6804zz Bearing Product Overview & Core Advantages
The 6804zz is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Engineered with shielded construction on both sides, it offers effective protection against contaminant ingress while retaining lubrication. Manufactured to ABEC-1 precision class standards, this bearing provides a robust solution for applications requiring high-speed operation (up to 25,000 rpm) and consistent performance under radial loads. Its compact design, with a 20 mm bore and 32 mm outside diameter, makes it an ideal choice for space-constrained assemblies demanding precision and durability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6804 | Basic bearing designation indicating a deep groove ball bearing with 20mm bore, 32mm OD, and 7mm width. |
| zz | Denotes shielded construction on both sides, providing non-contact protection against dust and debris while maintaining low torque characteristics. |
6804zz Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and single row design enable efficient handling of radial loads (dynamic: 904 lbf, static: 554 lbf), making it suitable for various mechanical power transmission systems.
- High-Speed Capability: With a limiting speed of 25,000 rpm and a stainless steel cage, the bearing maintains stability and reduced friction at high rotational velocities.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with controlled radial internal clearance (C0: 0.006mm to 0.020mm) ensures consistent performance and smooth operation.
- Durable Construction: Both rings and balls are made from chrome steel for excellent wear resistance and fatigue life, while the stainless steel cage provides corrosion resistance.
- Shielded Protection: The zz shields help retain lubricant and exclude contaminants, extending service intervals in demanding environments.
6804zz Bearing Typical Application Areas
- Electric Motors and small precision motors requiring high-speed operation
- Power Tools and handheld equipment where compact size and reliability are critical
- Office Automation Equipment including printers, scanners, and copiers
- Medical Devices and laboratory equipment demanding precision and quiet operation
