NSK 6804ZZCM Bearing Parameter Introduction:
The NSK 6804ZZCM is a deep groove ball bearing. Here are its parameter details:
1. Model: NSK 6804ZZCM
- "6804" represents the bearing model, typically denoted by numbers.
- "ZZ" indicates double metal shields, used to protect the bearing internals from dust and contaminants.
- "CM" signifies internal clearance adjustment for optimized bearing performance.
2. Bearing Type: Deep Groove Ball Bearing
- Deep groove ball bearings are a common type of bearing known for their good radial load-carrying capacity and moderate axial load-carrying capacity.
- They are suitable for various applications, including power tools, household appliances, automotive components, etc.
3. Dimensional Parameters:
- Inner Diameter: The inner diameter of the 6804 bearing is a standard size, measuring 20 millimeters.
- Outer Diameter: The outer diameter of the 6804 bearing is a standard size, measuring 32 millimeters.
- Width: The width of the 6804 bearing is a standard size, measuring 7 millimeters.
4. Clearance: The CM type bearing has internal clearance adjustment to ensure proper clearance during normal operation. Clearance refers to the gap between the internal components of the bearing, which is crucial for bearing operation and load-carrying capacity.
5. Sealing Method: The 6804ZZCM bearing employs double metal shields (ZZ) as a sealing method. This sealing mechanism prevents dust, contaminants, and other particles from entering the bearing internals, enhancing the bearing's lifespan and performance.
