SF602 Bearing Product Overview & Core Advantages
The SF602 is a miniature deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. As a single row radial bearing, it excels in handling primarily radial loads while offering smooth operation. Its construction from stainless steel throughout (rings, balls, and cage) provides excellent corrosion resistance, making it suitable for demanding environments. This bearing is characterized by its extremely small dimensions (2mm bore, 7mm OD) and lightweight (0.6g), ideal for space-constrained, high-speed applications up to 54,000 rpm.
SF602 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF602 | Base model number indicating a specific miniature bearing series with a 2mm bore diameter. |
| Open (Seal Type) | The bearing is unsealed, allowing for potential re-lubrication but requiring a clean operating environment. |
| ABEC1 | Specifies the precision tolerance class, suitable for many general precision applications. |
| MC3 | Denotes the radial internal clearance group (0.002mm to 0.013mm), optimized for standard operating conditions. |
SF602 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bore diameter of 2 mm and a total weight of just 0.6 grams, the SF602 is ideal for miniaturized mechanisms and applications where weight savings are critical.
- High-Speed Capability: The combination of a stainless steel cage, seven precision balls, and an open design contributes to a high limiting speed of 54,000 rpm.
- Corrosion Resistance: Manufactured entirely from stainless steel, this bearing offers superior protection against rust and corrosion, enhancing its lifespan in humid or chemically aggressive environments.
- Radial Load Capacity: Engineered to handle radial dynamic loads up to 66 lbf and static loads of 21 lbf, providing reliable performance in its size class.
- Standard Internal Clearance: The MC3 clearance group ensures smooth running and compensates for thermal expansion under normal operating temperatures.
SF602 Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical Devices: Used in surgical handpieces, dental tools, and diagnostic equipment due to its compact size and corrosion resistance.
- Office Automation: Found in scanners, printers, and small fans.
- Instrumentation & Robotics: Suitable for encoders, sensors, and small joints in robotic arms.
- Radio-Controlled Models: Commonly used in high-speed motors for drones and RC cars.
