Balancing is a specialist field and some basic insight into the subject can help improve product design, product quality, and production throughput.
Need to Work out A Balance Tolerance?
Universal Balancing’s Tolerance Calculator utilizes the ISO Balance Quality Grade G and combines it with part specific information to calculate a balance tolerance.
Iso Balance Quality G Grade
ISO Balance Quality G Grades are used to calculate balance tolerances in conjunction with the rotor weight and service speed (RPM).
|BALANCE GRADE G||EW 1] 2] MM/S||ROTOR TYPES – GENERAL EXAMPLES|
|1] w=2xn / 60-N / 0, if n is measured in revolutions per minute and w in radians per second. To simplify: Tolerance = Component Weight [kg] x Quality Grade x 9549 / Operational Speed [RPM]
2] In general, for rigid rotors with two correction planes, one-half of the recommended residual unbalance is to be taken for each plane.
