1210TNC3 Bearing Product Overview & Core Advantages
The 1210TNC3 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance under combined radial and axial loads. Its open design with a C3 radial internal clearance makes it suitable for operational conditions where thermal expansion must be accommodated. Featuring a nylon cage and pre-lubrication, this bearing delivers smooth operation and is ideal for precision machinery demanding consistent performance.
1210TNC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1210 | Bore diameter: 50 mm, Outside diameter: 90 mm, Width: 20 mm |
| TN | Nylon cage (Polyamide) for reduced friction and quieter operation |
| C3 | Greater than normal radial internal clearance for high-temperature applications |
1210TNC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing construction provides superior rigidity and can handle significant combined radial and axial loads simultaneously, making it ideal for applications with complex loading conditions.
Optimized Speed Performance: The lightweight nylon cage (TN) reduces centrifugal forces, enabling higher operational speeds while maintaining stability and reducing vibration.
Thermal Compensation: The C3 clearance allows for thermal expansion during operation, preventing binding and ensuring consistent performance across the specified temperature range (-30° to 110°C).
Precision Engineering: Manufactured from chrome steel for both rings and balls, this bearing ensures durability and long service life under demanding conditions.
