ISO balancing grades - explanation and examples
ISO balancing grades - explanation and examples. The two primary factors to determine permissible unbalance (also called the balancing tolerance) are the mass of the rotating part and the maximum operational speed. Calculating a balancing tolerance based on these parameters is realtively simple. However, these calculated tolerances are for the ...

Rotor Balancing Tutorial
Although the API standards generally specify the rotor unbalance using U, API 617 has a minimum limit on eccentricity that is invoked for rotor speeds in excess of 25,000 RPM where the balance tolerance is limited at 250 μm or 10 μinch. This limit is established in general by the capabilities of shop balance machines. SHOP BALANCING METHODS
