1307 ETN9/C3 Bearing Product Overview & Core Advantages
The 1307 ETN9/C3 is a double row angular contact ball bearing designed for demanding applications requiring high radial load capacity and operational stability. This precision bearing features an open design with a nylon cage and is pre-lubricated for immediate use. Its double row construction provides high rigidity and is capable of accommodating combined loads, making it an ideal solution for compact arrangements where superior performance and reliability are critical.
1307 ETN9/C3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 1307 ETN9/C3 breaks down as follows:
- 1307: Basic designation indicating a double row angular contact ball bearing with a 35mm bore.
- E: Denotes optimized internal design for enhanced load capacity.
- TN9: Signifies the cage material and type. "T" indicates a phenolic resin (textile) cage, and "N9" specifies a design suitable for high-speed operation.
- C3: Indicates a radial internal clearance greater than normal (CN), suitable for applications with thermal expansion or where interference fits are used.
1307 ETN9/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement provides superior radial stiffness and enables the bearing to support significant radial dynamic loads (5962 lbf) and radial static loads (1912 lbf).
- High-Speed Performance: The lightweight TN9 nylon cage ensures stable operation and contributes to the high limiting speed of 11,000 rpm, reducing centrifugal forces and friction.
- Optimized Internal Clearance: The C3 clearance group allows for thermal expansion in the shaft and housing, preventing preload and ensuring smooth operation across a wide temperature range (-30°C to 110°C).
- Pre-Lubricated & Ready-to-Use: Factory-applied lubrication ensures immediate operation and reduces initial maintenance requirements.
1307 ETN9/C3 Bearing Typical Application Areas
This bearing is commonly specified in:
- Electric Motors and Generators
- Industrial Gearboxes
- Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
