Product Overview: The 7012 Angular Contact Ball Bearing
The 7012 bearing is a high-precision, single-row angular contact ball bearing designed for high-speed applications that require support for combined (axial and radial) loads. With principal dimensions of 60mm Bore Diameter, 95mm Outer Diameter, and 18mm Thickness, this bearing is a crucial component in machinery where rotational accuracy and rigidity are paramount. As part of our 7000 Series, the 7012 features raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. This design allows it to accommodate axial loads in one direction, making it ideal for specific mounting arrangements.
As a specialist supplier of industrial mechanical parts, we provide top-quality bearings that meet stringent industry standards. The 7012 must typically be mounted in pairs (back-to-back, face-to-face, or tandem) to handle axial loads in both directions and create a rigid bearing system. Explore our comprehensive range of Angular Contact Ball Bearings to find the optimal solution for your high-performance applications.
