1207TNC3 Bearing Product Overview & Core Advantages
The 1207TNC3 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. This precision bearing features an open design with optimized internal geometry, enabling it to accommodate significant radial loads along with axial loads in both directions simultaneously. Its compact construction and high rigid double row arrangement make it ideal for space-constrained applications demanding precise rotational accuracy and long service life in various industrial environments.
1207TNC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Impact |
|---|---|---|
| 1207 | Standard metric size designation (35mm bore, 72mm OD) | Standardized bearing dimensions for easy replacement |
| TN | Nylon cage construction | Reduced friction, suitable for high-speed applications |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature operations |
1207TNC3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row angular contact configuration provides superior stiffness compared to single row bearings, making it exceptionally stable under heavy combined loads and minimizing deflection in precision applications.
Enhanced Load Capacity: Engineered to handle substantial radial loads while simultaneously supporting bidirectional axial loads, this bearing offers versatile load-carrying capabilities in compact bearing dimensions (35mm bore × 72mm OD × 17mm width).
Optimized High-Speed Performance: The nylon cage (TN) reduces rotational mass and friction, contributing to the bearing's impressive limiting speed of 13,000 rpm. The open design facilitates efficient lubrication distribution for sustained high-speed operation.
Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing ensures consistent performance and durability. The C3 radial clearance provides optimal operation across the specified temperature range of -30°C to 110°C.
