Clear information on the status of travelling machine parts is critical in many fields of engineering. Control systems depend on this kind of input to ensure reliable control of movements.
The SKF sensorised bearing unit – which integrates sensor, impulse ring and bearing – is a compact solution to record movement data for machine control. Data include number of revolutions, speed, direction of rotation and relative position, as well as acceleration or deceleration.

Originally developed for automotive applications such as anti-lock braking systems, sensorised bearing units have since been adapted to many other fields of engineering. Millions of these intelligent SKF bearings are now in operation worldwide, providing high-quality signal generation and transmission.
