<Advantages and disadvantages of flange and torque arm installation>
Installing flange
Four bolts should be used.

(Reference value)
Install the the torque arm detent to the driven machine side.
Makes centering with the application easy. Requires a torque arm.

M14 69 { 7.0}
M16 108 {11 }
Because the torque arm sustains a reactive force from
rotation, consideration needs to be given to impact
loads particularly during startup and braking, Bolts
and plates that are sufficiently strong must be used. It
is best to use an optional torque arm.
To install the torque arm and reducer, fasten
them using spring washers and flat washers with
the installation bolts.

Fastening the Reducer and Torque Arm
4-4. Installing Flange/Torque Arm
Advantages Disadvantages
Can be installed directly on the device.
Centering with the application isrequired.
When the hollow bore is installed directly to the flange
of an application, it can cause motor burn-out or
bearing damage if it is off-center, so be sure to center
it properly.
There is an installation guide, as shown in the
diagram at the right. The dimension tolerance for
φ A
for the installation guide is h7 in the case of F3S. The
installation bolts are installed as shown in the diagram
at the right.
Torque Arm Installation Fastening to the application only requires
one detent.
Requires space for installing a torque
arm.
Saves space.
●
Requires four(4) tapped holes for
mounting to the application. (F series)
