683 2rs Bearing Product Overview & Core Advantages
The 683 2RS is a metric miniature deep groove ball bearing engineered for compact applications requiring reliable performance. Featuring a single row design and integral rubber seals (2RS), this bearing is optimized for radial load applications and offers protection against contamination. Its small bore diameter of 3mm and overall compact dimensions make it an ideal choice for high-precision, space-constrained assemblies where consistent operation is critical.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 683 | The basic bearing series, indicating a miniature deep groove ball bearing with a 3mm bore, 7mm OD, and 3mm width. |
| 2RS | Denotes that the bearing is sealed on both sides with Nitrile Rubber (Buna-N) seals. This provides effective protection against dust and moisture, retaining lubricant for extended service life. |
683 2rs Bearing Structural Features & Performance Benefits
- Robust Construction & Material Integrity: Manufactured from Chrome Steel for rings and balls with a Stainless Steel cage, this bearing offers excellent resistance to wear and corrosion, ensuring long-term dimensional stability.
- Effective Sealing for Contaminant Exclusion: The double-sided rubber seals (2RS) shield the internal components from particulate and fluid contaminants, making the bearing suitable for environments where cleanliness is a factor. This sealing also helps to retain the factory-applied lubricant.
- Precision & Smooth Operation: Built to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), the 683 2RS provides reliable and smooth running characteristics, which is essential for miniature and precision applications.
- Optimized Load and Speed Capacity: With a dynamic load rating of 59 lbf and a limiting speed of 63,000 rpm, this bearing is capable of handling significant radial loads at high rotational speeds for its size.
683 2rs Bearing Typical Application Areas
- Small Electric Motors: Ideal for use in miniature DC motors, stepper motors, and fan motors.
- Precision Instruments & Optical Devices: Used in encoders, scanners, and laboratory equipment where small size and reliability are paramount.
- Office Automation Equipment: Commonly found in printers, copiers, and small drives.
- Radio-Control Models & Hobbyist Projects: Suitable for drones, miniature vehicles, and other compact mechanical systems.
- Medical Devices: Applied in small, portable medical instruments and diagnostic equipment.
