Shock Absorber Function

Shock Absorber Function
Virtually all manufacturing processes involve movement of some kind. In
production machinery this can involve linear transfers, rotary index motions,
fast feeds etc. At some point these motions change direction or come to
a stop.
Any moving object possesses kinetic energy as a result of its motion and
if the object changes direction or is brought to rest, the dissipation of this
kinetic energy can result in destructive impact forces within the structural 9
and operating parts of the machine.
Kinetic energy increases as the square of the speed and the heavier the
object, or the faster it travels, the more energy it has. An increase in produc-
tion rates is only possible by dissipating this kinetic energy smoothly and
thereby eliminating destructive deceleration forces.
Older methods of energy absorption such as rubber buffers, springs,
hydraulic dashpots and cylinder cushions do not provide this required smooth
deceleration characteristic – they are non linear and produce high peak
forces at some point during their stroke.
The optimum solution is achieved by an ACE industrial shock absorber.
This utilises a series of metering orifices spaced throughout its stroke length
and provides a constant linear deceleration with the lowest possible
reaction force in the shortest stopping time.

load is decelerated with the lowest possible force in the shortest possible
time eliminating damaging force peaks and shock damage to machines and
equipment. This is a linear deceleration force stroke curve and is the curve

reduce noise pollution.

Built-in Safety
12
Industrial shock absorbers and automobile braking systems have two
crucial functional similarities:
1. Both should bring a moving mass quickly and safely to rest
without any recoil or “bounce back”.
2. Both must never suddenly fail without warning.
ACE industrial shock absorbers are built to the highest quality.
Shock absorber bodies and inner pressure chambers
are fully machined from solid high tensile alloy steel.
This gives a completely closed end one-piece pressure Piston Rod
chamber with no seals or circlips being necessary. high tensile steel
hardened and
corrosion resistant.
The advantage of this design concept is that
the ACE shock absorber is able to withstand much
higher internal pressures or overload without
damage, giving a very high safety margin.
The chance of a sudden failure due to
overload etc. is effectively ruled out. Bearing

Miniature Shock Absorbers MC5 to MC75
Self-Compensating
18
ACE miniature shock absorbers
are maintenance-free, self-contained
hydraulic components. The model range
MC5 to MC75 have a very short overall
length and a low return force.
The shock absorber is filled with a tem-
perature stable oil and has an integrated
positive stop. They are ideally suited for
small, fast, handling equipment, rotary Elastomer Insert
actuators, pick and place mechanisms (MC25M and MC75M)
and similar small automation equipment.
A wide choice of metering hardnesses
enable these units to cover applications
with effective weights ranging from
Piston Rod
0.3kg to 36 kg.
The MC30M-Z model enables direct Positive Stop
installation inside a pneumatic pressure
chamber (up to 7 bar), due to the inno-
Main Bearing
vative ACE stretch membrane.
