Miniature Shock Absorbers
PMCN225MH
Reliable protection from fluids and particulate
Self-Compensating, Rolling Diaphragm Technology, TPU Bellow
Energy capacity 360 in-lbs/cycle
Stroke 0.50 inch
This protection bellows, made of TPU (thermoplastic polyurethane), safely encapsulates the proven ACE rolling diaphragm from the outside environment. Aggressive cutting, lubricating and cleaning agents don't stand a chance and the function of the maintenance-free, ready-to-install shock absorber is retained. They are also available in full stainless steel.
The PMCN range is a good alternative to the SP type air bleed collar if no compressed air is available on the machine or system.
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.
