SF602x 2rs Bearing Product Overview & Core Advantages
The SF602x 2rs is a metric miniature deep groove ball bearing engineered for precision applications requiring compact dimensions and reliable performance. This single row bearing features integral contact seals (2RS) for effective contamination protection. Its primary function is to support radial loads efficiently. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. The bearing is pre-lubricated, ensuring immediate operation and long service life, making it an ideal choice for high-speed, compact assemblies where reliability is critical.
SF602x 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SF602x | Basic bearing series designation, indicating a miniature, flanged deep groove ball bearing with specific dimensions. | Defines the core geometry: 2.5mm bore, 8mm OD, 4mm width. |
| 2RS | Bearing is equipped with two (2) contact seals, made of Nitrile Rubber (RS), one on each side. | Provides excellent protection against dust and moisture ingress, retaining lubricant for extended service life and reduced maintenance. |
SF602x 2rs Bearing Structural Features & Performance Benefits
- Compact & Robust Flange Design: The integrated flange (9.5mm OD) simplifies mounting and positioning, providing secure axial location within a housing, which is crucial for miniature precision assemblies.
- Effective Sealing & Lubrication: The double-sided Nitrile rubber contact seals (2RS) effectively shield the internal components from contaminants. Combined with factory-applied lubrication, this creates a maintenance-free solution for the bearing's operational lifespan.
- High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to stable operation at high rotational speeds, with a limiting speed of 54,000 rpm.
- Corrosion Resistance: The all-stainless-steel construction (rings, balls, cage) ensures reliable performance in humid or mildly corrosive environments, enhancing durability.
- Precision Grade: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring consistent running accuracy and smooth operation.
SF602x 2rs Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors, stepper motors, and coreless motors.
- Medical Devices & Instrumentation: Used in surgical hand tools, dental drills, pumps, and analytical instruments due to its compact size, reliability, and corrosion resistance.
- Office Automation Equipment: Critical components in printers, scanners, and small fans.
- Robotics & Automation: Suitable for joints, actuators, and sensors in small-scale robotic systems.
- Consumer Electronics: Applied in miniature gearboxes, drones (UAVs), and high-speed cooling fans.
