Sensorized tapered bearing units

Sensorised CTBU

Compact, ready-to-mount and easy-to-install, SKF sensorized tapered bearing units form part of the braking system. They optimize frictional engagement of the driving wheels on starting-up, detecting the direction of rotation and bearing temperature.

These units offer the ability to detect:

  • rotational speed for the wheel slip/slide protection
  • (WSP or WSSP) and traction control unit (TCU)
  • bearing temperature signal for the on board monitoring system
  • direction of movement
  • positioning for the European Train Control System (ETCS) and the Italian SCMT (Sistema controllo movimentazione treno) automatic train control systems
  • vertical and/or lateral acceleration
