Shock absorbers in miniature format

Energy capacity 75 in-lbs/cycle
Stroke 0.40 inch

Ideal for compact, efficient designs: The miniature size of the product family MC5 to MC75 delivers very short overall lengths and low return forces.

The outer body of each shock, produced from one solid piece, is filled with temperature stable oil, offers a continuous outer body thread including a supplied lock nut and also has an integrated positive stop. These maintenance-free hydraulic machine elements from ACE are ready for immediate installation. A wide range of energy absorption and effective weight are further benefits in these compact units. Self-compensating shock absorbers react to changing energy conditions, without adjustment.

These self-compensating miniature shock absorbers are perfectly suited to use in applications such as rotary actuators, automation, light industrial manufacturing, material handling and packaging equipment, medical, electronics and robotics.
