F7-15 Bearing Product Overview & Core Advantages
The F7-15 is a metric thrust ball bearing engineered for pure axial load applications. This compact bearing features a standard inner ring and flat raceway washers, delivering reliable performance in unidirectional thrust scenarios. Its precision construction with chrome steel rings and balls ensures consistent operation and durability. The F7-15 is ideal for applications requiring high axial load capacity within minimal space constraints, making it an excellent choice for compact mechanical assemblies.
F7-15 Bearing Model Code Explained, Specifications & Naming Convention
| Code Element | Technical Meaning |
|---|---|
| F7-15 | Basic model designation indicating bearing dimensions (7mm bore, 15mm OD) |
| Open Seal | No integrated seals, requiring external lubrication and protection |
| Thrust Design | Optimized specifically for axial load direction applications |
F7-15 Bearing Structural Features & Performance Benefits
High Load Capacity: The F7-15 delivers axial dynamic load rating of 495 lbf and axial static load rating of 450 lbf, providing reliable performance in demanding thrust applications. The flat raceway washers ensure optimal load distribution across all 8 chrome steel balls.
Precision Engineering: Manufactured with tight dimensional tolerances (bore and OD tolerance: -0.008mm to 0), this bearing maintains precise alignment and smooth operation. The brass cage material provides excellent guidance for the balls while maintaining dimensional stability.
High-Speed Capability: With a limiting speed of 3,600 rpm, the F7-15 supports high-rotation applications. The optimized ball diameter of 3 mm and precise cage design contribute to balanced operation at elevated speeds.
Material Excellence: Constructed from chrome steel rings and balls, the bearing offers superior hardness and wear resistance. The compact 5 mm width and minimal 0.2 mm chamfer dimension enable integration into space-constrained designs.
F7-15 Bearing Typical Application Areas
The F7-15 thrust ball bearing is particularly suited for:
- Automotive components - steering systems, transmission assemblies
- Industrial equipment - machine tools, pumps, and compressors
- Precision instruments - optical devices, measuring equipment
- Office automation - printers, copiers, and scanners
- Medical devices - small mechanical assemblies requiring precise axial positioning
