S692x 2rs Bearing Product Overview & Core Advantages
The S692x 2rs is a miniature deep groove ball bearing designed for applications demanding compact size and reliable performance. Constructed entirely from stainless steel (rings, balls, and cage) with integral rubber seals (2RS), it offers excellent corrosion resistance and protection from contaminant ingress. This single row bearing is optimized to handle primarily radial loads and is pre-lubricated for long-term, maintenance-free operation in its specified temperature range. Its small footprint, high precision (ABEC1), and robust sealing make it an ideal choice for high-reliability, compact assemblies.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S692 | The base bearing series, indicating a miniature deep groove ball bearing with a specific cross-section and internal design. |
| x | A placeholder for the bore size code, which corresponds to the 2.5 mm bore diameter. |
| 2RS | Denotes that the bearing is equipped with two rubber contact seals (one on each side). This provides superior protection against dust and moisture compared to non-contact shields. |
S692x 2rs Bearing Structural Features & Performance Benefits
- Compact and Robust Design: The single row deep groove raceway and stainless steel construction provide a robust yet lightweight solution for miniature applications, with a total weight of just 0.55 g.
- Enhanced Sealing and Contamination Resistance: The Nitrile rubber (2RS) seals make direct contact with the inner ring, effectively sealing the bearing interior. This is critical for maintaining performance and longevity in environments with potential contaminants.
- Corrosion Resistance: The use of stainless steel for all critical components ensures excellent resistance to rust and corrosion, making it suitable for applications exposed to moisture or harsh environments.
- Pre-lubricated for Maintenance-Free Operation: The bearing comes pre-filled with lubricant, enabling immediate installation and long-term, maintenance-free operation within its specified speed and temperature limits.
- Precision Performance: Manufactured to ABEC1 tolerance class and featuring a controlled MC3 radial internal clearance (0.002mm to 0.013mm), it ensures smooth and consistent running, minimizing vibration and noise.
S692x 2rs Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors, stepper motors, and coreless motors used in drones, medical devices, and robotics.
- Medical and Dental Equipment: Used in handheld surgical tools, dental handpieces, and pump mechanisms where compact size, reliability, and corrosion resistance are paramount.
- Precision Instruments and Optics: Suitable for scanners, encoders, and small gauge heads that require smooth, low-friction rotational movement.
- Office Automation and Consumer Electronics: Found in small fans, printers, and various miniature drives within compact electronic devices.
