclusion

In summary, the 6800ZZ bearing is a versatile and efficient option for many applications, thanks to its dimensional specifications and robust design. Its ability to handle loads while remaining compact makes it ideal for various machinery, from household appliances to sophisticated industrial machines. Understanding the dimensions and characteristics of the 6800ZZ bearing can assist engineers and designers in selecting the right bearing for their projects, ensuring reliable performance and longevity in their applications.
