SF687zz Bearing Product Overview & Core Advantages
The 6800-2Z is a metric single row deep groove ball bearing designed for exceptional reliability in compact applications. Featuring stainless steel construction and integrated shields (2Z), it offers robust radial load capacity and protection against contamination. Its small cross-section and flanged outer ring facilitate easy installation and secure positioning. This bearing is engineered for applications demanding corrosion resistance, smooth operation, and long service life where lubrication is available.
SF687zz Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 6800 | Basic bearing series designation, indicating a deep groove ball bearing with a 10mm bore and 19mm outer diameter. |
| -2Z | Signifies the bearing is equipped with non-contact steel shields on both sides. This provides effective protection against solid contaminants while minimizing friction and heat generation. |
SF687zz Bearing Structural Features & Performance Benefits
- High-Quality Stainless Steel Construction: All components, including rings, balls, and cage, are manufactured from stainless steel, providing excellent corrosion resistance and suitability for harsh environments.
- Optimized Deep Groove Raceway: The raceway geometry is designed for efficient radial load support and can accommodate minor axial loads in either direction.
- Flanged Outer Ring: The flange simplifies axial location and mounting, enhancing positional accuracy and assembly efficiency.
- Shielded Design: The 2Z shields help retain lubricant and exclude larger particulate contaminants, contributing to a longer operational life and reduced maintenance needs.
- Precision ABEC1 Class: Manufactured to ABEC1 tolerance standards, ensuring consistent performance and reliable interchangeability.
SF687zz Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Precision Instruments and Optical Devices
- Office Automation Equipment (e.g., Printers, Scanners)
- Medical and Dental Handpieces
- Food Processing and Packaging Machinery (where corrosion resistance is critical)
- Robotics and Small Actuators
