capability. The versatile SC - Nor-Cal Controls

1 ACE Controls self- compensating shock absorbers are fixed, multi-orifice units that decelerate movingweights smoothly regardless of changing conditions, and require no adjustment. These versatile performersoffer wide effective weight ranges for handling a wider range of applications and increased a moving load impacts the shock absorber the piston travels through the stroke and forces hydraulic fluidthrough the multi-orifice inner tube. The total orifice area decreases at a rate consistent with the decay ofimpact velocity, resulting in true linear versatile SC2 Series offers soft contact in combination with self-compensat-ing performance.

2 Soft contact is suggested when a low initial reactionforce is recognized at impact. The self- compensating featureis utilized to obtain maximum energy standard adjustable ACE shock absorber is based on the mul-tiple-orifice design principle and includes a series of orificesmachined along the length of a fixed inner tube. The Magnum Groupadjustable shock absorber, shown to the right, has a stationarymetering tube, with an inner tube that rotates upon adjustment. Theseunique models offer dual adjustability by turning the stop collar or the hex socket adjuster at adjustable shock absorber offers flexibility in application design and selection an effective weight change is required, one simply adjusts the setting.

3 The total orifice areachanges, providing true linear models offer a wide range of effective weight. One model is capable of handlingnumerous revolutionary, award-winning SC2 Heavyweight design offers up to 950% of theeffective weight capacity and up to 280% of the energy absorption capability of stan-dard models. These durable units combine the piston and inner tube into a single com-ponent, the piston tube, which acts as both the pressure creating and pressure con-trolling device. The Heavyweight Series offers a full effective weight range for a widerrange of over 37 years ACE Controls has provided superior industrial deceleration products to meet the needs of theautomotive, steel, machine tool, lumber, theme park, medical, and other industries.

4 Industrial shock absorberinnovations include: the adjustable and self- compensating models, as well as the more recent award winning SC2 Heavyweight Series which elevated shock absorber effective weight capacity and energy absorption capability tonew heights. In 1999 ACE introduced the ultimate in shock absorber award winning Magnum Group,offering up to 390% of the effective weight capacity, plus up to 150% of the energy per cycle of standard Controls Inc. products are guaranteed to be free of defects in materials and workmanship.

In produc-tion machinery this can involve linear transfers, rotary index motions, fast feedsetc. At some point these motions change direction or come to a moving object possesses kinetic energy as a result of its motion.

9 When theobject changes direction or is brought to rest, the dissipation of this kinetic ener-gy can result in destructive shock forces within the structural and operatingparts of the energy increases as an exponential function of velocity. The heavier theobject, or the faster it travels, the more energy it has. An increase in productionrates is only possible by dissipating this kinetic energy smoothly and therebyeliminating destructive deceleration methods of energy absorption such as rubber buffers, springs, hydraulicdashpots and cylinder cushions do not provide this required smooth decelera-tion characteristic they are non linear and produce high peak forces at somepoint during their optimum solution is achieved by an ACE industrial shock absorber.
