1204-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1204-K-TVH-C3 is a double row angular contact ball bearing designed for applications demanding high rigidity and reliable performance under combined loads. Its metric design features a tapered bore (1:12) for secure shaft mounting. This precision bearing is pre-lubricated and features a C3 radial internal clearance, making it suitable for applications with thermal expansion or where a slightly looser fit is required. The open construction allows for high-speed operation, while the nylon cage contributes to smooth, quiet running and is ideal for a wide operating temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1204 | Basic bearing series and size code. |
| K | Indicates a tapered bore with a 1:12 ratio. |
| TVH | Designates a glass fiber reinforced nylon cage (PA66-GF25). |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. |
1204-K-TVH-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement provides superior high rigidity and enables the bearing to accommodate significant combined loads (radial and axial).
- High-Speed Performance: The lightweight nylon cage minimizes centrifugal forces, reduces friction, and allows for a limiting speed of 20,000 rpm, classifying it as a high-speed bearing.
- Tapered Bore for Secure Fit: The K-designation tapered bore allows for precise axial positioning and a tight, slip-free fit on a tapered shaft adapter, crucial for high-speed and high-vibration environments.
- Optimized Internal Clearance: The C3 clearance is engineered for applications where thermal expansion of the shaft and housing must be accommodated without inducing excessive preload, ensuring consistent performance.
1204-K-TVH-C3 Bearing Typical Application Areas
This bearing is engineered for demanding industrial applications, including:
- Electric Motor Spindles
