6802zz Bearing Product Overview & Core Advantages
The 6802zz is a single row deep groove ball bearing designed for exceptional performance in compact spaces. This shielded bearing offers reliable operation and is engineered to handle primarily radial loads with high efficiency. Its metric dimensions, precision ABEC-1 tolerance class, and robust construction using chrome steel components make it a dependable choice for applications demanding high reliability and long service life. The pre-lubricated design ensures immediate readiness for installation and operation.
6802zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| zz | Non-contact steel shields on both sides | Provides effective protection against contamination while minimizing friction, contributing to the high limiting speed. |
| N/A* | Standard C0 radial internal clearance | Ensures stable operation under normal operating conditions and temperatures. |
*The base 6802 model with 'zz' suffix implies standard C0 clearance and standard grease lubrication unless otherwise specified.
6802zz Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & High-Capacity Design: The deep, continuous raceways on both rings are optimized to support significant radial dynamic and static loads, making it a versatile ball bearing for various mechanical systems.
- Effective Contamination Protection: The non-contact steel shields (zz) effectively guard the internal components from dust and other particulates, enhancing bearing life and reliability without a significant penalty on speed.
- High-Speed Capability: The combination of a stainless steel cage, precision-ground chrome steel balls and rings, and optimized internal geometry allows for a high limiting speed of 31,000 rpm.
- Precision & Consistency: Manufactured to ABEC-1 precision class standards, this bearing ensures smooth, quiet, and vibration-reduced operation, which is critical for the performance of precision equipment.
6802zz Bearing Typical Application Areas
The 6802zz is ideally suited for a wide range of applications where compact size, reliability, and moderate to high speeds are required. Key sectors include:
- Electric Motors: Small to medium-sized motors for appliances, power tools, and fans.
- Precision Instruments: Optical encoders, medical devices, and measuring equipment.
- Office Automation: Printers, scanners, and copiers.
- Small Machinery: Pumps, gearboxes, and light-duty power transmission systems.
