1220 C/3 Bearing Product Overview & Core Advantages
The 1220 C/3 is a metric double row angular contact ball bearing engineered for applications demanding high precision and reliability. This precision bearing is designed to accommodate combined loads, simultaneously supporting significant radial loads and axial loads in both directions. Its double-row construction provides a compact and high-rigidity solution, making it ideal for arrangements where space is limited and operational stability is critical. Manufactured from high-grade chrome steel and featuring a CN radial internal clearance, it delivers consistent performance and long service life.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1220 | Basic bearing designation, indicating a metric series double row angular contact ball bearing with a 100mm bore diameter. |
| C | Specifies a 15° contact angle, optimized for supporting high axial loads. |
| 3 | Denotes the CN radial internal clearance (Normal group), which is standard for a wide range of industrial applications. |
1220 C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design significantly increases the bearing's moment stiffness and enables it to handle substantial combined radial and axial loads from both directions, ensuring stable shaft guidance.
- Optimized Material & Construction: The rings and balls are made from high-carbon chrome steel for excellent durability and wear resistance. The stainless steel cage ensures reliable operation at high speeds and in demanding environments.
- Precision Performance: Manufactured with tight dimensional tolerances on the bore diameter, outside diameter, and width, this bearing guarantees precise fit and smooth operation in high-accuracy assemblies.
- Standard Lubrication & Readiness: The bearing is supplied lubricated and ready for installation, facilitating easier maintenance and immediate use.
