SF602 2rs Bearing Product Overview & Core Advantages
The SF602 2RS is a miniature metric ball bearing engineered for precision applications requiring compact dimensions and reliable performance. This single row deep groove ball bearing features integral rubber seals (2RS) on both sides, providing effective protection against contamination. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its design is optimized to carry significant radial loads and is suitable for moderate speeds, making it an ideal component for applications demanding high reliability in a minimal footprint.
SF602 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF602 | The base bearing designation, indicating a specific series with a 2mm bore, 7mm outside diameter, and 3.5mm width. |
| 2RS | Denotes contact Rubber Seals on both sides of the bearing. This provides superior protection against dust and moisture ingress, extending service life. |
SF602 2rs Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The dual Nitrile Rubber (NBR) seals (2RS) effectively shield the internal components from contaminants, making the bearing suitable for harsh environments and contributing to its maintenance-free characteristics.
- Corrosion Resistance: Manufactured with stainless steel rings, cage, and balls, this bearing is inherently resistant to rust and corrosion, ensuring consistent performance and longevity.
- Precision & Smooth Operation: Built to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), this bearing ensures smooth, low-noise, and low-vibration rotation.
- Optimized Load Capacity: The deep groove raceway and 7-ball complement are designed to handle the specified dynamic and static radial load ratings effectively.
SF602 2rs Bearing Typical Application Areas
- Precision Small Motors: Ideal for small DC motors, stepper motors, and fan motors.
- Medical and Dental Devices: Used in handheld surgical tools, dental handpieces, and small pumps where reliability and corrosion resistance are critical.
- Office Automation Equipment: Suitable for printers, scanners, and copiers.
- Instrumentation and Control Systems: Applied in encoders, sensors, and small precision mechanisms.
- Radio Control Models and Small Robotics: Provides smooth rotation in joints, wheels, and drive systems.
