High precision ball bearings
Integrated bearings
The super duplex bearings with an integrated hard preload improve the overall performance of a rotating system. Rotation precision is obtained thanks to its design with a double-groove outer ring, which keeps geometrical defects to a minimum and reduces torque.
There is a standard ADR series known as KADV. These bearings are available in back-to-back configuration with centred inner rings allowing a very high load-bearing capacity and increasing angular stiffness.
Its hard preload applied with screws makes it possible to guarantee the repetitiveness of this parameter from one bearing to another and provides complete control over the desired stiffness performance.
The preload value will be determined by the loads placed on the bearing.
