Piston tube design for maximum energy absorption

Self-Compensating, Piston Tube Technology
Energy capacity 650 in-lbs/cycle
Stroke 0.59 inch

Added safety with accumulator technology: The larger 'soft contact' models from the SC²300 to SC²650 are available with up to three times the energy absorption compared to similar sizes of standard shock absorbers SC190 to SC925, due to the ACE piston tube specialty. Furthermore, the membrane accumulator serves as a compensation element for the oil displaced in the shock absorber and replaces the standard use of absorber materials. This increases process safety even further.

The shock absorbers, which are perfect for rotary actuators for example, are available in progressively stepped effective weight ranges with an integrated positive stop. They are maintenance-free and ready for direct installation. The side load adapter option allows impact angles of up to 25°. They offer soft contact deceleration where initial impact reaction forces are very low, with the advantages of self-compensation to react to changing energy conditions, without adjustment.

These miniature shock absorbers offer high performance levels with a long service life and are particularly popular for material handling, mounting very close to pivots and automation tasks.
