SFRW155 Bearing Product Overview & Core Advantages
The SFRW155 is a single row ball bearing designed for high-precision radial load applications. Manufactured entirely from stainless steel, it offers excellent corrosion resistance and is suitable for a wide operating temperature range from -86 to 230 °F. Its extended inner ring facilitates easier mounting and secure positioning. With an ABEC1 precision class and standardized radial internal clearance, this bearing provides reliable performance in compact, demanding environments requiring consistent operation and long service life.
SFRW155 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFRW155 | Base model number indicating a specific single row, flanged, radial ball bearing design with inch dimensions. |
| No Seal Suffix | The open (unsealed) construction allows for higher limiting speeds and custom lubrication schemes, but requires a clean operating environment or external sealing. |
SFRW155 Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single row design with an ABEC1 tolerance class ensures consistent running accuracy and stable support for shafts, minimizing vibration.
- Radial Load Capacity: Engineered to handle primarily radial loads, with a dynamic load rating of 62 lbf and a static load rating of 24 lbf.
- Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, and cage), making it ideal for applications exposed to moisture, chemicals, or requiring washdown.
- Flanged Design: The integrated flange (outer diameter: 0.359") simplifies housing design and provides secure axial location, preventing bearing creep.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 47,700 rpm.
