Mulcher vibration can be caused by a wide range of sources. Most often, it is simply a mass imbalance of the rotor assembly. Even a statically balanced rotor can vibrate and needs to be dynamically balanced. It is virtually impossible to balance every rotating component and then mount each one perfectly. Even the simple act of remounting a rotor can cause a mass imbalance due to slight alignment changes. The Fecon Mobile Balancers graphically guide you through the dynamic balancing process so you can balance your rotor quickly and easily with the minimum number of runups.

 cost-effective solutions to the damaging vibration caused by rotor imbalance

FMB-100 Dynamic Balancer


The Fecon FMB-100 is an extremely cost-effective solution to the damaging vibration caused by rotor imbalance. The FMB-100 mobile balancer tells you how out-of-balance the rotor is (magnitude), and where adjustments are needed (phase/angle). Once these adjustments are made, you will notice an amazing difference in performance and efficiency.

FMB-200 Dynamic Balancer


The Fecon FMB-200 is a state-of-the-art dynamic balancer with full spectral vibration analysis. Not only does it walk you through the balancing process indicating where to add weight and how much, but it also analyzes all frequencies to help troubleshoot vibrations that are not from rotor imbalance. It can tell the difference between a rotor imbalance, a failed bearing, or bent shaft, as well as other
sources of damaging vibration.
