Cast-iron series 1LG6, frame sizes 280 S to 315 L

Type of construction IM B3

Frame sizes 280 S/M and 315 S/M/L have frame feet 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)

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.

* This dimension is assigned in DIN EN 50347 to the frame size listed.

¹⁾ Measured across the bolt heads.

²⁾ With order codes for connection box positions (K09, K10, K11) only fitted feet with 3 drilled holes with dimension “B” (406, 457 and 508 mm). BB will then be 666 mm.
