1207 EKTN9/C3 Bearing Product Overview & Core Advantages
The 1207 EKTN9/C3 is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and operational precision. Its double row design provides superior rigidity and stability compared to single row bearings, making it an ideal solution for supporting combined loads. Featuring a tapered bore for secure mounting and a C3 radial internal clearance for optimal performance in various thermal conditions, this bearing is built for reliability in demanding industrial environments.
1207 EKTN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 1207: Basic designation indicating a double row angular contact ball bearing with 35mm bore and 72mm outside diameter.
- EK: Designates an optimized internal design with a high-capacity ball complement and reinforced structure.
- TN9: Indicates a glass fiber reinforced polyamide (nylon) cage, contributing to high-speed performance, low friction, and quiet operation.
- C3: Specifies a greater radial internal clearance than normal (C0), suitable for applications with significant thermal expansion or where interference fits are used.
1207 EKTN9/C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing construction provides a robust and rigid support structure, effectively handling substantial radial loads. The optimized internal geometry ensures a high dynamic load rating of 4275 lbf.
High-Speed Performance: The lightweight and durable TN9 nylon cage minimizes centrifugal forces and friction, enabling a high limiting speed of 13,000 rpm. This makes the bearing suitable for high-rotation applications.
Precision & Reliability: Manufactured from high-grade chrome steel for both rings and balls, the bearing ensures long service life and consistent performance. The precision bearing dimensions and tight tolerances guarantee accurate positioning and smooth operation.
Versatile Mounting: The 1:12 tapered bore allows for precise axial positioning and secure interference fits on adapter sleeves or tapered shafts, simplifying installation and enhancing operational stability.
1207 EKTN9/C3 Bearing Typical Application Areas
The 1207 EKTN9/C3 is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery requiring robust and reliable bearing support
