1220C3 Bearing Product Overview & Core Advantages
The 1220C3 is a metric double row angular contact ball bearing engineered for demanding industrial applications requiring high precision and reliability. This bearing features an open design with high radial load capacity and is capable of accommodating combined loads. Manufactured from chrome steel with a stainless steel cage, it offers excellent durability and corrosion resistance. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring stable performance under varying operational conditions.
Model Code Detailed Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1220 | Basic bearing designation indicating bore diameter (100mm) and standard dimensions |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or interference fits |
1220C3 Bearing Structural Features & Performance Benefits
Double Row Design: The double row ball bearing construction provides enhanced rigidity and load capacity compared to single row bearings, making it ideal for applications requiring high stability.
Premium Materials: Constructed with chrome steel rings and balls combined with a stainless steel cage, this bearing delivers superior strength, wear resistance, and extended service life in challenging environments.
Optimized Performance: With a radial dynamic load rating of 15,502 lbf and limiting speed of 4,800 rpm, this bearing maintains reliable operation under significant loads and moderate speeds. The C3 clearance ensures proper functioning despite thermal variations.
Precision Engineering: Featuring tight dimensional tolerances on bore diameter (-0.02mm to 0) and outside diameter (-0.025mm to 0), this bearing ensures precise fitment and consistent performance in precision applications.
