SF699 2rs Bearing Product Overview & Core Advantages
The SF699 2RS is a metric single row deep groove ball bearing designed for exceptional performance in compact applications. Engineered with stainless steel construction throughout its rings, balls, and cage, it offers superior corrosion resistance. Its key advantage lies in its sealed design (2RS), which provides robust protection against contaminants while retaining lubrication, making it ideal for applications demanding high reliability and low maintenance. This bearing is optimized to handle primarily radial loads efficiently within a compact envelope.
SF699 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF699 | The basic bearing designation, indicating a specific size and internal design (9mm bore, 20mm OD). |
| 2RS | Signifies contact seals on both sides, made of Nitrile Rubber. This provides excellent sealing effectiveness for contaminated environments. |
SF699 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing & Corrosion Resistance: The double-sided Nitrile Rubber (2RS) seals effectively shield the bearing interior from dust, moisture, and other contaminants. Combined with all-stainless steel components, this ensures long service life even in harsh or washdown environments.
- High Precision & Smooth Operation: Manufactured to ABEC1 tolerance class, this bearing guarantees consistent running accuracy. The deep groove raceway and optimized geometry facilitate smooth rotation and efficient radial load support.
- Compact & Lightweight Design: With a flanged outer ring (23mm diameter), the bearing simplifies mounting and positioning in housings. Its minimal cross-section (6mm width) and low weight (9.73g) are ideal for space-constrained applications.
- Versatile Performance: The specified MC3 radial internal clearance and a limiting speed of 30,600 rpm make it suitable for a wide range of operational conditions, from moderate speeds to applications requiring precise shaft guidance.
SF699 2rs Bearing Typical Application Areas
- Small Electric Motors and Gear Motors
- Precision Instruments and Optical Devices
- Medical Equipment and Dental Handpieces
- Food Processing and Packaging Machinery (due to stainless steel construction)
- Office Automation Equipment (e.g., Printers, Scanners)
- Robotics and Small Actuators
