Product Overview and Core Advantages
The 1217/C3 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 with a C3 radial internal clearance, making it ideal for scenarios involving thermal expansion or where interference fits are used. Its double row construction provides high rigidity and excellent running accuracy, ensuring reliable performance in demanding industrial environments. The bearing comes pre-lubricated and is manufactured from high-grade chrome steel for extended service life.
1217/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1217 | Standard bearing designation indicating bearing dimensions: 85mm bore, 150mm OD, 28mm width |
| C3 | Specifies greater radial internal clearance than normal (C0), suitable for applications with thermal expansion or shaft interference fits |
Structural Features and Performance Benefits
- High Rigidity and Load Capacity: The double row design provides superior radial stiffness and can accommodate significant combined loads, making it suitable for applications with heavy radial forces and moderate axial loads in both directions.
- Optimized Internal Clearance: The C3 clearance accommodates thermal expansion during operation, preventing premature failure due to excessive preload in high-temperature applications.
- Premium Material Construction: Manufactured from chrome steel rings and balls with a stainless steel cage, ensuring durability, corrosion resistance, and consistent performance under demanding conditions.
- Pre-lubricated Design: Factory-applied lubrication provides immediate operational readiness and initial protection, supporting the bearing's limiting speed of 5,600 rpm.
1217/C3 Bearing Typical Application Areas
- Industrial gearboxes and transmission systems
- Material handling equipment and conveyor systems
- Electric motors and industrial fans
- Agricultural machinery and construction equipment
- Pump and compressor applications
- General industrial machinery requiring high radial load capacity
