4212 ATN9 Bearing Product Overview & Core Advantages
The 4212 ATN9 is a double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance under combined loads. Its metric design features a 60 mm bore, 110 mm outside diameter, and 28 mm width, providing a compact solution for robust machinery. Constructed with open seal type and precision ABEC-1 tolerance class, this bearing delivers exceptional radial load capacity (dynamic: 12,870 lbf, static: 12,375 lbf) while maintaining dimensional stability. The optimized nylon cage and high-speed capability (limiting speed: 9,500 rpm) make it ideal for demanding industrial environments where precision and durability are critical.
4212 ATN9 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 4212 | Standard bearing series designation indicating bore diameter (60 mm) and dimensional series |
| A | Contact angle optimized for combined radial and axial load handling |
| TN9 | Nylon cage construction enabling high-speed operation and reduced friction |
4212 ATN9 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness and stability, effectively handling combined radial and axial loads in both directions. This makes the bearing particularly suitable for applications requiring precise shaft positioning.
Enhanced Load Capacity: With a radial dynamic load rating of 12,870 lbf and static rating of 12,375 lbf, this bearing delivers reliable performance under substantial operational stresses while maintaining C0 radial internal clearance (0.008-0.028 mm) for optimal fit and performance.
High-Speed Performance: The TN9 nylon cage minimizes centrifugal forces and friction, enabling a limiting speed of 9,500 rpm. This makes the bearing suitable for high-rotation applications without compromising structural integrity.
Material Excellence: Manufactured from chrome steel for both rings and balls, the bearing offers excellent wear resistance and durability across a wide temperature range (-30° to 110°C).
