Decel Cushioned Cylinder
Fully Cushioned Load Stopping Capacity in Pounds*
NOTE:
• All dimensions not shown are per STD NFPA dimensions
• For cylinders with (1) Decel Cushion AOL dimension wil be "MB"-"J".
The Decel Cushioned cylinder increases the kinetic
energy absorption capability by increasing the
effective cushion spear length in the cylinder.
The Decel Cushioned cylinder increases the standard
cushion spear length by 100%, allowing an increase
in kinetic energy absorption capability by two times.
Decel Cushioned cylinder envelope
dimensions are not NFPA dimensionally
interchangeable over the stroke length.
