1215C3 Bearing Product Overview & Core Advantages
The 1215C3 is a double row angular contact ball bearing designed for applications requiring high load capacity and operational stability. This precision bearing excels at simultaneously handling significant radial loads and moderate axial loads in both directions. Its compact design, featuring a 25 mm width, makes it ideal for space-constrained, high-reliability machinery. The bearing is pre-lubricated and features a generous C3 radial internal clearance, making it robust against thermal expansion and suitable for a wide operating temperature range from -30°C to 110°C.
1215C3 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Advantage |
|---|---|---|
| 1215 | Standard designation for bore diameter (75 mm), outside diameter (130 mm), and width (25 mm). | Defines the bearing dimensions for precise interchangeability and fit. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Provides operational stability in applications with expected thermal expansion, such as in electric motors or gearboxes. |
1215C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior high rigidity and enables the bearing to support substantial combined loads, with a dynamic load rating of 8775 lbf and a static load rating of 3510 lbf.
- Optimized for Performance: The stainless steel cage ensures durability and stable operation at the limiting speed of 6,700 rpm. The open seal type allows for versatile re-lubrication strategies in demanding environments.
- Robust Material Construction: Manufactured from chrome steel for both rings and balls, the bearing offers excellent wear resistance and a long operational lifespan.
- Pre-Lubricated & Ready for Use: Comes pre-lubricated from the factory, facilitating easy installation and immediate operation.
