SFR2-6zz Bearing Product Overview & Core Advantages
The SFR2-6zz is a single row deep groove ball bearing designed for precision applications requiring reliable performance in compact spaces. Manufactured entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. A key feature is its shielded (ZZ) design, which provides effective protection against contaminant ingress while retaining lubrication. This bearing is engineered to primarily handle radial loads and is characterized by its low friction and smooth operation, making it ideal for applications demanding high rotational accuracy and long service life.
SFR2-6zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFR2-6 | Indicates the specific bearing series and size designation with a 1/8" bore. |
| zz | Signifies that the bearing is equipped with non-contact shields on both sides. This provides protection from contaminants without significantly increasing rotational torque. |
SFR2-6zz Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All critical components—inner ring, outer ring, balls, and cage—are made from stainless steel, ensuring superior corrosion resistance and durability in harsh environments.
- Effective Contaminant Protection: The ZZ shields help to retain lubricant and exclude larger particulate contaminants, enhancing bearing life and reliability in unclean operating conditions.
- Precision and Low Friction: Built to ABEC1 tolerance standards, this bearing ensures consistent performance and smooth rotation, which is critical for precision instruments.
- Optimized Internal Geometry: The deep groove raceway and complement of 7 precision balls are designed for efficient radial load carrying capacity.
- Wide Operating Temperature Range: Suitable for use from -86 to 230 °F, making it versatile for various industrial and commercial applications.
SFR2-6zz Bearing Typical Application Areas
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Motors and Gearboxes: Used in miniature DC motors, stepper motors, and precision gear mechanisms.
- Office Automation Equipment: Printers, scanners, and copiers.
- Radio Control Models and Drones: Providing reliable performance in motors and control surfaces.
- Food and Beverage Machinery: Where corrosion resistance and cleanliness are paramount.
