1216-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1216-K-TVH-C3 is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and precise operation. Featuring a 1:12 tapered bore for secure shaft mounting, this metric bearing excels at handling significant combined loads (radial and axial) simultaneously. Its open design, pre-lubricated for immediate use, and C3 radial internal clearance make it an ideal precision bearing for high-performance machinery where reliability and dimensional accuracy are paramount.
1216-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 1216-K-TVH-C3 provides a complete technical description:
- 1216: Basic designation indicating a double row angular contact ball bearing with a 80mm bore and 140mm outside diameter.
- K: Denotes a tapered bore with a 1:12 ratio, facilitating precise axial positioning and a tight interference fit on the shaft.
- TVH: Specifies the cage material. TVH indicates a window-type, glass fiber reinforced nylon cage, which offers low weight, low friction, and is suitable for high-speed operation.
- C3: Indicates a greater than normal radial internal clearance. This is selected for applications where thermal expansion of the shaft and housing is expected, ensuring optimal performance under operational temperatures.
1216-K-TVH-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior rigidity and enables the bearing to support heavy radial loads and substantial axial loads in both directions, making it exceptionally robust for combined load scenarios.
- Optimized for Performance: The nylon (TVH) cage ensures smooth operation at high speeds (with a limiting speed of 6000 rpm), reducing friction and wear. The open seal type allows for optimal lubrication flow and heat dissipation.
- Precision Tapered Bore: The 1:12 tapered bore (K-designation) ensures a secure, concentric fit on the shaft, minimizing slippage and vibration for enhanced operational precision.
- Pre-lubricated & Ready for Use: Supplied with lubricant, the bearing is immediately ready for installation, reducing setup time. The C3 clearance accommodates thermal expansion, preventing preload and ensuring longevity in variable temperature environments (-30°C to 110°C).
1216-K-TVH-C3 Bearing Typical Application Areas
This bearing is engineered for high-performance industrial systems, including:
- Machine Tool Spindles
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Vibrating Screens and Material Handling Equipment
- Agricultural and Construction Machinery
