1) Using the 360'-rotating damping control dial, the rangeof shock absorption can be adjusted by the useraccording to the impact velocity.
2) Prepares for another cycle by quickly retrieving the pistonroad with a specially designed spring.
3) Extends the life span of the product by preventing thecorrosion with finishes on the outer cylinder andcorroding the chrome plating on the piston road.
4) The thermal energy is established based on theatmospheric temperature of 20'C.

1. To prevent oil leakage, do not slant the unit more
than 1。.
2. To prevent shaking during operations, fasten the
lock nut tightly.
3. To prevent Full Load, install the pistol to stop
1~1.5mm short from the end of the stroke.
4. Run regular maintenance to check the unit is
performing its full capacity.

Comment) �The outer measurements are subject to change for improvements without notifications.
As a kinetic object with a certain mass collides to the piston, the piston backs up into the inner cylinder to gradually chain the orifice. Then the activating
fluid inside the cylinder is pushed out through the orifice into the outer cylinder and flows into and stored in the top of the inner cylinder through the fluid-
retrieving opening. The excessive activating fluid is temporarily stored in the accumulator.
When the object is removed, the piston quickly retrieves back by a return spring so that the activating fluid flows into the inner cylinder through the check
valve.
Applying the Multiple-Orifice principle, the SB Series is equipped with
multiple orifices on the fixed inner tube and inserted with a long-grooved out
tube so that the out tube can be screwed to adjust the total cross section.
It not only can be adjusted according to changes of the shock energy, but
also indicates the size of the energy from 0 to 8 according to the degree of
the openness.
Adjustable Shock Absorber
It refers to the products with fixed orifices produced by unifying the
advantages of the Hydro Shock and the Adjustable Shock Absorber. It not
only absorbs a wider range of shock energy, but also emits the shock energy
as heat energy more efficiently.
Also, this specially designed orifice that does not require adjustments
maintains the pressure evenly throughout the changes of the shock energy to
stop the kinetic object softly.
Principles and Structures of the Shock Absorber
Graph① shows the ideal deceleration while maintaining the
lowest impact force,② shows the low effective state of the self-
compensator Shock Absorbers, ③ shows the high effective weight state of the self-
compensator Shock Absorbers and ④ shows a dashpot.

Comment) �The outer measurements are subject to change for improvements withoutnotifications.
The Effective Weight refers to the actual amount of shock energy
absorbed by the Shock Absorber from the moment the kinetic
object collides to the Shock Absorber until it stops. As shown in
Illustration ⓐ, when the actual mass of the kinetic object is minor
but the impact velocity is considerable (faster than 3m/sec), the
resistance increases soon after the collision. Therefore, it is
necessary to increase the cross section of the orifice.
As shown in Illustration ⓑ, when the impact velocity is very slow
(slower than 0.5m/sec) but the mass is considerably heavy or has
an additional propelling force, the resistance increases at the end
of the stroke. Therefore, it is necessary to decrease the cross
section of the orifice.
A) Light Mass and Fast Velocity
Resistance / Increase the cross section of the orifice / Stroke
B) Slow Velocity and Heavy Mass
Resistance / Decrease the cross section of the orifice / Stroke
As shown in Illustrations ①, ②, ③ and ④, even though
the kinetic objects have equal mass and velocity, the
actual shock energy of the Shock Absorber changes
significantly depending on the addition of the additional
propelling force and on the location of the Shock
Absorber.
Firstly, when comparing examples ① and ②, it is shown
that the shock energy of ② is 1.5 times that of ①,
because ② has the addition of the additional propelling
energy.
Also, when comparing examples ③ and ④, it is shown
that the actual shock energy of ③ increases 16 times,
because ③ is located differently although ③ and ④ has
equal amount of kinetic energy.
As explained above, although the mass and the velocity
are equal, the actual shock energy on the Shock
Absorber can change significantly according to each
situation. Therefore, not only the total energy but also the

Precautions
Warning① The installation must be designed so that the impact body is perpendicular to
the shock absorber’s axial center. An angle of deviation that exceeds 1。will place an excessive load on thebearings, leading to oil leaks within a short period of operation.
② If oscillating impacts are involved, the installation must be designed so thatthe direction in which the load is applied is perpendicular to the shockabsorber’s axial center. The allowable oscillating angle until the stroke end must be θ2 < 1。. In this
case, the minimum installation radius will be as shown in the table below. If theangle exceeds 1。, it could lead to oil leaks.
Installation conditions for rotation impact
③ A guide is necessary if the impact body involves vibrations.If the impact body involves vibrations and if a force that is perpendicular to theaxis is applied to the piston rod, a secure guide must be provided for theimpact body.
④ The rigidity of the mounting frame must be taken into consideration.If the mounting frame lacks rigidity, the shock absorber will vibrate after animpact, causing bearing wear and damage. Apply the following formula tocalculate the force that is applied to the mounting frame:
Caution① The maximum absorption energy indicated in the specifications for both
Series RB and RBL cannot be brought into full play unless the entire strokeis used.
② The contact surface of the impact body with which the piston rod comes incontact must be highly rigid.In the case whthout a cap, a high surface compression load is applied to thecontact surface of the impact body with which the piston rod comes incontact. Therefore, the contact surface must be highly rigid(hardness ofHRC35 or more).
③ Be aware of the retum force of the impact body. If used in a conveyou drive, affer the shock absorber has absorbed energy, itcould be pushed back by the spring that is built in. Refer to the column for thespring force in the specifications.
Caution① Make sure that the retaining nut is not loose.
The shock absorber could become damaged if it is used in a loose state.
② Pay attention to any abnormal impact sounds or vibrations.If the impact sounds or vibrations have become abnormally high, the shockabsorber may have reached the end of its service life. If this is the case, replacethe shock absorber. If use is continued in this state, it could lead to equipmentdamage.
③ Inspect the cap for any cracks or wear.If the shock absorber comes with a cap, the cap could wear first. To preventdamage to the impact body, replace the cap often.
Warning① Do not expose the shock absorber to machining oil, water, or dust.
Series RB cannot be used under conditions in which fluids such as machiningoil or water are present in atomized form or come in direct contact with thepiston rod, or in which dust could adhere to the piston rod. Such conditions
would cause malfunction.
② Do not operate the shock absorber in an environment that poses the risk of corrosion.Refer to the respective structural drawing for the type of material that is used inthe shock absorbar.
③ Do not use the shock absorber in a clean room.As it could contaminate the clean room.
Warning① Before perfoming installation, removal, or stroke adjustment, make sure to
cut the power supply to the equipment and verify that the equipment hasstopped.
Caution① Tightening torque of mounting nut should be as follows.
If the tightening torque that is applied to the nut exceeds the value given above,the shock absorber itself could become damaged.
② Do not scratch the sliding portion of the piston rod or the outside.Failure to observe this precaution could scratch or gouge the sliding potion ofthe piston rod, or damage the seals, which could lead to oil leakage andmalfunction. Furthermore, damage to outside threaded portion of the outertube could prevent the shock absorber from being mounted onto the frame, orits intermal components could deform, leading to a malfunction.
③ Never turn the screw on the bottom of the body.It is not an adjustment screw, as this will cause oil leakage.
