1312-K-TVH Bearing Product Overview & Core Advantages
The 1312-K-TVH is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing features a tapered bore (1:12) and is pre-lubricated for immediate use. Its core advantage lies in its ability to support significant combined loads—handling both high radial loads and axial loads in both directions simultaneously. The double row design provides superior high rigidity and stability, making it an ideal choice for applications requiring precise shaft positioning and reliable operation under challenging conditions.
1312-K-TVH Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| K | Indicates a tapered bore with a 1:12 ratio. This allows for precise axial clearance adjustment and secure mounting on adapter sleeves or withdrawal sleeves. |
| TVH | Signifies a Nylon (Polyamide) cage and that the bearing is lubricated. The cage design contributes to lower friction, reduced weight, and excellent performance at high speeds. |
1312-K-TVH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide high radial and axial stiffness, enabling the bearing to handle substantial combined loads effectively.
- Precision Tapered Bore: The K-suffix tapered bore (1:12) facilitates easy installation and allows for fine-tuning of the internal clearance, ensuring optimal preload and operational precision.
- High-Speed Capability: The lightweight Nylon cage (TVH) minimizes centrifugal forces, reduces friction, and allows for a higher limiting speed of 6,300 rpm, making it suitable for high-speed applications.
- Ready-to-Use & Low Maintenance: The bearing comes pre-lubricated, enabling immediate installation and reducing initial setup time. The open design, while requiring a sealed environment, allows for re-lubrication in service for extended life.
1312-K-TVH Bearing Typical Application Areas
This bearing is engineered for high-performance machinery where rigidity and speed are critical. Key applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Pump Spindles and Compressors
- Material Handling Equipment
- Agricultural Machinery
