1309-K-TVH Bearing Product Overview & Core Advantages
The 1309-K-TVH is a double row angular contact ball bearing designed for applications demanding high rigidity and the ability to handle combined loads. Its metric design features a tapered bore (1:12 ratio) for precise shaft mounting, contributing to exceptional running accuracy. This precision bearing is engineered to support significant radial loads while accommodating axial loads in both directions, making it an ideal, compact solution for high-reliability industrial environments. The use of a Nylon cage facilitates smooth operation at high speeds.
1309-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 positioning and a tight interference fit on the shaft when mounted with an adapter sleeve or withdrawal sleeve. |
| TVH | Denotes a Nylon (Polyamide) cage, glass fiber reinforced. This cage design is lightweight, promotes excellent high-speed performance, and offers low friction and quiet operation. |
1309-K-TVH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior radial and axial stiffness, enabling the bearing to effectively manage combined loads (simultaneous radial and axial forces) from both directions.
- High-Speed Performance: The lightweight and robust Nylon cage (TVH) minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 8,500 rpm.
- Precision Tapered Bore: The K suffix tapered bore ensures a secure and precise fit on the shaft, minimizing inner ring creep and enhancing overall system stability and accuracy.
- Optimized Internal Geometry: The specified CN group radial internal clearance is a standard, normal clearance suitable for a wide range of common operating conditions.
1309-K-TVH Bearing Typical Application Areas
This bearing is specified for use in demanding machinery where high rigidity and combined load capacity are critical. Key applications include:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Vibrating screens and other equipment requiring a secure tapered bore mount.
