The AirTAC Airtac SC40 Standard Cylinder SC40X1130LB is a genuine double-acting standard air cylinder with a Ø40mm bore and 1130mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X1130LB is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 1130 mm stroke is within the 1200 mm maximum standard stroke for the 40 mm bore, making it a standard-length option for long-reach linear tasks.
This model includes the LB foot mounting (F-SC40LB) for secure surface installation and features a 16 mm diameter piston rod with M12x1.25 threads. The adjustable air cushion at each end is 21 mm long, effectively decelerating the piston to reduce end-of-stroke impact.

Pushes or pulls lightweight components across a wide conveyor gap, ideal for sorting or diverting operations in packaging lines.
Provides the extended linear stroke needed for applying adhesives or sealants along lengthy seams in furniture or automotive parts.
Operates louvers, hopper doors, or ventilation gates in agricultural machinery, leveraging the long stroke for full open/close cycles.
For higher force requirements, consider stepping up to the 50 mm bore (SC50 series), which provides 982 N at 0.5 MPa. For lighter, more compact needs, the 32 mm bore offers 402 N. When using a 1130 mm stroke, ensure the rod is not subjected to side loads; external linear guides are recommended to prevent rod bending and premature seal wear. To replace an existing cylinder, match the 40 mm bore, 1130 mm stroke, PT1/4 port thread, LB foot mounting, and confirm if a magnet is needed.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N.
For a stroke of 1130 mm, side loading is a critical concern. Always align the load along the rod's axis. If any radial force is present, install an external guide rail or rod support to absorb the side load and protect the rod bearings and seals.
