Shock Absorber Stepper Motor Vibration Damper for 3D Printer Nema17 Stepper Motor (stepper damper)
Features:
Specifications:
Effective to reduce shock.
Antivibration dampers for mostly applied stepper motors are available.
Energy-absorbing rubber mounts with a metal mounting face.
Stepper motors are affected by resonance.
Resonance is caused by parts vibrating in concert with each other, which can be lessened by fitting a stepper motor antivibration damper.Specifications:
