1219/C3 Bearing Product Overview & Core Advantages
The 1219/C3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high load capacity and reliable performance. This precision bearing features an open design and is pre-lubricated, enabling it to accommodate significant combined loads (radial and axial) simultaneously. Its compact bearing dimensions (95mm bore, 170mm OD, 32mm width) and robust construction make it an ideal choice for applications where high rigidity and stability are critical. The specified C3 radial internal clearance ensures optimal performance under operational thermal expansion.
1219/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 1219 | Basic bearing designation indicating the double row angular contact ball bearing series with specific dimensions. | Defines the fundamental size and type of the bearing. |
| /C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Ensures optimal performance in applications with expected thermal expansion, such as in electric motors or gearboxes. |
1219/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior high rigidity and enables the bearing to support substantial combined loads, including heavy radial loads and bidirectional axial loads, in a single, compact unit.
- Optimized for Performance: The stainless steel cage ensures durability and stable operation, contributing to the bearing's reliability. The open seal type allows for efficient re-lubrication in service, extending operational life.
- Pre-Lubricated & Ready for Use: Supplied as lubricated, the bearing is immediately ready for installation, reducing setup time and ensuring initial operational smoothness.
- Material Integrity: Manufactured from chrome steel for both rings and balls, the bearing offers excellent wear resistance and a long service life under demanding conditions.
1219/C3 Bearing Typical Application Areas
The 1219/C3 bearing is engineered for robust performance in a wide range of industrial machinery, including:
- Industrial Gearboxes and Transmissions
- Electric Motors and Generators
- Material Handling Equipment (conveyors, pulleys)
- General Industrial Machinery requiring high load capacity and reliability
