Product Overview:
The 3207 Angular Contact Ball Bearing is precisely engineered to support combined radial and axial (thrust) loads simultaneously. Its unique raceway design, featuring an offset between the inner and outer rings, creates an optimized contact angle that effectively manages axial forces in one direction. This design ensures excellent shaft alignment, rigidity, and rotational precision, making it ideal for demanding industrial applications.
High-Speed Stability
Optimized internal geometry and precision-ground raceways enable low noise, minimal vibration, and reduced heat generation at high rotational speeds.
Superior Rigidity
Provides exceptional stability and minimal deflection under heavy loads, critical for maintaining accuracy in machine tools, gearboxes, and high-precision assemblies.
Long Service Life
Advanced materials and surface finishes enhance wear resistance and fatigue strength, reducing maintenance costs and downtime.
Flexible Configurations
Can be mounted in back-to-back, face-to-face, or tandem pairs to handle axial loads in both directions or to increase overall load capacity.
