The Upper Counterweight Assembly is designed to control the vibration angle and flow direction on large vibratory screening systems. Compatible with most 48" and 60" vibratory motors—including standard 2.5HP 213T 1200 RPM models—this assembly ensures efficient material movement across the screen. Its durable, precision-balanced construction makes it essential for fine-tuning screener performance in demanding industrial environments.

Q: What does the upper counterweight control?
A: It adjusts the angle of vibration, which changes how materials spiral, spread, or move across the screen deck.

Q: What motors is this compatible with?
A: It’s compatible with most 2.5HP 213T 1200 RPM vibratory motors used in 48" and 60" screening systems.

Q: Is this sold pre-assembled?
A: CMF does not specify, but it is designed for quick integration with most standard motor shafts.

Q: Do I need to balance it with a lower counterweight?A: Yes. Upper and lower weights should be tuned together for optimal screening performance.
