Are you struggling with product development?
Let our balancing technology and evaluation technology for rotating machinery vibration help you!

Balancing

Most of the vibration problems in rotating parts are caused by unbalance. We offer proposals, experiments, and measurements for balancing of customers’ newly developed products. We also design and manufacture attachments for new workpieces, such as in the case of rotors with complex shapes.

Rotating Machinery Vibration

If you are experiencing vibration problems with your rotating machinery, we can help you. Please feel free to contact us with any questions you may have, even if they are trivial matters. Please feel free to contact us.

Balancing

(1) Horizontal balancing machines

This type of machines is capable of measuring ultra-small to medium-sized rotors. Not only rigid rotors, but also elastic rotors and magnetized rotors can be balanced. If the rotor shape is complicated, we can design and manufacture a special attachment.

* For NRS and NRI types, it is usually necessary to design and manufacture a special attachment to fit the rotor.

(2) Vertical balancing machine

The vertical balancing machine can also measure the unbalance of a rotor without a shaft. Normally, it is necessary to design and manufacture a special attachment to fit the rotor.

(3) Balancing of elastic rotors

Balancing can be performed at the specified speed as long as it is within the speed range applicable to the balancing machine. We can also provide field balancing service for actual rotating machineries. The efficiency of balancing of an elastic rotor depends on the number of critical speeds considered and the position and number of balancing planes, but we can provide best solution for balancing using optimal computation.
