The Lower Counterweight Assembly is designed to optimize motion control in 30" vibratory screening systems. Compatible with popular models like the ItalVibras 2/3HP and Martin Engineering F3-30 1/2HP motors, this precision-engineered assembly provides the necessary balance to drive consistent elliptical or circular vibration. Built from durable materials, it installs directly on the motor shaft for fast integration and long-lasting performance.

Q: Which motors are compatible with this counterweight?
A: It fits most 30" vibratory motors, including ItalVibras 2/3HP and Martin Engineering F3-30 1/2HP models.

Q: What is the function of a lower counterweight?
A: It provides rotational force that helps generate elliptical or circular motion in the screener system, balancing the motor and optimizing performance.

Q: Is this part pre-balanced?
A: The CMF does not confirm pre-balancing. For best results, ensure proper installation and consult the motor manufacturer for adjustment guidance.

Q: How do I install this assembly?
A: It mounts directly to the lower shaft of the vibratory motor. Always follow the motor's installation instructions to maintain balance.
