Understanding the Dimensions of Ball Bearing 6004

Ball bearings play a crucial role in various mechanical applications, providing the means for smooth rotational movement while reducing friction between moving parts. Among the numerous types of ball bearings available, the 6004 series is widely used across a range of industries due to its versatility and efficiency. This article delves into the dimensions and specifications of the 6004 ball bearing, offering insights into its design and usage.

What is a 6004 Ball Bearing?

The 6004 ball bearing is a single-row deep groove ball bearing that is known for its ability to accommodate both radial and axial loads in both directions. It features a simple design, making it easy to install and maintain, which is why it is commonly found in many applications, from electric motors and automotive components to industrial machines and household appliances.

Dimensions of the 6004 Ball Bearing

The dimensions of the 6004 ball bearing are standardized, ensuring compatibility with various components. The key dimensions of the 6004 ball bearing are as follows

- Inner Diameter (ID) 20 mm - Outer Diameter (OD) 42 mm - Width (W) 12 mm

These dimensions play a significant role in the bearing's performance and suitability for different applications. The inner diameter must fit the shaft, while the outer diameter should match the housing to provide optimal support and stability.

Load Capacity and Performance

One of the main advantages of the 6004 ball bearing is its high load-carrying capacity relative to its size. The design allows it to handle moderate to heavy loads while maintaining excellent rotational speeds. Its maximum radial load capacity is approximately 9,900 N, and it can handle axial loads of about 4,500 N depending on the specific application and conditions. Users must consider the operating conditions—such as speed, temperature, and lubrication—to optimize performance.

Typically constructed from high-quality steel, 6004 ball bearings are designed for durability and resistance to wear. The steel is often treated with various surface finishes to enhance corrosion resistance and extend the bearing's lifespan. Additionally, some manufacturers offer ceramic hybrid versions of the 6004, utilizing ceramic balls with steel rings for reduced weight and improved performance characteristics.

Applications

Due to its reliable performance and dimensions, the 6004 ball bearing is used in a plethora of applications. Common uses include

- Electric Motors The compact size and capability to handle high speeds make it ideal for electric motor assemblies. - Automotive Components It is often used in gearboxes, wheel hubs, and other rotating parts within vehicles. - Industrial Equipment Machinery such as conveyors and pumps frequently utilize the 6004 ball bearing for its robustness and reliability. - Consumer Goods Appliances like washing machines and fans also benefit from the stability provided by this bearing type.

Maintenance and Lubrication

Proper maintenance is essential to ensure the longevity and functionality of the 6004 ball bearing. Regular inspection for noise, vibration, or overheating can help identify potential wear. Additionally, adequate lubrication is crucial; greasing at recommended intervals based on the application's conditions helps reduce friction and prolongs the life of the bearing.

Conclusion

The 6004 ball bearing exemplifies efficiency and versatility across numerous applications, thanks to its well-defined dimensions and robust design. Understanding its specifications, load capacities, and suitable applications enables engineers and technicians to select the right bearing for their needs, optimizing performance and extending the lifespan of critical machinery. Whether in automotive, industrial, or consumer applications, the 6004 ball bearing continues to be a trusted choice for reliable movement and minimal friction.
