Reliable protection from fluids and particulate

Self-Compensating, Rolling Diaphragm Technology, PTFE Bellow
Energy capacity 1,200 in-lbs/Cycle
Stroke 1.00 in

Hermetically sealed: the shock absorbers from the ACE PMC Protection series come with a compact, well-sealed cap.
This PTFE (Teflon) protective bellows cap extends product life by safely encapsulating the proven ACE rolling diaphragm from the fluids and abrasive particles. Aggressive cutting, lubricating and cleaning agents don't stand a chance. The shock remains maintenance-free and ready-to-install. Stainless steel versions are also available for extreme environments.
The PMC series is a good alternative to the SP type air bleed collar if compressed air is not easily available. Self-compensating shock absorbers react to changing energy conditions, without adjustment

Reliable protection against aggressive environments including fluids and abrasives, these self-compensating miniature shock absorbers are the first choice where conventional dampers wear out too quickly. Use them in harsh environments where cutting, cooling or cleaning agents can attack.
