1307TN Bearing Product Overview & Core Advantages
The 1307TN is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loading conditions. This metric bearing features an open design without integral seals, making it suitable for systems where external sealing is provided or where maximum speed is critical. Its double row construction provides excellent radial load capacity and can accommodate significant axial loads in both directions simultaneously. With precision chrome steel components and a nylon cage, the 1307TN delivers smooth operation and is pre-lubricated for immediate use, offering an optimal balance of performance and durability in high-speed applications.
1307TN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1307 | Standard bearing designation indicating 35mm bore diameter, 80mm outside diameter, and 21mm width |
| TN | Nylon cage (polyamide) design offering reduced weight, quiet operation, and excellent performance at high speeds |
1307TN Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, making it ideal for applications requiring precise shaft positioning and minimal deflection under load.
Enhanced Load Capacity: Engineered to handle significant combined radial and axial loads from both directions, this bearing eliminates the need for complex bearing arrangements in many applications.
Optimized High-Speed Performance: The TN nylon cage reduces rotational mass and provides excellent guidance, contributing to the bearing's limiting speed of 11,000 rpm. The open design minimizes friction and heat generation at high velocities.
Precision Manufacturing: Manufactured with chrome steel rings and balls to exacting tolerances, ensuring consistent performance and long service life. The CN radial internal clearance provides optimal preload conditions for most applications.
Immediate Operation Ready: Factory pre-lubricated for out-of-the-box installation and operation within the specified temperature range of -30°C to 110°C.
