Vibration can generally be expressed in the following three units: mm, mm/s, mm/ S2. Amplitude, vibration velocity (vibration velocity), vibration acceleration. Amplitude is the representation, velocity and acceleration is the degree of rotor excitation force. Mm vibration displace

The vibration value of a rotary bearing at a rated speed of 750r/min shall not exceed 0.12mm, that of a rotary bearing at a rated speed of 1000r/min shall not exceed 0.10mm, that of a rotary bearing at a rated speed of 1500r/min shall not exceed 0.085mm, The vibration value of rotary bearings with
