1311C3 Bearing Product Overview & Core Advantages
The 1311C3 is a double row angular contact ball bearing designed for applications requiring high radial load capacity and operational stability. This precision bearing features an open design and is pre-lubricated for immediate use. Its key advantages include the ability to handle significant combined loads and its construction, which provides high rigidity and reliable performance in demanding industrial environments. The specified C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used.
1311C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1311 | Basic bearing designation indicating bore diameter (55mm), outside diameter (120mm), and width (29mm) |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or interference fits |
1311C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides enhanced stiffness and enables the bearing to withstand substantial radial loads (dynamic: 11,408 lbf, static: 4,050 lbf), making it ideal for applications requiring stable rotational accuracy.
Optimized Material Selection: Constructed from chrome steel for both rings and balls, ensuring durability and wear resistance. The nylon cage contributes to smooth operation and reduced friction at high speeds (limiting speed: 7,500 rpm).
Pre-lubricated & Ready-to-Use: Factory-lubricated for immediate installation and initial operation, reducing maintenance requirements and ensuring optimal performance from startup.
Wide Temperature Range: Operates effectively within a temperature range of -30°C to 110°C, accommodating various industrial environments.
