FRW188 Bearing Product Overview & Core Advantages
The FRW188 is a high-precision inch series ball bearing designed for demanding applications requiring reliable performance in compact spaces. As a single row deep groove ball bearing with an extended inner ring, it excels at handling radial loads while facilitating easy mounting and axial positioning. Manufactured to ABEC1 precision tolerances, this bearing offers excellent rotational accuracy and is engineered for a broad temperature range from -86 to 230 °F, making it suitable for various industrial environments.
FRW188 Bearing Model Code Explained, Specifications & Naming Convention
| Feature | Designation | Technical Significance |
|---|---|---|
| Seal Type | Open | No integral seals; allows for custom lubrication schemes and minimizes torque for high-speed operation. |
| Inner Ring | Extended | Provides a larger contact surface for secure mounting and simplifies axial location in assemblies. |
| Tolerance Class | ABEC1 | Defines standard precision grade for dimensional accuracy and runout, ensuring consistent performance. |
| Internal Clearance | MC3 | Specifies a radial internal clearance group suitable for general operating conditions. |
FRW188 Bearing Structural Features & Performance Benefits
The FRW188's performance stems from its optimized construction. The single row design with a deep groove raceway efficiently supports substantial radial dynamic loads up to 344 lbf. The extended inner ring width of 0.1562" enhances stability and provides a positive locating surface. The stainless steel cage ensures reliable ball guidance and contributes to the high limiting speed of 48,000 rpm. With a radial internal clearance of 0.00008" to 0.0005" (MC3 group), the bearing is pre-configured for a wide range of operational fits and thermal expansions. All components are crafted from chrome steel, offering high hardness and durability for long service life.
