4315 ATN9 Bearing Product Overview & Core Advantages
The 4315 ATN9 is a double row angular contact ball bearing engineered for demanding applications requiring high load capacity and robust performance. This precision bearing is designed to accommodate significant combined loads—both radial and axial forces—within a single, compact unit. Manufactured to ABEC-1 tolerance standards, it ensures reliable operation and dimensional consistency. Its open design and nylon cage contribute to its suitability for high-speed operation, making it an excellent choice for industrial machinery where high rigidity and dependable performance are critical.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 4315 | Standard bearing series designation, indicating the bearing dimensions (75mm bore, 160mm OD, 55mm width). |
| A | Contact angle of 30 degrees, optimized for carrying substantial axial loads in addition to radial loads. |
| TN9 | Nylon (polyamide) cage, glass fiber reinforced. This design reduces friction, weight, and inertia, enabling higher limiting speeds and excellent acceleration characteristics. |
4315 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides a rigid support system, significantly increasing the bearing's ability to handle heavy combined loads and moment loads compared to single row designs.
- Optimized for High Speeds: The lightweight TN9 nylon cage minimizes centrifugal forces, reduces friction, and allows for smoother operation at the high limiting speed of 6,700 rpm.
- Precision Engineering: Manufactured from high-grade chrome steel for both rings and balls, ensuring durability and long service life under demanding conditions. The ABEC-1 tolerance class guarantees consistent and precise running accuracy.
- Standard Internal Clearance: The C0 radial internal clearance (0.01mm to 0.03mm) is suited for most common industrial applications, providing stable operation under normal operating temperatures and fits.
4315 ATN9 Bearing Typical Application Areas
The 4315 ATN9 is ideally suited for a wide range of industrial machinery and equipment, including:
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Electric Motors
- General Industrial Machinery requiring robust and reliable bearing solutions.
