1212TN Bearing Product Overview & Core Advantages
The 1212TN is a double row angular contact ball bearing designed for applications requiring high rigidity and the ability to handle combined loads. Its metric construction features a 60 mm bore diameter and 110 mm outside diameter, providing a compact solution for space-constrained installations. Manufactured from chrome steel with a nylon cage, this precision bearing delivers reliable performance in demanding environments while maintaining dimensional stability across its operating temperature range of -30° to 110°C.
1212TN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| TN | Nylon cage, injection molded, providing excellent high-speed performance and reduced friction |
| Open | No seals, allowing for optimal lubrication access and maximum speed capability |
| CN | Normal radial internal clearance, suitable for most operating conditions |
1212TN Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, making it ideal for applications requiring minimal deflection under load.
Enhanced Load Capacity: Engineered to handle significant radial loads (7020 lbf dynamic rating) while accommodating moderate axial loads in both directions, making it suitable for combined loading scenarios.
Optimized High-Speed Performance: The nylon TN cage reduces rotational mass and friction, enabling operation at limiting speeds up to 8,000 rpm while maintaining stability.
Precision Engineering: Manufactured with tight dimensional tolerances (bore and OD tolerance: -0.015mm to 0) ensuring consistent performance in precision applications.
