Manufacturer profiles associated with Eccentric weights.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Eccentric weights create vibration through rotational imbalance. As the offset mass rotates, it generates centrifugal forces that change direction, transmitting oscillatory motion to the machine structure through bearings and shafts.
High-density materials like ductile cast iron and forged steel provide optimal mass-to-volume ratios. Tungsten alloys offer maximum density for space-constrained applications where high centrifugal force is needed.
Vibration amplitude is controlled by adjusting the eccentric mass amount, the distance from rotational center (eccentricity), or the rotational speed. Some designs allow adjustable eccentricity for variable amplitude.
