Dynamic Balancing Services

balance-2

We can balance at our facility or yours.

Shop balancing at our facility is performed using a Schenck Trebel ‘Hard bearing” balancer. A hard bearing machine balances well below the resonant frequency of the balancers pedestals which are rigid, as opposed to a soft bearing machine that balances at a speed somewhat higher than the resonant frequency of the machine pedestals which are free to move. Heavy parts that have high initial unbalance can be balanced more efficiently and safely because a hard bearing machine can balance at very low speeds.

Advantages of hard bearing machines;

  • No calibration or trial weights are required as unbalance is measured in the first spin.
  • Unbalance indication is independent of balancing speed; therefore ever the lightest or heaviest rigid rotors within the machines capacity can be balanced to low levels regardless of actual service speed.
  • Heavy parts that have high initial unbalance can be balanced more efficiently and safely because a hard bearing machine can balance at very low speeds.
  • As the pedestals are rigid solid castings with few moving parts they are much narrower than soft bearing styles allowing short journals and minimally spaced assembly components.
  • Robust negative hold down brackets allow heavy overhung (cantilevered) rotors, even those with short shafts.For rotors that cannot be removed from service we can also balance on site with our Emerson Process (CSI) 2115 or 2120 portable balancing systems. We can balance a wide variety of shafts, rotors, discs, and
