Zimmer Shock Absorbers with Spiral Groove Technology

Amcats offers Zimmer Shock Absorbers. Zimmer Shock Absorbers have been developed with the aim of ideally converting kinetic energy into thermal energy. Intense cooperation from industrial establishments and long-term practical experience with the use of damping elements have led to the development of the industrial shock absorber with Spiral Groove Technology. Usage of this system contributes to a company's process reliability, product quality and its profitability.

What is Spiral Groove Technology?
In contrast to the conventional industrial impact damper, the exhausting channel (throttle) of the Power Stop Shock Absorber is directly incorporated in the piston. Because of its continuous conicity (spiral groove) there is a dynamic force over the total stroke. This results in is maximum energy absorption at minimum power, making the shock absorber more capable, durable & adaptable and free of pull.

Smooth braking (without sudden cross section constrictions)
Higher power absorption due to maximum capacity usage at each piston position
Individual manual adjustment for each matter of application
Small construction space due to substantially higher energy absorption
Minimum consumption rates by optimal bearing
Possible to insert in pneumatic pressure chambers
Higher operation safety and longer life because of oil reserve
Stainless steel piston rod ensures minimum wear-out
Integrated oil reserve compensates for the minimal oil losses
High tensile case hardened piston and tube to manage extreme charges upto 1000 bar
Separate tube and casing guarantees perfect operation of the impact damper at the maximum tightening moment of the counter nut

A Comparison

Conventional Impact Damper	Zimmer Power Stop Shock Absorber
A conventional impact damper squeezes the oil out through the throttle bores which are inserted on one side of the tube. The force of oil is diverted and enormously strained by the high velocities of hitting. Top compressions produce vibration and reduce the life of elements involved at the damping process. The damping behaviour is determined by the number of throttle bores and the energy absorption is restric	The exhausting channel of the Power Stop is directly inserted in the piston as spiral groove. During damping the piston dives into the oil bath and picks up over the exhausting channel the oil to be squeezed. The mechanical strain of the oil remains low because of the rotary rising spiral groove. The section form allows a continuous throttling activity and guarantees smooth damping. The result is that maximum energy absorption takes place across the entire damping stroke.

Lesser energy absorption For example: Energy absorption of construction series M33 x 1.5, stroke 30 mm: 100 Nm	Upto 300% more energy absorption For Example: Energy absorption of construction series M33 x 1.5, stroke 30 mm: 320 Nm

Types of Shock Absorbers

Depending on the type of operation they are classified as follows:

Power Stop	Damper employed under constant load condition
Emergency Stop	Damper employed when operation is intermittent and used for stopping in case of Emergency. Not suitable for continuous loads.
Mini Stop	Miniature shock absorbers giving highest efficiency in smallest of spaces

Depending on whether the load is slow moving heavy load or a fast moving shock absorbers have been classified into 3 levels

Type S (Soft)	Applicable for High velocity of hitting like free falling masses
Type M (Medium)	Used where medium velocities of hitting are observed like pneumatic driven masses
Type H (Hard)	low impact velocities employed in slow moving heavy masses

Continuous Innovation
The rapid development requires new technologies permanently, in order to live up to the increasing demands concerning the components of movable systems. This reason is enough to develop further innovative technologies, which even improves and enhances the productivity of the successful shock absorbers.
The new I-Class edition, which allows a longer traverse path next to a constant size of construction; or the new Oil Alert system for a still higher security during extreme periods of operation; or for that matter the latest miniature shock absorber MM6.
