Balance Checker

Safe and high-precision measurement of static balance


Measures the static balance (static unbalance) with high precision of a workpiece in a non-rotating state.
Uses the original three-point measuring system by center-axial-alignment mechanism. You only need to input an outside diameter of a workpiece and set the workpiece on the table to detect its unbalance weight and position in a non-rotating state.

OKK's Balance Checker performs high-precision balance measurement and outstanding repeat accuracy among other devices in the market.
Easy to make the changeover or operate for high-precision static balancing.

Static balance

static balancing is a way to detect the unbalance weight distribution of a workpiece in a non-rotating state.

How is it different from dynamic balance?

Dynamic balancing is a way to detect the unbalance weight and position by vibration while the measuring object rotates.

Dynamic balancing would carry big risks due to its measuring method based on rotation of a workpiece. It would cost a great deal for safety measures or it could cause to harm a person, especially if it is a large workpiece, blade, or screw.


Outstanding accuracy of static balance detection

Our original three-point measuring system by center-axial-alignment mechanism brings outstanding detection accuracy among other devices in the market.

What is the three-point measuring system by center-axial-alignment mechanism?
Makes the center-axial-alignment with center attachment, detects the weight distribution with the three measuring devices under the measuring plate, and calculates the unbalance position and weight.

Easy operation

Input workpiece information and press Measurement button.
Does not require technical experience.
Easy to perform static balancing with high precision.

Easy changeover

You can quickly make the changeover by revising the workpiece information and replacing with a suitable center attachment.

A center attachment corresponds to multiple hole diameters. This will save running costs even with workpieces for high-mix low-volume production.
