1311-TVH Bearing Product Overview & Core Advantages
The 1311-TVH is a double row angular contact ball bearing designed for demanding applications requiring high rigidity and reliable performance under combined loads. This metric bearing features an open design without integral seals, allowing for optimal lubrication management and suitability for high-speed operation. Its double row construction provides exceptional stiffness and can accommodate significant radial loads along with axial loads in both directions. Manufactured from high-grade chrome steel and featuring a lightweight nylon cage, it is engineered for precision, durability, and long service life in industrial environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1311 | Standard bearing designation indicating the bearing size with a 55 mm bore and 120 mm outside diameter. |

1311-TVH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust construction provide superior stiffness, enabling the bearing to handle high radial dynamic load ratings of 11408 lbf and combined loads effectively.
- Optimized for Speed: The lightweight and resilient nylon cage ensures smooth operation and stability at high rotational speeds, contributing to the bearing's limiting speed of 7,500 rpm.
- Precision & Durability: Manufactured from chrome steel for both rings and balls, the bearing offers high wear resistance and dimensional stability. The standard CN radial internal clearance is suitable for a wide range of common operating conditions.
- Flexible Lubrication: The open seal type allows for the use of various lubricants, enabling customization based on specific application requirements for temperature and speed.
