S697 2rs Bearing Product Overview & Core Advantages
The S697 2RS is a metric single row deep groove ball bearing engineered for precision applications requiring reliable performance. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS) with nitrile rubber contact seals on both sides, which effectively retain lubricant and exclude contaminants, making it suitable for low-maintenance operation. This bearing is designed to primarily handle radial loads and is characterized by its compact dimensions (7mm bore, 17mm OD, 5mm width), making it ideal for applications where space is limited and reliability is critical.
S697 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S697 | The basic bearing designation, indicating a specific size and series of a single row deep groove ball bearing. |
| 2RS | Denotes two integral nitrile rubber (NBR) contact seals, one on each side. This provides superior protection against contamination and grease leakage compared to non-contact shields. |
S697 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing: The double-sided RS seals ensure a high degree of protection, making the bearing suitable for environments with dust or moisture, thereby enhancing service life and reliability.
- Corrosion Resistance: The all-stainless-steel construction (AISI 440 cage) provides excellent resistance to rust and corrosion, ideal for applications exposed to harsh or washdown environments.
- Precision & Quiet Operation: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance, this bearing offers consistent performance, low noise, and smooth rotation for precision instruments and small machinery.
- Optimized Load Capacity: With a dynamic load rating of 276 lbf and a static load rating of 117 lbf, it is well-suited for the radial loads encountered in compact assemblies.
- Temperature Compatibility: The standard lubrication and nitrile rubber seals are effective within an operating temperature range of -30°C to 110°C.
S697 2rs Bearing Typical Application Areas
- Precision instruments and measuring devices
- Small electric motors and gear motors
- Office automation equipment (e.g., printers, scanners)
- Medical and dental handpieces
- Food processing machinery (where corrosion resistance is beneficial)
- Radio control models and small hobbyist machinery
