1210 EKTN9/C3 Bearing Product Overview & Core Advantages
The 1210 EKTN9/C3 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and the ability to handle combined loads. Its double row design provides superior radial and axial load capacity in a compact footprint. Featuring a tapered bore and a C3 radial internal clearance, this bearing is optimized for precision mounting and stable operation under varying thermal conditions. The inclusion of a nylon cage (TN9) and factory-applied lubrication ensures reliable high-speed performance, making it an ideal solution for demanding industrial machinery.
1210 EKTN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 1210 | Standard bore diameter (50 mm) and series designation. | Standardized bearing dimensions for easy interchangeability. |
| EK | Optimized internal design and pressed steel cage (superseded by TN9 in this model). | Enhanced load capacity and speed capability. |
| TN9 | Nylon (polyamide) cage, glass fiber reinforced. | Reduced friction, lower weight, and excellent performance at high speeds. |
| C3 | Radial internal clearance greater than Normal (CN) group. | Accommodates thermal expansion in applications, preventing preload and ensuring operational stability. |
1210 EKTN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide significantly higher radial dynamic load rating (5962 lbf) and stiffness compared to single row bearings, effectively managing combined loads.
- Tapered Bore for Precision Mounting: The 1:12 taper allows for precise axial positioning and secure interference fit on adapter sleeves or tapered shafts, critical for applications like spindle supports.
- Optimized High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces and inertial drag, while the factory-applied lubrication ensures smooth operation up to the limiting speed of 10,000 rpm.
- Stable Thermal Operation: The specified C3 clearance provides operational reliability by compensating for differential thermal expansion between the bearing rings and the housing/shaft, preventing seizure or excessive preload.
1210 EKTN9/C3 Bearing Typical Application Areas
This precision bearing is ideally suited for a wide range of industrial machinery where high rigidity, speed, and reliability are paramount. Key applications include:
- Machine Tool Spindles
- Industrial Gearboxes
- Pumps and Compressors
- Electric Motors
- Material Handling Equipment
