The moment rigid testing platform is mainly used for testing the moment rigid of automobile hub. It adopts pneumatically loading and manual control of load; it applies to computer to sample automatically,Website:://.zys-bearing.com, calculate the angle, and store the data.  TAUh30-50f Automobile Hub Bearing Torque Rigidity and Preload Testing MachinePurpose: 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.　　　　　　　Test type:Hub bearingTest inner diameter range:φ30～φ50mmTest number:1Maximum test load:Radial 15kN，axial 10kNMaximum relative inclination:2°Exciting:Frequency 3000Hz, exciting force 15kg, amplitude ±5mmTest methods:Automatic computer control,monitoring and recording.Test parameters:Stiffness, angle, load, Resonant frequency, damping coefficient, etc.
