1213-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1213-K-TVH-C3 is a double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance under combined loads. Featuring a metric tapered bore (1:12 ratio), this precision bearing is designed to accommodate significant radial loads while maintaining dimensional stability. Its open construction allows for optimal lubrication flow, contributing to its robust load carrying capacity and suitability for demanding industrial environments where high reliability is paramount.
1213-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1213 | Standard bearing series designation, indicating bearing dimensions (65mm bore, 120mm OD, 23mm width). |
| K | Indicates a tapered bore with a 1:12 ratio, designed for precise mounting on adapter sleeves or withdrawal sleeves. |
| TVH | Designates the cage material as glass fiber reinforced Nylon (Polyamide 66), offering quiet operation and suitability for high-speed applications. |
| C3 | Specifies a greater radial internal clearance than normal (C0), making it suitable for applications with thermal expansion or where interference fits are used. |
1213-K-TVH-C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to support substantial radial loads (7898 lbf dynamic, 3150 lbf static). This design is inherently stable under combined loading conditions.
Precision Tapered Bore: The K designation signifies a tapered bore, which allows for precise axial positioning and secure mounting on a shaft, eliminating fretting corrosion and ensuring optimal performance.
Optimized High-Speed Performance: The lightweight Nylon cage (TVH) reduces centrifugal forces, lowers friction, and enables a high limiting speed of 7,000 rpm. The open seal design facilitates efficient lubrication for thermal management at high speeds.
Robust Material Construction: Manufactured from Chrome Steel for both rings and balls, the bearing ensures high durability, wear resistance, and a long operational lifespan within a temperature range of -30°C to 110°C.
1213-K-TVH-C3 Bearing Typical Application Areas
The 1213-K-TVH-C3 is ideally suited for a wide range of industrial machinery requiring high precision and reliability. Key application areas include:
- Electric Motors and Generators: Particularly where a tapered bore is used for secure shaft mounting.
- Industrial Gearboxes and Transmissions: Benefitting from its high rigidity and capacity for radial loads.
- Material Handling Equipment: Such as conveyor pulleys, where the C3 clearance accommodates thermal changes.
- Agricultural and Construction Machinery: Utilizing its robust construction and ability to perform in demanding environments.
