FRW3 Bearing Product Overview & Core Advantages
The FRW3 is a single row ball bearing designed for high-performance applications requiring reliable radial load capacity. Manufactured to ABEC1 precision tolerances, this bearing features an extended inner ring for simplified mounting and secure axial location. Its open design allows for versatile lubrication options, making it suitable for a wide operating temperature range from -86 to 230 °F. The use of chrome steel rings and balls, combined with a stainless steel cage, ensures durability and consistent operation, offering an excellent balance of performance and value for demanding industrial environments.
FRW3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| FRW3 | The base designation for this specific flanged bearing series with an extended inner ring. |
| Open (Seal Type) | No integral seals or shields. Allows for high-speed operation and custom lubrication schemes. |
| ABEC1 | Defines the precision tolerance class, ensuring controlled runout and smooth operation. |
| MC3 | Specifies the radial internal clearance group (0.00008" to 0.0005"), optimized for general operating conditions. |
FRW3 Bearing Structural Features & Performance Benefits
- Extended Inner Ring & Flange Design: The extended inner ring facilitates easier installation and axial positioning. The integral flange (0.565" diameter) provides secure mounting into a housing, preventing lateral movement and simplifying assembly.
- Optimized Load Capacity: With a dynamic load rating of 249 lbf and a static load rating of 88 lbf, this bearing is engineered to handle significant radial loads in compact spaces.
- High-Speed Capability: The lightweight stainless steel cage and open construction contribute to a high limiting speed of 110,000 rpm, making it suitable for demanding rotational applications.
- Precision Engineering: The chrome steel components and ABEC1 tolerances ensure low vibration and minimal operational noise, enhancing the lifespan of the application.
- Versatile Lubrication: The open seal type requires lubrication but offers the flexibility to use greases or oils best suited for the specific application's speed and temperature requirements.
FRW3 Bearing Typical Application Areas
This flanged ball bearing is ideal for applications where space is constrained and reliable radial support is critical. Common uses include:
- Small Electric Motors and Gearboxes
- Precision Spindles in Dental and Medical Handpieces
- Office Automation Equipment (e.g., Printers, Scanners)
- Cooling Fans and Blowers
- Instrumentation and Control Devices
