S683 2rs Bearing Product Overview & Core Advantages
The S683 2RS is a miniature sealed deep groove ball bearing designed for applications requiring compact size, corrosion resistance, and reliable performance. Constructed entirely from stainless steel and featuring integral rubber seals (2RS), this single row bearing is engineered to handle primarily radial loads while offering protection from contamination. Its small footprint, with a 3mm bore and 7mm outside diameter, makes it ideal for high-precision, space-constrained mechanisms. The bearing is pre-lubricated, contributing to its low maintenance and long service life in demanding environments.
S683 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| S683 | The base bearing designation, indicating a specific series of miniature metric bearings. | Defines the core bearing dimensions (3x7x3mm). |
| 2RS | Bearing is equipped with contact rubber seals on both sides. | Provides excellent protection against dust, moisture, and other contaminants, retaining lubricant for extended life. |
S683 2rs Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh or wash-down environments.
- Robust Sealing: The Nitrile Rubber (NBR) seals (2RS) effectively shield the internal components, preventing lubricant loss and the ingress of contaminants, which is critical for maintaining performance and longevity.
- Optimized for Miniature Applications: With a compact bearing size of 3x7x3mm and a low weight of 0.45g, it delivers reliable performance in small-scale precision equipment.
- Precision & Smooth Operation: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3), ensuring consistent and smooth running characteristics.
S683 2rs Bearing Typical Application Areas
This bearing is ideally suited for a wide range of small, precision devices, including:
- Small Precision Motors and Stepper Motors
- Medical and Dental Hand Tools
- Optical Encoders and Instrumentation
- RC Models and Drones
- Office Automation Equipment (e.g., small printers, scanners)
- Precision Gearboxes and Small Mechanisms
