Industrial Shock Absorber Designs Self-Compensating ACE Controls self-compensating shock absorbers are highly engineered, fixed, multi-orifice units that decelerate moving weights smoothly regardless of changing conditions, and require no adjustment. These versatile performers offer wide effective weight ranges for handling a wider range of applications and increased velocities. As a moving load impacts the shock absorber the piston travels through the stroke and forces hydraulic fluid through the multi-orifice inner tube. The total orifice area decreases at a rate consistent with the decay...

Innovation in Deceleration and Motion Control For over 44 years ACE Controls has provided superior deceleration and motion control products to meet the needs of the automotive, steel, machine tool, lumber, theme park, medical, and other industries. Industrial shock absorber innovations include: the adjustable and selfcompensating models, as well as the more recent award winning SC2 Heavyweight Series which elevated shock absorber effective weight capacity and energy absorption capability to new heights. In 1999 ACE introduced the ultimate in shock absorber design…the award winning MAGNUM®...

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 Any moving object possesses kinetic energy as a result of its motion. When the object changes direction or is brought to rest, the dissipation of this kinetic energy can result in destructive shock forces within the structural and operating Kinetic energy increases as an exponential function of velocity. The heavier the object, or the faster it...

Cylinder Cushions and Dashpots (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 Springs and Rubber Bumpers (High stopping forces at end of stroke). The moving load is slowed down by a constantly rising reaction force up to the point of full compression. These devices store energy rather than dissipate it, which causes the load bounce back.

General Information ACE pioneered the use of one piece / closed end bodies and inner pressure chambers in its range of shock ab­ orbers. This s design concept provides an extremely strong construction which can withstand much higher internal pressures and overload forces without mechanical damage. Consider what happens if the shock absorber is accidentally overloaded or in the unlikely event of partial oil loss due to excessive seal wear or damage. Compare the internal design used by ACE with that of some of its competitors: ACE Shock Absorber Other Shock Absorber Snap Ring (Outer body and...

Effective Weight Effective weight is an important factor in selecting shock absorbers. A shock absorber "sees" the impact of an object in terms of weight and velocity only; it does not "see" any propelling force. The effective weight can be thought of as the weight that the shock absorber "sees" on impact. Effective weight includes the effect of the propelling force on the performance of the shock Failing to consider the effective weight may result in improper selection and poor performance of the shock absorber. Under extreme conditions, an effective weight that is too low may result in...

Quality Construction ACE Controls has not only established a reputation as the world leader in deceleration technology, but in quality as well. ACE was awarded ISO 9001 quality status in 1994, and attained ISO 9001:2000 status in 2002. The employees of ACE Controls are dedicated to building a quality product, assuring customer satisfaction and delivering on time. As a result of this employee focus, ACE Controls shock absorbers are built to the highest standards. A majority of ACE shock absorber bodies and inner pressure chambers are fully machined from solid alloy steel. A completely...

Self-Compensation Self-Compensating Shock Absorbers In cases where non-adjustability is beneficial but the features of an adjustable shock absorber are required, self-compensating shocks meet both needs. With a range of effective weight, a self-compensating shock absorber will provide acceptable deceleration under changing energy conditions. The orifice profile, designed by a computer that constantly arranges the size and location of each orifice while inputting changing effective weights, neutralizes the effect of changing fluid coefficients, weight, velocity, temperature and fluid...

Selection Procedure ACE Controls offers industrial and safety shock absorber CAD Files for downloading from the ACE web site at www.acecontrols.com. The CAD File software is titled interfACE. ACE’s Windowsbased sizing software, ACESIZE, is also available for downloading. Both software packages, along with the CAD Files are also available on a CD-ROM. See page 85 for additional information. The shock absorber selection procedure below has been made available for customers who prefer to select without the aid of computer-related technology. To select the best shock absorber for your...
