The AirTAC Airtac SC40 Standard Cylinder SC40X1770S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1770mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
This SC40X1770S is a double-acting, single-rod pneumatic cylinder with a 40 mm bore and an extra-long 1770 mm non-standard stroke, built with a tie-rod construction that is shorter than an ISO 15552 profile. At 0.5 MPa it delivers 628 N pushing and 528 N pulling force, and at the maximum operating pressure of 0.9 MPa the thrust rises to 1130 N, driven by a 16 mm diameter piston rod.
The suffix -S indicates a built-in magnet around the piston, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position detection. With a standard PT1/4 port, 21 mm adjustable air cushion, and TPU seals rated for -20 to +70 °C, this made-to-order cylinder suits applications demanding very long linear travel with sensor feedback.

Pushes or pulls light components across a wide conveyor gap or between distant stations, with the 1770 mm stroke covering extended transfer distances and the built-in magnet confirming end-of-travel.
Provides the long horizontal axis on a lightweight gantry, where the 16 mm rod must be externally guided to prevent bending during rapid 30-800 mm/s moves.
Raises and lowers small parts bins in a compact vertical lift, using the adjustable air cushion to soften the stop at the 1770 mm extended position without locking the load.
For a 40 mm bore at 0.5 MPa you get 628 N of push force; if your load is lighter and you can accept a smaller profile, stepping down to the 32 mm bore (402 N at 0.5 MPa) may reduce air consumption. For heavier loads, moving up to the 50 mm bore provides 982 N at the same pressure. Because this 1770 mm stroke far exceeds the 1200 mm maximum standard stroke for a 40 mm bore, it is a non-standard, made-to-order length. With any stroke over 300 mm you must manage side loads carefully — a long, unsupported 16 mm rod can bend under lateral force. Always use an external linear guide or a self-guided load carriage; never let the rod bear the full side load. When replacing an existing cylinder, match five points: 40 mm bore, 1770 mm stroke, PT1/4 port thread, the built-in magnet (-S), and your mounting accessory type.
Quick checklist
At 0.5 MPa the theoretical 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. These values assume clean, filtered air and a static load; dynamic forces are slightly lower due to friction.
No, a 1770 mm stroke with a 16 mm rod is highly susceptible to rod buckling and bearing side-load damage. You must support the load with an external linear guide, rod-alignment coupler, or a guided cylinder assembly. The cylinder's rod should only handle axial push-pull forces.
