Stopper Cylinders

ST Series and
Global Series™

A Variety of Rugged Stoppers to Decelerate Conveyed Loads

Fabco-Air stoppers are ideal cylinders for conveyors and other machines that need to decelerate a load before impact.

ST Series Stoppers
Available in bore sizes from 32 to 50 millimeters, the ST Series comes in a variety of styles to address different requirements: round rod, non-rotating rod, rollers that adjust direction according to application needs, and four lever types. The stoppers feature a magnetic piston as standard, Buna-N bumpers at both ends to ensure a gentle stop and rugged aluminum extrusion construction. Options include shock absorbers for safety stops and magnetic sensors that mount easily to the cylinder when input signals are required for controllers. The stoppers operate at 145 psi (maximum) compressed air over a wide operating temperature.

Global Series™ Stopper Cylinder
Designed for conveyor applications requiring resistance to side impact loads in a 32 millimeter bore size, the Global Series Stopper Cylinder features heavy-duty mounting, an oversized hard chrome-plated 303 piston rod and special bronze rod bearing with increased surface area.
