Understanding the Specifications of the 6204 ZZ Bearing
The 6204 ZZ bearing is a widely used deep groove ball bearing celebrated for its versatility, durability, and ability to perform reliably in various applications. Understanding its specifications is essential for selecting the right bearing for your needs, so let's delve into the details.
What is a 6204 ZZ Bearing?
The designation '6204' refers to the bearing's size and design, specifically a deep groove ball bearing. The 'ZZ' suffix indicates that the bearing comes with metal shields on both sides, which provide robust protection from contaminants while retaining lubrication. This feature is particularly valuable in environments where exposure to dirt and moisture is a concern.
Key Specifications
1. Inner Diameter (ID) The inner diameter of the 6204 bearing is 20 mm. This measurement is critical for ensuring that the bearing fits snugly onto the shaft it is intended to support.
2. Outer Diameter (OD) The outer diameter is 47 mm. This is the total width of the bearing and is crucial for ensuring it fits properly within its housing.
3. Width The width of the 6204 bearing is 14 mm. This compact size allows for installation in tight spaces while supporting significant loads.
4. Load Ratings - Dynamic Load Rating (C) Approximately 10,000 N. This rating indicates the maximum load the bearing can withstand under dynamic conditions. - Static Load Rating (C0) Approximately 5,600 N. This rating refers to the maximum load that the bearing can support when stationary.
5. Speed Rating The 6204 bearing typically has a maximum operational speed of around 16,000 RPM in optimal conditions. However, factors such as temperature, lubrication, and load can influence this maximum speed, and it's advisable to consult manufacturer specifications for precise figures.
6. Material The 6204 ZZ bearing is generally made of high-carbon chromium steel, which contributes to its strength and wear resistance. Some manufacturers may offer alternative materials for specific applications, including stainless steel options for corrosive environments.
7. Lubrication This bearing is usually pre-lubricated with grease, eliminating the need for additional lubrication during initial use. However, regular maintenance checks are still recommended to ensure optimal performance.
Applications
The versatility of the 6204 ZZ bearing makes it suitable for a wide range of applications. It is commonly found in electric motors, automotive components, household appliances, and industrial machinery. Its ability to operate effectively under various conditions ensures that it meets the demands of diverse operational environments.
