1218-TVH-C5 Bearing Product Overview & Core Advantages
The 1218-TVH-C5 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precision. This precision bearing excels at simultaneously supporting substantial combined loads, including radial forces and bidirectional axial loads, within a compact bearing dimension profile. Its open design, pre-lubricated state, and optimized internal geometry make it an ideal solution for high-reliability machinery where performance consistency is critical.
1218-TVH-C5 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 1218 | Standard bore diameter (90 mm) and series designation. | Defines the core bearing size and cross-section. |
| TVH | Polyamide (Nylon) cage, pressed window type. | Enables quiet operation and is suitable for high-speed applications. |
| C5 | Radial internal clearance group, greater than normal (CN). | Accommodates thermal expansion in applications with high operating temperatures or heavy loads, ensuring optimal performance. |
1218-TVH-C5 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and optimized contact angles provide exceptional high rigidity, enabling the bearing to handle significant combined loads (radial and axial) without sacrificing performance.
High-Speed Performance: The lightweight Nylon cage (TVH) reduces centrifugal forces, minimizes friction, and contributes to a high limiting speed of 5,300 rpm, making it a capable high-speed bearing.
Optimized Internal Geometry: The specified C5 radial internal clearance is engineered for applications prone to thermal expansion, preventing preload and ensuring smooth operation under varying thermal conditions.
Ready-to-Install: The bearing is supplied lubricated and open, allowing for the application of specific lubricants tailored to the operational environment, offering flexibility for specialized requirements.
