HBU3 – Generation 3 hub bearings
Generation 3 hub bearings have a flange for wheel and brake attachment and a second flange for fixing the unit to the suspension. They are typically used for both driven and non-driven wheel applications. For driven wheel applications, torque is transmitted to the inner ring via an included spline. Units for vehicles with ABS, Traction Control, and/or Stability Control systems include a wheel speed sensor. The sensor can be located between the bearing rows, on the outboard flange or on the inboard flange.
