4216 ATN9 Bearing Product Overview & Core Advantages
The 4216 ATN9 is a double row angular contact ball bearing engineered for applications requiring high rigidity and robust performance under combined loads. This precision bearing features an open design without seals, optimized for high-speed operation and efficient heat dissipation. Its compact double-row construction provides superior radial load capacity and can accommodate significant axial loads in both directions, making it an ideal solution for demanding industrial machinery where space constraints and high reliability are critical.
4216 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| A | Optimized internal design with a 30° contact angle | Enhanced axial load capacity and operational stability |
| TN9 | Nylon (polyamide) cage, glass fiber reinforced | Reduced friction, excellent for high-speed applications, and lightweight |
4216 ATN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides exceptional stiffness, enabling stable operation under heavy combined radial and axial loads. The optimized internal geometry distributes stress evenly across both ball rows.
- Superior High-Speed Performance: The TN9 nylon cage offers low mass and excellent sliding properties, contributing to lower friction and higher limiting speeds. The open structure facilitates efficient lubrication and cooling.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with a C0 radial internal clearance, ensuring consistent performance, smooth running, and precise shaft positioning.
- Durable Material Construction: Rings and balls made from high-grade chrome steel provide high fatigue resistance and long service life under demanding conditions.
