TAUh30-50f Automobile Hub Bearing Torque Rigidity and Preload Testing Machine

Application: the moment rigidity measurement of hub bearing in the inner diameter 30-50mm range are mainly used. Resonance method is used to test the bearing inner and outer ring resonant frequency and damping coefficient, and analysis the bearing pre-load size.
