Miniature Shock Absorbers
SC300M-4

Long stroke and soft impact

Self-Compensating, Soft-Contact
Energy capacity 300 in-lbs/cycle
Stroke 0.75 inch

Ideal for soft damping: the SC found in the model code from the ACE product family SC190 to SC925 stands for 'soft contact'. These miniature shock absorbers manufactured from one solid piece are designed in such a way that they can be setup with a linear or a progressive braking curve. The soft damping character is thanks to the special, long strokes which produce smooth deceleration and low reaction forces.

These maintenance-free, ready-to-install hydraulic machine elements are equipped with an integrated positive stop. The use of side load adapter allows impact angles of up to 25°. Thanks to the designed overlapping effective weight ranges, these dampers cover an effective load range of 3 lbs. to 4,400 lbs! Self-compensating shock absorbers react to changing energy conditions, without adjustment.

These miniature self-compensating shock absorbers from the SC190 to SC925 product family are used in industrial, automation and machine engineering and primarily in the areas of handling and automation.
