Cast-iron series 1MJ6 and 1MJ7, frame sizes 180 M to 315 M

Type of construction IM B3

Frame sizes 180 M/L, 225 S/M, 280 S/M and 315 S/M have frame feet each with 2 drilled holes at NDE.

Types of construction IM B5 and IM V1

For flange dimensions, see flange size (Z = the number of retaining holes)

Type of construction IM B5 / IM V1(only up to frame size 315 M)

The motors are supplied with two fitted eyebolts conforming to IM B5, whereby one can be repositioned to conform to IM V1 or IM V3. It is important to note that stress must not be applied perpendicular to the ring plane.
