How to Adjust Brake Gap

The brake gap adjustment can only be done once.
Note) If the gap is below of that of the adjustable gap, do not attempt to adjust the gap. This may result in malfunctions.

<Gap adjustment procedure>

・

For standard type brake

(1) Loosen Fan cover fixing screw [5] and remove Fan cover [7].
(2) Check that the brake gap is equal to or more than the adjustable gap

of <

■

Brake Specifications> under no energization state.

(3) Loosen Fan fixing screw [10] and remove Fan [8] .

* The brake for 0.1 kW has no fan.

・

For water-resistant type brake

(1) Loosen Fan cover fixing screw [5] and remove Fan cover [7].

Then, loosen Fan fixing screw [10] and remove Fan [8] and V-Ring [24].

※

0.1kW has no fan cover, fan, and v-ring.

(2) Loosen Cover fixing bolt [21] remove Brake cover [22].

※

Be sure the oil seal does not get damaged as it may lose
water-resistant ability.

(3) Check that the brake gap is equal to or more than the adjustable gap

of <

■

Brake Specifications> under no energization state.

・

Common procedure

(4) Remove any wear debris with an air gun.

*

(5) Remove Plate screw [14] .

　

(6) Clean attachments on the screw part.

* If the screw has a scratch, etc. , please replace it with a new one.

(7) Remove Plate [15] .

* Pay attention so that friction surfaces of parts are not made dirty.
* Check that friction surfaces have no scratch or other abnormalities.

(8) Pull out all Shims [13] .
(9)

* Be cautious not to lose the spring.

(10) Clean the screw hole of Magnet ASSY [11] with an air gun.

* Check the passing state of the screw after cleaning.

(11) Apply adhesive on the screw to prevent looseness to the screw hole.

(Recommended adhesive: Loctite 243 by Henkel)

(12)

* Refer to the <

■

Brake Specifications> for the tightening torque.

(13) Check that Brake gap [18] is within the initial gap value on the

<

■

Brake Specifications> table.

(14) Check the operations of the brake (Brake release/brake actuation).

Even though the gap is not exceeded the limitation gap, the brake gap can be adjusted if it is more than the
adjustable gap.

If the disk is worn out after long term usage and the Gap [18] between Magnet ASSY [11] and Armature [17] exceeds
the gap limitation value described in the brake specifications, malfunctions of the brake may occur. Please Adjust the
brake gap as follows.

The gap is the space between Magnet ASSY [11] and Armature [17]
under no power

Remove Collar [12] and Armature [17] and clean the wear debris
attached to Magnet ASSY [11] with an air gun.

Put all parts except for the shims back to the original positions and
tighten Plate screw [14] .
