1210 EKTN9/C3W64 Bearing Product Overview & Core Advantages
The 1210 EKTN9/C3W64 is a metric double row angular contact ball bearing engineered for applications requiring high precision and robust performance. Featuring a tapered bore (1:12) and open design, this bearing is optimized for handling significant radial loads while maintaining dimensional stability. Its double-row construction provides high rigidity and compactness, making it ideal for high-reliability machinery where space constraints and precise shaft positioning are critical. Pre-lubricated and featuring a C3 radial internal clearance, it ensures reliable operation under varying thermal conditions.
Model Code Detailed Breakdown
| Suffix Code | Technical Meaning | Performance Implication |

| EK | Optimized internal design with reinforced shoulders | Enhanced load capacity and structural integrity |
| TN9 | Nylon cage, glass fiber reinforced | Reduced friction, suitable for high-speed applications |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in precision assemblies |
| W64 | Bearing with solid oil lubrication | Maintenance-free operation, extended service life |
1210 EKTN9/C3W64 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides superior stiffness, enabling the bearing to handle substantial radial loads (dynamic: 5962 lbf, static: 2059 lbf) while maintaining precise alignment. The tapered bore ensures secure mounting on tapered shafts, enhancing system stability.
Optimized High-Speed Performance: The TN9 nylon cage minimizes centrifugal forces and reduces friction, supporting limiting speeds up to 10,000 rpm. Combined with solid oil lubrication (W64), it ensures consistent performance at high rotational velocities.
Precision & Thermal Management: Manufactured from chrome steel with strict dimensional tolerances (bore: -0.012mm to 0), this bearing offers precise running accuracy. The C3 clearance accommodates thermal expansion, making it suitable for applications with operating temperatures from -30°C to 110°C.
Maintenance-Free Operation: Pre-lubricated with solid oil, the bearing requires no relubrication, reducing maintenance needs and ensuring long-term reliability in sealed or hard-to-access environments.
