Angular Contact Bearings
They are used on shafts that encounter axial forces or combined loads (both axial and radial forces). Examples are centrifugal and helical rotor pump shafts and helical and worm gear shafts in gearboxes. Their design only permits axial forces in one direction. For alternating axial loads they must be installed as a bearing set to accommodated the forces from both directions. When set back to back, and less so when set face to face, they act to stiffen the shaft and handle larger bending moments such as overhung components or high midpoint shaft loading.

Agitator Shafts Thrust Bearing
Vertical tank agitator bearings are required to take both radial and thrust loads.
To protect the gearbox it is common practice to install intermediate bearings on the shaft. If these bearings are exposed to the process vapors then special care is needed to protect them from contamination and ensure adequate lubrication.
