1309 C/3 Bearing Product Overview & Core Advantages
The 1309 C/3 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This metric bearing features an open construction and is engineered to accommodate significant combined loads, including radial and bidirectional axial loads. Its compact design and robust construction make it ideal for space-constrained applications demanding high rigidity and stable performance. Pre-lubricated for immediate use, it offers excellent operational readiness across a wide temperature range.
1309 C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1309 | Basic bearing designation indicating size series and bore diameter |
| C | Specific internal design and contact angle optimized for combined loads |
| 3 | Radial internal clearance designation (CN group - normal clearance) |
1309 C/3 Bearing Structural Features & Performance Benefits
Double Row Design: The two rows of balls provide enhanced load capacity and superior rigidity compared to single row bearings, making it suitable for applications with significant radial and axial forces.
Optimized Internal Geometry: Precision-engineered raceways and contact angles ensure efficient load distribution and smooth operation under combined loading conditions.
Nylon Cage Construction: The lightweight nylon cage contributes to reduced friction and enables higher operating speeds while providing excellent guidance for the balls.
Precision Tolerances: Tight dimensional tolerances on bore diameter, outside diameter, and width ensure consistent performance and easy installation in precision applications.
Wide Temperature Range: Chrome steel construction and appropriate lubrication allow operation from -30°C to 110°C, suitable for various industrial environments.
