1215K C3 Bearing Product Overview & Core Advantages
The 1215K C3 is a double row angular contact ball bearing designed for demanding industrial applications requiring high rigidity and reliable performance under combined loads. Featuring a tapered bore (1:12) and open construction, this precision bearing excels in applications where radial and axial loads are present simultaneously. Its optimized internal geometry and C3 radial internal clearance make it particularly suitable for installations with interference fits and elevated operating temperatures, ensuring stable operation and extended service life.

1215K C3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row ball bearing construction provides superior stiffness compared to single row designs, effectively resisting deflection under heavy combined loads and ensuring precise shaft positioning.
Enhanced Load Capacity: Engineered to handle significant radial loads while accommodating axial loads in both directions, making it ideal for applications with complex loading conditions.
Optimized Performance: The nylon cage contributes to smooth operation at the limiting speed of 6,700 rpm, while the tapered bore design ensures secure mounting and proper load distribution.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances, this bearing delivers consistent performance and reliability in precision machinery applications.
