The AirTAC Airtac SC40 Standard Cylinder SC40X830S is a genuine double-acting standard air cylinder with a Ø40mm bore and 830mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X830S is a double-acting single-rod pneumatic cylinder from the AirTAC SC tie-rod series, featuring a 40 mm bore and an 830 mm stroke. At 0.5 MPa operating pressure, it delivers a push force of 628 N and a pull force of 528 N, rising to 1130 N of push thrust at the maximum 0.9 MPa operating pressure.
This model includes the -S suffix, indicating a built-in magnet on the piston, which allows for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for non-contact position sensing. The rod diameter is 16 mm with an M12x1.25 thread, and the total extended body length is approximately 972 mm (142 mm body length A + 830 mm stroke). It uses PT1/4 ports and TPU seals for a standard operating temperature range of -20 to +70 °C.

The 628 N push force at 0.5 MPa is well-suited for diverting medium-weight packages or products on a conveyor line, with the 830 mm stroke providing ample reach across wide belts.
Provides consistent clamping force for jigs and fixtures in automated assembly cells. The built-in magnet enables end-of-stroke confirmation via sensors to ensure cycle safety.
Used to actuate a tipping chute or bin for bulk material dispensing, where the long 830 mm stroke provides the necessary angular rotation and the 528 N pull force retracts the mechanism.
This 40 mm bore cylinder is a mid-force workhorse, ideal when a 32 mm bore (402 N push at 0.5 MPa) is slightly underpowered, but the larger 50 mm bore (982 N) is physically too large. For this 830 mm stroke, ensure the load is guided and side forces are minimal; long, unsupported strokes on a 16 mm rod can be susceptible to bending under side load. If the application involves significant lateral force, an external linear guide or a guided cylinder should be used.
For a direct replacement, match these five points exactly: a 40 mm bore, 830 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensors, and the basic (no bracket) mounting configuration. This cylinder is a genuine AirTAC tie-rod type, not an ISO 15552 profile, and will only interchange dimensionally with another AirTAC SC40 cylinder of the same specifications.
Quick checklist
The theoretical push force is 628 N at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa. The pull force on the retract stroke is 528 N at 0.5 MPa, due to the area reduction from the 16 mm rod.
Yes. The -S suffix in the model code SC40X830S means it has a built-in magnetic piston. You can directly mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors on the barrel's sensor groove to detect piston position without any additional brackets.
