SFR1810 2rs Bearing Product Overview & Core Advantages
The SFR1810 2RS is a precision miniature ball bearing engineered for demanding applications requiring compact size and reliable performance. As a single row deep groove ball bearing, it is primarily designed to handle radial loads efficiently. Its key advantages include a sealed design for contamination protection, construction from corrosion-resistant stainless steel, and compliance with ABEC1 precision standards. This combination makes it an ideal solution for applications where space is limited, and consistent operation is critical.
SFR1810 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFR1810 | Basic bearing designation indicating the inch series size (Bore: 0.3125", OD: 0.5", Width: 0.1562"). |
| 2RS | Signifies that the bearing is equipped with two rubber seals (RS), one on each side. This provides effective protection against contaminants and helps retain lubrication. |
SFR1810 2rs Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The dual Nitrile rubber seals (2RS) effectively shield the internal components from dust, moisture, and other contaminants, significantly enhancing bearing life and reliability in harsh environments.
- Corrosion Resistance: Manufactured entirely from stainless steel for the rings, balls, and cage, this bearing offers excellent resistance to corrosion, making it suitable for applications exposed to moisture or chemicals.
- Precision Performance: Built to ABEC1 tolerance class, it ensures smooth and quiet operation with reduced vibration, which is essential for high-speed applications (limiting speed of 36,000 rpm).
- Optimized Internal Geometry: Features 12 precision balls for balanced load distribution and smooth rotation. The standard radial internal clearance (MC3) is suitable for a wide range of operating conditions.
- Compact & Lightweight: With a slim width of 0.1562" and a low weight of 1.72 grams, it is ideal for space-constrained miniature assemblies.
SFR1810 2rs Bearing Typical Application Areas
This versatile miniature sealed bearing is commonly specified in:
- Precision Instruments: Medical devices, optical encoders, and laboratory equipment.
- Small Motors and Gearboxes: Stepper motors, servo motors, and miniature DC motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Robotics and Automation: Small robotic joints, conveyor rollers, and positioning stages.
- Consumer Electronics: Drones, computer cooling fans, and high-end hobbyist projects.
