S694 2rs Bearing Product Overview & Core Advantages
The S694 2RS is a metric, single row deep groove ball bearing designed for high-performance applications requiring reliability and compact design. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its key advantage lies in its integrated Nitrile rubber seals (2RS), which effectively retain lubrication and exclude contaminants, making it a robust, pre-lubricated solution for radial loads in demanding environments. This combination ensures long service life and consistent operation within its specified temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S694 | The base bearing designation, indicating a specific series of miniature deep groove ball bearings with a 4mm bore, 11mm OD, and 4mm width. |
| 2RS | Denotes that the bearing is fitted with contact seals on both sides. The "RS" suffix specifies Nitrile rubber seals, providing superior protection against contamination and moisture. |
S694 2rs Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The double-sided Nitrile rubber (2RS) seals are the cornerstone of this bearing's durability. They provide excellent protection, making the bearing suitable for environments with dust or moisture, and ensure the pre-applied lubricant is retained for long-term, maintenance-free operation.
- High-Grade Material: The use of stainless steel for all critical components (rings, balls, cage) guarantees high corrosion resistance and enables reliable performance across a wide temperature range from -30°C to 110°C.
- Precision & Load Capacity: Manufactured to ABEC1 tolerance standards, this bearing offers reliable running accuracy. With a radial dynamic load rating of 165 lbf and a radial static load rating of 57 lbf, it is engineered to handle significant radial loads for its compact size.
- Optimized Internal Geometry: The deep groove raceway and the complement of 7 precision stainless steel balls work in concert to support high-speed operation, with a limiting speed of 43,200 rpm, making it an excellent choice for high-speed applications.
S694 2rs Bearing Typical Application Areas
This bearing is ideally suited for compact, high-speed, and corrosion-sensitive applications, including:
- Precision Small Motors: Such as those used in drones, RC models, and small fans.
- Medical and Dental Handpieces: Where reliability, speed, and corrosion resistance are critical.
- Office Automation Equipment: Including small printers, scanners, and copiers.
- Instrumentation and Control Systems: For precise rotary motion in gauges and sensors.
- Food Processing and Packaging Machinery: Benefiting from its stainless steel construction and sealed design.
