SFRW2-6 Bearing Product Overview & Core Advantages
The SFRW2-6 is a single row ball bearing designed for high-performance applications requiring precision and reliability. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. This bearing is engineered to handle primarily radial loads and features an extended inner ring for simplified mounting and axial location. Its compact inch dimensions and ABEC1 precision make it an ideal component for compact assemblies demanding smooth operation and long service life.
SFRW2-6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFRW2-6 | The base model number, indicating a specific bearing size and design series with a 0.125" bore. |
| (No Seal Suffix) | The bearing is of open construction, meaning it has no integral seals or shields. This allows for higher limiting speeds but requires external lubrication and protection from contaminants. |
| (No Cage Suffix) | Utilizes a standard stainless steel cage to retain and space the 7 balls. |
SFRW2-6 Bearing Structural Features & Performance Benefits
Extended Inner Ring Design: The extended inner ring (inner ring width: 0.1406") facilitates easier installation and provides a positive locating surface, enhancing axial stability in the assembly.
High-Speed Capability: The open design and optimized stainless steel cage contribute to a high limiting speed of 47,700 rpm, making it suitable for demanding high-speed applications.
Corrosion Resistance: All critical components, including the rings, balls, and cage, are made from stainless steel, ensuring reliable performance in harsh or washdown environments and a wide temperature range from -86 to 230 °F.
Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), this bearing delivers consistent, low-noise, and low-vibration operation.
SFRW2-6 Bearing Typical Application Areas
The SFRW2-6 is ideally suited for a variety of precision instruments and small machinery, including:
- Small Electric Motors and spindles
- Medical and Dental Handpieces
- Precision Encoders and optical scanners
- Office automation equipment and high-speed fans
- Instrumentation and control devices
