1309-K-TVH-C3 Bearing Product Overview & Core Advantages
The 1309-K-TVH-C3 is a double row angular contact ball bearing designed for applications requiring exceptional rigidity and the capacity to handle combined loads. Its metric design features a tapered bore for secure shaft mounting, enabling it to support significant radial loads while accommodating axial loads in both directions. Constructed with precision components including a nylon cage and chrome steel rings and balls, this bearing is engineered for high-speed operation and reliable performance in demanding industrial environments. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used.
1309-K-TVH-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Significance |
|---|---|---|
| K | Tapered Bore (1:12) | Facilitates precise axial positioning and secure interference fit on the shaft, enhancing bearing rigidity. |
| TVH | Nylon Cage (Polyamide), Snap-Type | Contributes to high-speed performance, reduced friction, and quieter operation. It is lightweight and offers excellent guidance for the balls. |
| C3 | Radial Internal Clearance greater than Normal | Accommodates thermal expansion from high-speed operation or tight interference fits, preventing premature failure due to excessive preload. |
1309-K-TVH-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity compared to single row bearings, making it ideal for applications with moment loads or shaft misalignment. It is rated for a radial dynamic load of 8775 lbf and a radial static load of 3015 lbf, effectively handling combined loads.
- Optimized High-Speed Performance: The combination of the lightweight nylon cage (TVH) and the open design allows for efficient lubrication and heat dissipation, supporting a limiting speed of 8,500 rpm.
- Precision Tapered Bore: The K-designation tapered bore ensures a tight and secure fit on a tapered shaft adapter, minimizing inner ring creep and maximizing power transmission efficiency.
- Robust Material Construction: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers excellent durability, wear resistance, and a long operational life under demanding conditions.
