Balancing grade G | ew 1] 2] mm/s | Rotor Types - General examples |
G 40 | 40 | - Car wheels, wheel rims, wheel sets, drive shafts. - Crankshaft-drives of elastically mounted fast four-cycle engines (gasoline or diesel) with six or more cylinders4). - Crankshaft-drives for engines of cars, trucks and locomotives. |
G 16 | 16 | - Drive Shafts (propeller shafts, cardanshafts with special req - Parts of crushing machinery. - Parts of agricultural machinery. - Individual components of engines (gasoline or diesel) for cars, trucks and locomotives. - Crankshaft-drives of engines with six or more cylinders under special requirements. |
G 6,3 | 6,3 | - Parts or process plant machines. - Marine main turbine gears (merchant service). - Centrifugal drums. - Fans - Assembled aircraft gas turbine rotors. - Fly wheels. - Pump impellers. - Machine-tool and general machinery parts. - Normal electrical armatures. - Individual components of engines under special requirements. |
G 2,5 | 2,5 | - Gas and steam turbines, including marine turbines (merchant service). - Rigid turbo-generator rotors. - Rotors. - Turbo-compressors. - Machine-tool drives. - Medium and large electrical armatures with special requirements. - Small electrical armatures. - Turbine-driven pumps. |
G 1 | 1 | - Tape recorder and phonographs (gramophone) drives. - Grinding-machine drives. - Small electrical armatures with special requirements |
G 0,4 | 0,4 | - Spinles, disks and armatures of precision grinders. - Gyroscopes. |
1] w=2xn / 60N / 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. |
