FR0 Bearing Product Overview & Core Advantages
The FR0 series represents a precision miniature ball bearing designed for demanding applications requiring compact dimensions and reliable performance. As a single row radial ball bearing with an open design, it excels in handling radial loads efficiently. Its inch-system sizing and ABEC1 tolerance class ensure consistent quality and interchangeability, making it an ideal component for high-speed mechanisms where space is at a premium and operational reliability is critical.
FR0 Bearing Model Code Explained, Specifications & Naming Convention
| Feature | Code/Value | Technical Significance |
|---|---|---|
| System of Measurement | Inch | Designed for imperial system applications and replacements. |
| Seal Type | Open | Allows for custom lubrication schemes but requires a clean operating environment. |
| Tolerance Class | ABEC1 | Defines standard precision levels for runout and dimensional consistency. |
| Internal Clearance | MC3 | Specifies a radial internal clearance group suitable for a wide range of operating conditions. |
FR0 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bore diameter of 0.046875" and a total weight of just 0.12 g, this bearing is engineered for applications with severe space and weight constraints.
- High-Speed Capability: The combination of a stainless steel cage, 7 high-precision chrome steel balls, and an open structure contributes to a high limiting speed of 110,000 rpm.
- Robust Load Capacity: The single row construction is optimized to handle the specified radial dynamic load rating of 21 lbf and radial static load rating of 6 lbf effectively.
- Material Integrity: Components made from chrome steel offer excellent hardness and wear resistance, ensuring long service life under standard operating conditions within a temperature range of -86 to 230 °F.
FR0 Bearing Typical Application Areas
This miniature ball bearing is ideally suited for:
- Small Precision Motors and stepper motors
- Medical devices and surgical handpieces
- Optical encoders and instrumentation
- High-speed spindles in dental drills
- Office automation equipment and small fans
- Robotics and miniature gearboxes
