SFRW156 Bearing Product Overview & Core Advantages
The SFRW156 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. Its extended inner ring facilitates easier mounting and secure axial location. This bearing is engineered to handle primarily radial loads and is suitable for a wide operating temperature range from -86 to 230 °F. With an ABEC1 tolerance class, it provides dependable performance for a variety of industrial uses.
SFRW156 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFRW156 | The base model number, indicating a specific bearing size and design series. |
| Open (Seal Type) | The bearing is unsealed, allowing for high-speed operation but requiring external lubrication and protection from contaminants. |
| Extended Inner Ring | The inner ring protrudes beyond the bearing width, simplifying installation and providing a positive locating surface. |
| ABEC1 | Denotes the precision class, specifying standard tolerances for runout and dimensions. |
| MC3 | Specifies the radial internal clearance group, which is greater than normal for applications involving thermal expansion. |
SFRW156 Bearing Structural Features & Performance Benefits
- Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments and washdown applications.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 99,000 rpm, ideal for demanding rotational applications.
- Radial Load Capacity: Engineered to efficiently carry radial loads, with a dynamic load rating of 62 lbf and a static load rating of 24 lbf.
- MC3 Internal Clearance: The specified radial internal clearance accommodates differential thermal expansion between the shaft and housing, ensuring stable performance under varying temperature conditions.
- Lightweight Design: Weighing only 0.2 grams, the bearing minimizes rotational inertia, which is critical for high-speed and precision equipment.
SFRW156 Bearing Typical Application Areas
- High-Speed Dental and Medical Handpieces
- Precision Small Motors and Spindles
- Office Automation Equipment (e.g., scanners, printers)
- Instrumentation and Control Devices
- Food Processing and Packaging Machinery (where corrosion resistance is key)
