F2X-7 Bearing Product Overview & Core Advantages
The F2X-7 is a metric thrust ball bearing engineered for precision axial load applications. This miniature bearing features a compact design with a 2.5 mm bore, making it ideal for space-constrained assemblies requiring high precision. Its primary function is to accommodate pure thrust loads in one direction while offering smooth operation. Manufactured from chrome steel with a brass cage, it delivers reliable performance and durability in demanding conditions, compliant with ROHS and REACH standards.
F2X-7 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| F2X-7 | Model designation indicating a thrust ball bearing series with specific dimensions. |
| Open (Seal Type) | No seals or shields, allowing for higher speed capability but requiring a clean operating environment or external sealing. |
| Flat Raceway | The washers feature a flat raceway design, optimized for handling thrust loads. |
F2X-7 Bearing Structural Features & Performance Benefits
- High Precision & Compact Design: With a bore diameter of 2.5 mm and an outside diameter of 7 mm, this bearing offers a minimal cross-section, perfect for miniaturized precision instruments.
- Superior Thrust Load Capacity: Designed specifically for axial dynamic loads (rated 35 lbf) and axial static loads (rated 26 lbf), ensuring reliable performance in thrust applications.
- Optimized High-Speed Performance: The brass cage provides excellent guidance for the six precision balls, contributing to stable operation and a limiting speed of 15,000 rpm.
- Material Durability: Components made from chrome steel (rings and balls) offer high hardness and wear resistance, while the brass cage ensures low friction and dimensional stability.
- Wide Operating Range: Suitable for a temperature range from -30°C to 110°C, accommodating various industrial environments.
F2X-7 Bearing Typical Application Areas
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment where miniature size and accurate axial positioning are critical.
- Small Motors and Actuators: Used in stepper motors, miniature DC motors, and precision actuators to manage thrust loads.
- Office Automation Equipment: Printers, scanners, and copiers that require compact, high-speed thrust bearings.
- Electronic Devices: Cooling fans, small pumps, and robotics applications utilizing miniature bearings for axial support.
