Features HIGH QUALITY These energy absorbing rubber bases have a metal mounting surface. The product contains 5 dampers made of high-quality metal and rubber, which are not easily deformed and damaged and are durable. Operating principle: stepper motors are subject to resonances that are caused to oscillate by coordinated components. The resonance can be reduced by installing vibration dampers for stepper motors. Excellent Performance These dampers can effectively reduce vibration. These dampers are used to reduce noise and vibration from stepper motors, reduce noise and resonance from CNC and 3D printers, and increase printing speed. Applicable Objects The engine shock absorber is suitable for CNC 3D printer stepper motors. It is an excellent vibration damper suitable for quiet stepper motors. It meets strict quality control standards and is reliable in use. Quality Assurance The vibration damper is manufactured under strict quality control and standard requirements, and has a high safety factor, so it can be used with confidence.
