F3-8M Bearing Product Overview & Core Advantages
The F3-8M is a metric thrust ball bearing engineered for applications requiring precise axial load handling in compact spaces. Designed with a grooved raceway on both washers, it efficiently accommodates pure thrust loads along a single axis. Its open design allows for customizable lubrication strategies, while the brass cage ensures stable ball guidance, making it suitable for high-speed operation up to 11,000 rpm. This bearing is ideal for applications demanding high precision, minimal cross-section, and reliable performance in thrust-oriented mechanisms.
F3-8M Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| F3 | Indicates the bearing series and size classification |
| 8M | Specifies metric dimensions with 8mm outside diameter |
| Open | No seals or shields, allowing for custom lubrication |
| Thrust | Designed exclusively for axial load applications |
F3-8M Bearing Structural Features & Performance Benefits
Optimized Load Capacity: Features grooved raceways on both shaft and housing washers, enabling efficient handling of pure axial loads with dynamic rating of 135 lbf and static rating of 108 lbf.
High-Speed Capability: The brass cage provides excellent ball guidance and stability, supporting limiting speeds up to 11,000 rpm while maintaining operational precision.
Precision Engineering: Manufactured with chrome steel rings and balls, ensuring high dimensional stability with tight tolerances (bore diameter tolerance: -0.008mm to 0).
Compact Design: With only 3.5mm width and 8mm outside diameter, it delivers maximum performance in minimal space, ideal for compact assembly requirements.
