Installing to your equipment

 

 

Installation direction 

A hollow-shaft gearhead can be installed by using either its front or rear side 
as the mounting surface.

Motor

Rear

Hollow-shaft gearhead

 

 

Installation method 

• 

Affix the gearhead onto a smooth, machined metal surface using the 
supplied hexagonal socket head screw set.

 

• 

Drill mounting holes in the metal plate for installation of the gearhead.

 

• 

Using the supplied hexagonal socket head screw set and the four mounting 
holes provided in the gearhead’s mounting surface, affix the gearhead in 
such a way that there is no gap along the equipment’s mounting surface.

 

• 

The 

GFS6G FR

 does not come with hexagonal nuts. Insert flat washers 

and spring washers on the head side of screws. 

• 

Using the supplied safety cover mounting screw (M3-2 pcs.), install the 
supplied safety cover on the hollow output shaft opposite the shaft end on 
which the load shaft is installed. 

Maximum applicable plate thickness 

The values in the table are based on the use of the hexagonal socket head 
screw (supplied).

When installing the gearhead using its rear face, be certain 
that dimension E does not exceed the specified value so 
that contact between the mounting plate and motor is 
prevented.

Installing a load 

 

Installing the load shaft

 

• 

When installing the load shaft onto the hollow output shaft of the gearhead, 
align the centerlines of the hollow output shaft and load shaft. 

• 

The hollow output shaft has a key groove. Machine a key groove in the 
load shaft and then affix the two shafts using the supplied parallel key. 

• 

The recommended tolerance of the load shaft is “h7.” 

• 

Use a stepped load shaft and affix it using an end plate if large, frequent 
impacts are expected due to instantaneous stops or when the overhung load 
is large. For details, refer to “Affixing method using end plate”.
