Feature
● High increase efficiency.
The brake is released smoothly with low pressure by the new mechanism as hold the steel balls by the taper ring.
● Long life brake metal.
Using many steel balls to keep wide holding area of the brake metal, no unbalanced load by the center adjustment
mechanism, and the life of the brake metal will be long.
● No change braking power.
The brake is applied smoothly if no air, because braking power is made by the spring only.
And guarantee constant braking power during long time using by the spring of the low spring constant.
● Simple design.
No cumbersome projecting parts and easy installation.
● Compact cylinder.
Short length cylinder and compact style particular the braking part.
● Easy installation of the cylinder.
Easy installation cause of the compact style and direction of the piping port, cushion needle, brake release port,
manual release lever, etc.

Operating principles
●Brake release
Brake piston② move to right side by air, when supply the air to
the brake port..
●Brake lock
Brake piston② move to the left side by the spring⑥.
Steel balls③ move to center side cause of the bore become to
small according to move to left side the taper ring④, and the
piston rod is gripped by the brake metal⑤.
There are many steel balls to control wide surface.
And get the high holding force pressure efficiency cause of
rolling movement of the steel balls.

●Valve mount to same position of the unlocking port. In the case of Rod flange, valve is not mount at the position of "X" and "Z".
How to improve the stopping accuracy
Exhaust the air of the brake port as
soon as possible
Prevent the dispersion of the electric
control signal of the solenoid valve
for the brake
Keep fix the speed of the piston rod
●Install near the brake port and the
valve for the brake.
●When send the stop signal by the
sequencer take care the scan
time, and does not through the
sequencer circuit if disperse the
signal.
●Use the hydro converter when
change the speed. (When change
the load or use the rolling guide)
※(The axial length become long
cause of change the packing)
●Use the inner installable stopping
sensor.
If install on outside, use the small
dispersion type.
(Reed switch, Proximity switch,
etc)
●Use the rolling guide, not use the
slide guide.
●Install the rapid exhaust valve to
the brake port if the valve for the
brake is far and small.
●When need stabilize the stopping
accuracy, install the pressure
regulator to control the supply
pressure (about 0.3MPa) of the
release valve (SOL-3
●Use the fast reaction and small
dispersion solenoid vaive.
●Use the floating connector for the
hoot mount type and frange
mount type to prevent the center
gap.
●When the stopping pitch is under
50mm or the speed is fast,
release the brake before operate
the main valve.
(In this time, adjust the pressure
balance correctly to prevent jet
out the rod when release the
brake)
●If the rod stop near the end of the
stroke (under 50mm), use the no
cushion type.
