4.4 Mounting the magnetic ring
Magnetic ring MR320
Slide magnetic ring MR320 onto the shaft and then tighten grub screw M6
to fix it to the shaft.
1. Ensure sliding fit between shaft and MR320.
2. Mount MR320 without force and without strain. Possible forces should
go to the metal flange. Avoid knocks on the magnetic ring.
3. Provide for a relief groove in the solid shaft (see
Fig. 8
).
Magnetic ring MRI01
Slide magnetic ring MRI01 onto the shaft and then tighten grub screw M4
to fix it to the shaft.
1. Ensure sliding fit between shaft and MRI01.
2. Mount MRI01 without force and without strain. Possible forces should
go to the metal flange. Avoid knocks on the magnetic ring.
3. Provide for a relief groove in the solid shaft (see Fig. 8 ).
