The AirTAC Airtac SC40 Standard Cylinder SC40X800S is a genuine double-acting standard air cylinder with a Ø40mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X800S is a double-acting tie-rod cylinder with a 40 mm bore and an 800 mm stroke, factory-equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors. At 0.5 MPa air pressure it generates 628 N extending force and 528 N retracting force, rising to 1130 N push at the 0.9 MPa maximum operating pressure.
This model uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The adjustable air cushion at each end absorbs 21 mm of stroke-end energy, and the aluminium barrel body length A is 142 mm. The -S suffix magnet lets you clamp reed or solid-state switches onto the barrel without extra brackets, simplifying position feedback for automated sequences.

The 800 mm stroke moves components between distant conveyor lanes or workstations. The built-in magnet confirms end-of-stroke with CMSG sensors, ensuring reliable handshaking with pick-and-place controls.
Delivers a steady 628 N push at 0.5 MPa to drive adhesive dispensing heads along an 800 mm linear path. Sensor feedback from the -S magnet verifies retraction before the next bead is laid.
Operates a tall diverter gate in a gravity chute system. The 16 mm rod and 21 mm cushion manage the repetitive impact, while the magnetic piston signals open/closed status to the warehouse PLC.
Choose the SC40 bore when your application needs between 500 N and 900 N of push force at standard shop air; if you need more, step up to the SC50 which delivers 982 N at 0.5 MPa, or down to the SC32 (402 N) for lighter, faster cycling. For this 800 mm stroke, ensure the rod is not subjected to side loading—long unsupported rods can bend under lateral force. Use an external linear guide or a guided cylinder if the load path is not perfectly axial.
To replace an existing cylinder, match five points: 40 mm bore, 800 mm stroke, PT1/4 ports, the built-in magnet (-S) for sensor compatibility, and your current mounting accessory (this unit is basic mount, so order LB, FA, FB, CA, CB, or TC brackets separately if needed).
Quick checklist
At 0.7 MPa (7 bar) the SC40 bore generates 879 N of extending force and 738 N of retracting force. The maximum operating pressure is 1.0 MPa, giving 1130 N push.
Yes. The -S suffix means a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the barrel tie-rods to detect piston position without extra mounting hardware.
