Installation using mounting holes on the front face
1.
Drill mounting holes or tapped holes in the metal plate used to install the linear head.
The same machining dimensions for mounting holes apply to both the B type and F type.

2.
Affix the linear head using four screws (not supplied) in a manner leaving no gaps between the
linear head and metal plate.

3.3 Installing a load
Install the load using hexagonal socket head bolts (not supplied) through the tapped holes provided on the end
face of the rack.
When installing the load, always secure the rack with a wrench so that the rack will not receive rotational
force while the load is affixed.
Note
When installing the load, align the axial centerline of the rack with that of the load.

Note
Even if the radial load does not exceed the permissible value, it is recommended to still
install a guide, etc., to reduce or disperse the radial load.
