The AirTAC Airtac SC40 Standard Cylinder SC40X1150S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1150mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X1150S is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 1150 mm stroke suit long-reach linear tasks, with a 16 mm diameter piston rod providing robust column strength.
This model includes the -S suffix for a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to clamp directly onto the tie-rod barrel for contactless position feedback. The adjustable air cushion decelerates the piston over 21 mm at each end, reducing end-cap impact at speeds up to 800 mm/s.

Moves components across wide conveyor gaps or between parallel lines, with magnetic sensors confirming end-of-stroke positions.
Extends a dispensing head over a large panel; the 16 mm rod resists bending under the tool weight, and sensor feedback controls the deposit length.
Positions the film carriage vertically over a 1150 mm travel, using the adjustable cushion to soften stops at high cycling speeds.
For higher force, step up to the 50 mm bore SC50 series (982 N at 0.5 MPa). For lighter, more compact needs, the 32 mm bore SC32 series provides 402 N. At 1150 mm stroke, the rod is near the maximum standard length for this bore (1200 mm); ensure the load is guided externally or use a guided cylinder to prevent rod bearing side-load damage.
To replace an existing unit, match five points: 40 mm bore, 1150 mm stroke, PT port thread, basic mounting, and the -S magnet option for sensor compatibility.
Quick checklist
At 0.5 MPa, push force is 628 N and pull force is 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston. You can clamp compatible CMSG, DMSG, or EMSG sensors directly onto the barrel to detect piston position without external brackets.
