1. Impact-resistant design: Features a thickened piston rod; heavy-duty models include a built-in, adjustable hydraulic shock absorber to absorb the inertial impact of pallets, thereby protecting the cylinder body and tooling.
2. Optional rod ends: Roller type suitable for assembly lines; lever-roller type features a self-locking mechanism to prevent workpiece rebound.
3. Flexible installation: Bottom flange mounting with adjustable stopping height; cylinder body equipped with mounting slots for magnetic switches on all sides.

Direct Factory PricingStopper cylinders—also known as stop cylinders or limit cylinders—are specialized, low-profile,
heavy-duty cylinders designed for use on assembly line conveyors.
They are used to block or release workpiece pallets and material carriers, enabling precise, fixed-point stopping at automated conveyor stations.
1. A thickened piston rod effectively enhances the cylinder’s impact resistance;
2. Heavy-duty stopper cylinders feature hydraulic shock absorbers (fixed or adjustable) to reliably absorb impact energy;
3. Lever-type roller stopper cylinders are equipped with a self-locking mechanism to prevent the rocker arm from rebounding and pushing back against the stopped object;
4. A wide range of stopper cylinder series and specifications is available for customers to choose from.
