Table 3- 11 Solid shaft
Frame size Shaft length l [mm] Shaft diameter d [mm]
1FW315 ☐ 140 65 m6
1FW320 ☐ 170 90 m6
1FW328 ☐ 210 120 m6
The shaft version "solid shaft" can be ordered with a plain shaft end or with keyway
(according to DIN 6885-1).
Note
Shaft cover at NDE for the "hollow shaft" version
If the hollow through-shaft is not used by the customer and must be sealed at the NDE for
touch protection reasons, the motor can be supplied with a shaft cover at the NDE. Ordering
options: Order code T20.
See the dimension drawings for further details.
Direction of rotation
The positive direction of rotation is clockwise when viewing the drive end (flange side).
