Shock Absorbers are widely used in industry where the speed, direction or movement of objects must be changed or stopped. Without suitable methods of control the kinetic energy inherent in many moving objects, which occur in manufacturing, can result in increased machine wear and even machine damage.
Ideally any method of "shock absorption" should provide two key features
1) Bring the moving object to rest quickly, smoothly and without rebounding forces 2) In-bult reliabilty and safety
Shock absorbers are able to quickly convert the kinetic energy of a moving object into heat and to dissipate this into the air, and provide a constant linear deceleration of an object throughout its entire impact stroke, to quickly smoothly and quietly bring a moving object to rest with the lowest reaction force and in the shortest time. All of these features mean increased manufacturing productivity, extended machine life, and improved efficiency.
Adjustable collar at base of shock absorber enables setting of optimum deceleration of unit to suit application. Ensures smooth deceleration of moving parts.
Self compensating fixed shock absorbers are consistent and reliable dampening force or linear deceleration, throughout entire impact stroke.
Perfect for small applications, this small size shock aborber is for M14 - M20 threads.
Hardened blackened steel industrial shock absorber. Adjustment collar at base to enable setting of optimum deceleration of unit to suit application.
Solid rollers with smooth surface and solid body making them ideal for moving components. Nitrile, neoprene or urethane material. Widely used for material and component handling in automated processes.
Self compensating shock absorber 68001
Our self-Compensating Shock Absorbers are effective for a stated range of Effective Mass (Me), and are self-compensaying within this range - see selection charts. As long as the applications effective mass remains within the given range then no additional adjustment is required for changes in weight, speed or propelling force.
See models: 68001, 68002, 68003, 68004, 68008, 68012
Self Compensating shock absorber 68002
Each Self-Compensating Shock Absorber is available in three standard max. Impact speed (v-m/s) variations:
1 - high impact speed
2 - medium impact speed
3 - low impact speed
For specific max. impact speed values please refer to the selections charts and the specific product tables.
For hard impact at the start of a stroke it is advisable to choose a high impact speed model, for hard set down at the end of a stroke it is advisable to choose a medium or low impact speed model, or to move up to the next higher bore size.
Adjustable shock absorber 68020
Set collar to 0 at inital installation
After a few cycles adjust collar setting to suit application
Adjustable shock absorbers have an adjustment collar at their base (with a scale of 0-9), which enables adjustment of the Shock Absober's optimum deceleration to suit the application.
After initial installation, the Shock Absorber should be cycled a number of times to settle, and then the adjustable collar turned to the desired position for the application.
We advise the use of external mechanical stops with all of our Shock Absorbers, typically within 1 to 0.5 mm from the end of the stroke. Alternatively, we have a range of stop collars available which can be mounted directly to the shock absorber body (see our part 68030). Stop collars are available for our M8 to M36 threaded models, they can be used both to adjust stroke and also to fix the end position of the load.
Basic mounting of shock absorbers is through the use of its threaded body, and lock nuts supplied. Alternatively Shock Absorbers can be flange mounted, please see our available flange mounting adaptors part 68032 for our M36 and M42 threaded models.
Shock Absorbers are supplied with muffler caps as standard. Muffler caps can be removed from the Shock Absorber Piston by heating them with a lighter and pulling away using a pair of plyers.
Traditional buffering methods:
Costs associated with outdated cushioning methods:
Traditional buffering methods can only dissipate a small percentage of the kinetic energy of a moving object, the remainder is stored (rather than dissipated) as elastic energy which results in high resistance and rebounding forces toward the end of the impact stroke.
Wixroyd Shock Absorbers are designed to stop a moving object smoothly and quietly from the beginning to the end of its impact stroke. Their design enables a constant resistance force or linear deceleration throughout the impact stroke, quickly converting the kinetic energy of the moving object into hear which is quickly dissipated into the air. A linear deceleration curve, as achieved by our shock absorbers, brings an object to rest in the shortest time while reducing damaging impact forces.
Energy Capacity: Shock Absorbers can absorb more energy, without increasing deceleration or reaction forces.
Stopping Force: Shock Absorbers provide smooth decelaration of parts, which means less machine wear and hense reduced maintenance.
Stopping Time: Shock Absorbers bring moving loads to rest more quickly, increasing productivity.
Dashpots: Produce learge peak forces at beginning of impact stroke, abruptly slowing load - however braking force quickly declines.
Springs & Rubber Buffers: Energy is stored rather than dissipated, resulting in rebounding of the load.
Air Buffers: Initial braking force is low, but due to the compressibility of air it increases sharply toward later stages of stroke, resulting in inconsistent braking force.
