S682x 2rs Bearing Product Overview & Core Advantages
The S682x 2rs is a miniature deep groove ball bearing designed for applications requiring compact dimensions and reliable performance. As a single row, sealed metric bearing, it excels in handling radial loads with high efficiency. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance, making it ideal for demanding environments. Its small bore diameter of 2.5 mm and lightweight design (0.2 g) are perfect for space-constrained, high-speed applications such as miniature motors and precision instruments.
S682x 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S682 | Basic bearing series designation, indicating a miniature deep groove ball bearing with a specific dimension series. |
| x | Placeholder for the bore diameter code. For a 2.5 mm bore, this is typically a specific numerical identifier. |
| 2RS | Signifies that the bearing is fitted with two rubber seals (RS), one on each side. This provides effective protection against contamination and retains lubricant, enhancing service life. |
S682x 2rs Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The dual Nitrile Rubber (NBR) seals (2RS) effectively shield the internal components from dust, moisture, and other contaminants. This design supports a maintenance-free operation in many applications by retaining the factory-applied lubrication.
- High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to smooth operation and a high limiting speed of 63,900 rpm, making it suitable for demanding high-speed scenarios.
- Corrosion Resistance & Durability: Manufactured entirely from stainless steel, this bearing is highly resistant to rust and corrosion, ensuring reliable performance in humid or chemically aggressive environments.
- Precision & Stability: Built to ABEC1 tolerance class with a controlled MC3 radial internal clearance (0.002mm to 0.013mm), it provides consistent and precise running performance, minimizing vibration and noise.
S682x 2rs Bearing Typical Application Areas
The S682x 2rs is engineered for a wide range of compact and precision-driven applications, including:
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical and Dental Handpieces: Used in tools requiring high-speed rotation, sterility, and reliability.
- Optical and Precision Instruments: Suitable for scanners, encoders, and measuring devices where low noise and smooth operation are critical.
- Office Automation Equipment: Commonly found in printers, copiers, and small fans.
- Radio-Controlled Models and Drones: Provides high-performance support in motor and gearbox assemblies.
