1306L1C3 Bearing Product Overview & Core Advantages
The 1306L1C3 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This precision bearing excels at simultaneously handling combined loads—both radial and bidirectional axial forces—thanks to its optimized contact angle and double row design. Its compact bearing dimensions (30mm bore, 72mm OD, 19mm width) make it ideal for space-constrained installations while providing exceptional high rigidity support. Manufactured with chrome steel rings and balls with a brass cage, it delivers consistent performance under demanding conditions.
1306L1C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Implication |
|---|---|---|
| 1306 | Standard bearing size designation | Defines core dimensions: 30mm bore, 72mm OD, 19mm width |
| L1 | Light preload specification | Provides optimized internal clearance for precision applications |
| C3 | Radial internal clearance group | Greater than normal clearance for thermal expansion in operating conditions |
1306L1C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior stiffness compared to single row bearings, enabling stable operation under combined loads with radial dynamic load rating of 5062 lbf and static rating of 1530 lbf.
Precision Engineering: Manufactured with chrome steel rings and balls combined with a brass cage, this bearing maintains dimensional stability and smooth operation. The C3 radial clearance accommodates thermal expansion during high-speed operation.
High-Speed Capability: With a limiting speed of 13,000 rpm, this bearing is optimized for high-speed applications. The brass cage ensures reliable performance at elevated rotational speeds.
Maintenance Features: The open design allows for customized lubrication strategies, while the pre-lubricated configuration provides immediate operational readiness.
