*1 The applicable rod size affects the holding force, so use a rod with the rod size tolerance shown in the table above.
*2 The holding force (max. static load) shows the maximum capability and does not show the normal holding capability. Be sure to select a cylinder using
the method described in Model Selection (page 5).
*When inserting the rod into the lock unit, be sure to avoid damaging the seal and inner periphery of the product. For details, refer to page 44.
A safety mechanism can be designed if required.
It can also be combined with a wide variety of actuators.
¡Prevents the workpiece from falling
¡Retains the workpiece position even when the air supply

Precautions on Model Selection
Selection Example
Caution
Load Condition Operating Pressure
1. In order that the originally selected maximum speed shall not
be exceeded, be certain to use a speed controller to adjust the
total movement distance of the load so that movement takes
place in no less than the applicable movement time.
The movement time is the time that is necessary for the load to
travel the total movement distance from the start without any
intermediate stops.
2. In cases where the cylinder stroke and the movement distance
of the load are different (double speed mechanism etc.), use
the movement distance of the load for selection purposes.
3. The following selection example and procedures are based on
use at the intermediate stop (including emergency stops during
operation). However, when the cylinder is in a locked state,
kinetic energy does not act upon it. Under these conditions,
use the load mass at the maximum speed (V) of 100 mm/s
shown in graphs bto mon page 6 depending on the
operating pressure and select models.
• Load mass : m= 50 kg
• Movement distance : st = 500 mm
• Movement time : t= 2 s
• Load condition : Vertical downward = Load in direction of
rod extension
• Operating pressure : P= 0.4 MPa
Step z:From graph z,find the maximum movement speed of
the load
\ Maximum speed : V≈350 mm/s.
Step x:Select graph nbased upon the load conditions and
operating pressure, and then from the intersection of the
maximum speed V= 350 mm/s found in Step z, and
the load mass m= 50 kg.
\ ø63 Select an MWB63 or larger bore size.
Find the maximum load speed V.Step Mz
Find the maximum load speed: V[mm/s] from the load movement
time: t[s] and the movement distance: st [mm].
Find the bore size.
Step Mx
Select a graph based upon the load condition and operating
pressure, and then find the point of intersection for the maximum
speed found in Step zand the load mass. Select the bore size
on the above the point of intersection.
Load in the direction at the right angle to rod

Example) Load limit at rod end when the air cylin-
der ø63 is actuated at 500 mm/s.
Extend upward from 500 mm/s on the
horizontal axis of the graph to the inter-
section point with the line for a tube bore
size of 63 mm, and then extend leftward
from this point to find the load of 80 kg.
*1 The allowable kinetic energy of the cylinder is
shown without the intermediate stop or emer-
gency stop. Refer to page 5 or 6 for the kinetic
energy with intermediate or emergency stop.

Working Principle
Unlocked (when air pressure is applied)
When air is supplied to the unlock port, the piston moves
downward, the brake pad is opened by the tapered portion
at the bottom of the piston and the piston rod will be free to
move. This is the lock released state.
*Check that there is no air leakage from the unlock port.
When the air supplied to the unlock port is exhausted, the
piston moves upward due to the spring force at the bottom
of the piston and rigidity of the brake pad. Then, the brake
pad is closed and holds the piston rod, locking its
movement. This is the locked state.
Locked (when air is exhausted)
When the lock release bolt is screwed-in, the piston moves
downward, the brake pad is opened by the tapered portion
of the piston and the piston rod will be freed. This holds
the lock in the released state. Refer to page 41 for how to
return to the locked state.

*Never dissemble the lock unit. It should be replaced as a unit. Refer to
page 42 for the part numbers for placing an order. The seal kit shown
above contains the rod seal for the cylinder and lock unit. Order the seal
kit suitable for the cylinder bore size.
*The seal kit shown above includes a grease pack.
(ø32, ø40, ø50: 10 g, ø63, ø80: 20 g, ø100: 30 g)
