1205TNC3 Bearing Product Overview & Core Advantages
The 1205TNC3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. This precision bearing features an open design and is pre-lubricated for immediate use. Its compact construction, with a 25 mm bore, 52 mm outside diameter, and 15 mm width, makes it an ideal solution for space-constrained assemblies. The bearing is engineered to accommodate significant radial loads while also handling axial loads in both directions, making it a versatile and robust component for high-reliability scenarios.
1205TNC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1205 | Standard bearing designation indicating a 25 mm bore diameter and a light series. |
| T | Signifies a Nylon cage, which contributes to quiet operation, low friction, and is suitable for high-speed applications. |
| N | Indicates a snap ring groove on the outer ring for secure and easy axial location within a housing. |
| C3 | Specifies a greater than normal radial internal clearance. This is beneficial for applications with high thermal gradients or where interference fits are used, preventing preload and ensuring smooth operation. |
1205TNC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and contact angle design provide superior stiffness, enabling the bearing to effectively support substantial radial loads and bidirectional axial loads simultaneously.
High-Speed Performance: The lightweight Nylon cage (T) ensures excellent guidance of the balls with minimal centrifugal force, contributing to a high limiting speed of 18,000 rpm. This makes it a capable high-speed bearing.
Optimized Internal Clearance: The C3 clearance offers operational flexibility in applications prone to thermal expansion, preventing binding and reducing friction-induced heat.
Pre-lubricated & Ready-to-Use: Factory-applied lubrication ensures immediate operation upon installation, reducing assembly time and providing initial protection.
1205TNC3 Bearing Typical Application Areas
The 1205TNC3 is widely used in various industrial machinery and precision equipment, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Systems
- Agricultural Machinery
- General machinery requiring robust support for combined loads
