1218-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1218-K-TVH-C3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precise operation. This metric bearing features a 1:12 tapered bore for secure shaft mounting and is optimized to handle significant combined loads, including radial and axial forces. Its double row construction provides superior stability and load capacity in a compact bearing size of 90mm bore and 160mm outside diameter. Pre-lubricated and featuring a C3 radial internal clearance, it is engineered for reliable performance in industrial environments.
1218-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1218-K | Indicates the basic bearing designation with a 1:12 tapered bore (K-suffix). |
| TVH | Signifies a Nylon (Polyamide) cage, which contributes to lower friction, quieter operation, and is suitable for high-speed applications. |
| C3 | Denotes a greater radial internal clearance than the Normal (CN) group. This is beneficial for applications with thermal expansion or where interference fits are used. |
1218-K-TVH-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides exceptional stiffness, enabling it to support heavy combined loads and moment loads effectively.
- Optimized for Speed: The lightweight Nylon cage (TVH) reduces centrifugal forces, allowing for a higher limiting speed and smoother operation.
- Tapered Bore Mounting: The 1:12 tapered bore ensures a precise and secure fit on adapter sleeves or tapered shafts, minimizing slippage and vibration.
- Robust Material Construction: Manufactured from Chrome Steel for both rings and balls, ensuring high durability and long service life under demanding conditions.
- Pre-Lubricated for Immediate Use: The bearing comes lubricated from the factory, facilitating quick installation and initial operation.
1218-K-TVH-C3 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring robust performance and high precision, including:
- Industrial Gearboxes and Transmissions
- Vibrating Screens and Conveyors
- Agricultural Machinery
- Material Handling Equipment
- Pump and Compressor Systems
