Axled play of motor shaft:

•G, G1 versions – 0,35 mm

•G2 versions – 0,25 mm

•G3 versions – 0,5 mm.

Simultaneous radial and axled load on free shaft end, created by driving mechanisms (including weight of turning parts set on shaft) is acceptable. Point of axled load application is at L1+L39 distance; for AIR 80 G2 is 90 mm from supporting butt end of fastening flange. Mounting of turning parts with weight not more than mentioned above in the Table on free shaft end is acceptable. Parts weight center is located at distance of 0,67 (L1+L39); for AIR 80 G2 is 85 mm from supporting butt end of fastening flange. Mounting of parts with weight not more than mentioned above in the Table 2 is acceptable for motors with IM 2029 mounting version. Parts weight center is located at distance of 0,67 (L1 + L39); for AIR 80 G2 is 60 mm from supporting butt end of fastening flange. In case if weight of parts mounted on flange is more than abovementioned in the Table 2, pump should have its own support which will unload the motor flange. The motors can be manufacturing with other dimensions of free shaft end in accordance with confirmed by Manufacturer and Customer draft of shaft end, load values and centers of load application.
