1214-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1214-K-TVH-C3 is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and precise operation. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing delivers exceptional rigidity and stability. Its open design allows for customized lubrication schemes, while the C3 radial internal clearance makes it suitable for applications with thermal expansion or heavy interference fits. Manufactured from chrome steel with a nylon cage, it offers reliable performance across a temperature range of -30° to 110°C, making it an ideal choice for demanding industrial environments.
1214-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 1214-K-TVH-C3 provides detailed technical specifications through its suffix codes:
- 1214: Basic designation indicating bore diameter (70 mm), outside diameter (125 mm), and width (24 mm)
- K: Denotes tapered bore with 1:12 taper ratio for precise shaft fitting
- TVH: Specifies the cage material - glass fiber reinforced nylon (polyamide) providing excellent strength and wear resistance
- C3: Indicates greater radial internal clearance than normal, suitable for applications with thermal gradients or heavy interference fits
1214-K-TVH-C3 Bearing Structural Features & Performance Benefits
The double row design of the 1214-K-TVH-C3 provides superior load carrying capacity and high rigidity, enabling it to handle significant radial loads while maintaining dimensional stability. The 1:12 tapered bore ensures secure mounting on tapered shaft seats, preventing slippage under heavy loads. The nylon cage (TVH) contributes to smooth operation at limiting speeds up to 7,000 rpm, while offering reduced friction and quiet running. The C3 clearance accommodates thermal expansion in high-speed applications or interference fits, preventing premature failure. With a dynamic load rating of 8,055 lbf and static load rating of 3,285 lbf, this bearing delivers reliable performance in demanding conditions.
1214-K-TVH-C3 Bearing Typical Application Areas
The 1214-K-TVH-C3 finds extensive use in industrial applications requiring high radial load capacity and precise operation, including:
- Industrial gearboxes and power transmission systems
- Material handling equipment including conveyor systems
- Agricultural machinery and implements
- Electric motors and industrial fans
- Pump systems requiring reliable bearing performance
- Construction equipment with demanding load requirements
