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 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.

Hydraulic Dashpot (High stopping force at start of the stroke). With only one metering orifice the moving load is abruptly slowed down at the start of the stroke. The braking force rises to a very high peak at the start of the stroke (giving high shock loads) and then falls away rapidly. 2. Springs and Rubber Buffers (High stopping forces at end of stroke). At full compression. Also they store energy rather than dissipating it, causing the load to rebound back again. 3. Air Buffers, Pneumatic Cylinder Cushions (High stopping force at end of stroke). Due to the compressibility of air these have a sharply rising force characteristic towards the end of the stroke. The majority of the energy is absorbed near the end of the stroke. 4. ACE Industrial Shock Absorbers (Uniform stopping force through the entire stroke). The moving load is smoothly and gently brought to rest by a constant resisting force throughout the entire shock absorber stroke. The 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 provided by ACE industrial shock absorbers. In addition they considerably reduce noise pollution. ComparisonEnergy CapacityReaction Force (Stopping Force)Stopping Time Assumption: Same maximum reaction force. Result:The ACE shock absorber can absorb considerably more energy (represented by the area under the curve). Your advantage: By installing an ACE shock absorber production rates can be more than doubled without increasing deceleration forces or reaction forces on the machine. Assumption: Same energy absorption (area under the curve). Result:The reaction force transmitted by the ACE shock absorber is very much lower. Your advantage: By installing the ACE shock absorber the machine wear and mainte- nance can be drastically reduced. Assumption: Same energy absorption. Result:The ACE shock absorber stops the moving load in a much shorter time.Your advantage: By installing an ACE shock absorber cycle times are reduced giving much higher production rates.

The dynamic piston forces the hydraulic oil to escape through the metering orifices. The displaced oil is absorbed by the accumulator. A static seal system containing a U-cup and a wiper seals the shock absorber internally. The outer body and the pressure chamber are fully machined from solid with closed rear end. ACE Design for Higher Demands ACE Piston Tube Technology: The increased volume of displaced hydraulic oil provides 200% more energy absorption capacity in comparison with the standard design. The wider effective weight range enables these dampers to cover a much wider range of applications. The piston and inner tube are combined into a single component.ACE Stretch and Rolling Diaphragm System: By the proven dynamic ACE rolling diaphragm seal system the shock absorber becomes hermetically sealed and provides up to 25 million cycles. The rolling diaphragm seal allows direct installation into the end cover of pneu- matic cylinders (up to 7 bar). These technologies are used separately or combined on the MC150M to MC600M, SC 225M to SC2650M, SCS300 to SCS650 and on the models MC30M-Z and MA150M. * The load velocity reduces continuously as you travel through the stroke due to the reduction in the number of metering orifices (*) in action. The internal pressure remains essentially constant and thus the force vs. stroke curve remains linear.

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 chamber with no seals or circlips being necessary. 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. Self-Compensating Industrial Shock Absorbers are maintenance-free, self-contained hydraulic devices with multiple metering orifices which extend through the complete stroke length. After the moving load contacts the shock absorber the piston moves back creating an immediate pressure rise in the pres- sure chamber. The hydraulic oil behind the piston can initially escape through all the metering orifices. The number of metering orifi ces in action decreases proportionally to the distance travelled through the stroke. The impact velocity of the moving load is smoothly reduced. The internal pressure and thus the reaction force (Q) remain essentially constant thoughout the complete stroke length providing a constant deceleration rate or: Linear Deceleration Shock Absorber Body heavy construction massively built one-piece body with closed rear end. Fully machined from solid steel to ensure total reliability. Piston Tube with integral piston check valve and metering orifi ces. Fully machined from solid with closed rear end to withstand internal pressures up to 1000 bar. Seals only one dynamic seal. Hermetically sealed rolling diaphragm sealing system.

Issue 4.2009 Specifications subject to change1818 Impact velocity range: Ensure that effective weight of application is within the range of the unit chosen. Special range units available on request. Material: Shock absorber body: Steel with black oxide finish. Accessories: Steel with black oxide finish or nitride hardened. Hardened stainless steel piston rod. Locknut MC5 and MC9: Aluminium. W4 capacity rating: (max. energy per hour Nm/hr) If your application exceeds the tabu-lated W4 figures consider additional cooling i.e. cylinder exhaust air etc. Ask ACE for further details. Mounting: In any position. If precise end position datum is required consider use of the optional stop collar type AH. Operating temperature range: 0 °C to 65 °C On request: The MC Series are available with weartec finish (seawater resistant) or other special finishes. Miniature Shock Absorbers MC5 to MC75 Self-Compensating 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 actuators, pick and place mecha nisms and similar small automation equipment. A wide choice of metering hardnesses enable these units to cover applications with effective weights ranging from 0.3kg to 36 kg. The MC30M-Z model enables direct installation inside a pneumatic pressure chamber (up to 7 bar), due to the inno- vative ACE stretch membrane.
