692 2rs Bearing Product Overview & Core Advantages
The 692 2RS is a miniature metric ball bearing engineered for compact applications demanding reliable performance. Featuring a single row design with integral rubber seals (2RS), this bearing is optimized for radial loads and offers protection against contamination. Its small footprint (2mm bore, 6mm OD, 3mm width) and ABEC1 precision make it ideal for high-speed operation up to 75,000 rpm, providing a robust solution in space-constrained, precision mechanisms.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 692 | Basic bearing series, indicating a miniature, deep groove ball bearing with specific dimension series. |
| 2RS | Bearing is fitted with contact rubber seals on both sides. The "RS" suffix denotes a nitrile rubber seal, providing effective protection against dust and moisture ingress. |
692 2rs Bearing Structural Features & Performance Benefits
- Robust Construction & Material Integrity: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing ensures high durability and corrosion resistance, supporting a long operational lifespan.
- Effective Sealing for Contamination Protection: The double-sided 2RS rubber seals effectively shield the internal components from contaminants, making the bearing suitable for environments where dust or fine particles are present. This design helps retain lubrication and extends service intervals.
- High-Speed Capability: With a limiting speed of 75,000 rpm and an optimized stainless steel cage, the bearing maintains stability and low vibration at high rotational velocities, which is critical for precision applications.
- Precision & Clearance Control: Built to ABEC1 tolerance class with an MC3 radial internal clearance (0.002mm to 0.013mm), it delivers consistent performance, reduced noise, and smooth operation, essential for sensitive mechanical systems.
692 2rs Bearing Typical Application Areas
- Small Precision Motors: Used in DC micromotors, stepper motors, and spindle motors for consumer electronics, drones, and medical devices.
- Instrumentation & Gauges: Ideal for precision measuring instruments, optical encoders, and small laboratory equipment where accuracy and compactness are paramount.
- Office Automation & IT Equipment: Commonly found in printers, scanners, small fans, and hard disk drives.
- Robotics & Miniature Actuators: Suitable for joints, gears, and small drives in robotic arms, drones, and automated small-scale machinery.
