4207 ATN9 Bearing Product Overview & Core Advantages
The 4207 ATN9 is a double row angular contact ball bearing designed for applications requiring high radial load capacity and compact design. This precision bearing features an open construction without seals, allowing for optimal lubrication management in controlled environments. Its double row configuration provides high rigidity and stable operation, making it suitable for machinery where precise shaft positioning is critical. Manufactured to ABEC-1 tolerance standards, it delivers reliable performance for general precision applications.
Model Code Deep Explanation
| Code Segment | Technical Meaning |
|---|---|
| 4207 | Basic bearing designation indicating 35mm bore, 72mm OD, 23mm width |
| A | Contact angle of 30°, optimized for combined radial and axial loads |
| TN9 | Nylon cage (polyamide) design for reduced weight and smooth operation at high speeds |
4207 ATN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design with 30° contact angle provides exceptional stiffness and radial load capacity (7,898 lbf dynamic rating), enabling stable operation under significant radial forces.
Optimized High-Speed Performance: The lightweight nylon cage (TN9) reduces centrifugal forces and ensures smooth rotation at limiting speeds up to 15,000 rpm, making it ideal for high-speed applications.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with controlled radial internal clearance (C0) for consistent performance and precise shaft guidance.
Material Excellence: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability across the operating temperature range of -30° to 110°C.
4207 ATN9 Bearing Typical Application Areas
This bearing is widely used in:
- Industrial gearboxes and transmission systems
- Electric motors and spindle drives
- Material handling equipment and conveyor systems
- Agricultural machinery and implements
- General industrial machinery requiring reliable radial support
The combination of double row design, high radial capacity, and bearing dimensions (35×72×23mm) makes it particularly suitable for compact arrangements where space constraints exist.
