F4-9 Bearing Product Overview & Core Advantages
The F4-9 is a metric thrust ball bearing engineered for high-precision axial load applications. This compact bearing features a chrome steel construction and open design, making it ideal for scenarios requiring high rotational accuracy and reliable performance under pure thrust loads. Its small cross-section and lightweight design (1.5 g) allow for efficient use in space-constrained assemblies.
F4-9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| F4-9 | Standard model designation for a metric thrust ball bearing with a 4 mm bore and 9 mm outside diameter. |
| Open | No seal or shield, allowing for higher limiting speeds and easy re-lubrication. |
F4-9 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: Designed specifically to accommodate thrust loads, with a dynamic load rating of 180 lbf and a static load rating of 117 lbf.
- Precision Performance: Manufactured with tight tolerances on bore diameter, outside diameter, and width for consistent and accurate operation.
- High-Speed Capability: The brass cage and open design contribute to a high limiting speed of 80,000 rpm, suitable for demanding applications.
- Durable Construction: Components made from chrome steel provide excellent wear resistance and long service life.
F4-9 Bearing Typical Application Areas
This bearing is commonly used in applications requiring management of pure axial loads, such as:
- Precision machine tool components
- Small electrical motors and gearboxes
- Office automation equipment (e.g., printers, scanners)
- Medical devices and precision instruments
- Robotics and small automation assemblies
