The AirTAC Airtac SC40 Standard Cylinder SC40X880S is a genuine double-acting standard air cylinder with a Ø40mm bore and 880mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X880S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore houses a 16 mm diameter piston rod with M12x1.25 male threads, and the 880 mm stroke suits medium-reach clamping, lifting, or material-transfer tasks.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for end-of-stroke detection. The adjustable air cushion (21 mm length) decelerates the piston smoothly, and the PT1/4 port accepts standard pneumatic fittings. Total body length A is 142 mm, giving an extended length of approximately 1022 mm.

Moves components between conveyor lanes or indexing stations with an 880 mm reach, using the built-in magnet for precise end-of-stroke sensor feedback.
Applies consistent 628 N clamping force at 0.5 MPa on assembly jigs; the sensor confirms the jaw is fully closed before the cycle continues.
Drives a diverter gate in a packaging or logistics line, with the long 880 mm stroke providing ample travel for wide chute openings.
Choose the SC40 bore when your application needs between roughly 400 and 630 N of push force at standard shop air; stepping up to the SC50 delivers 982 N at 0.5 MPa if your load grows. For this 880 mm stroke, be mindful of side loading—long, unsupported rods can bend under off-axis forces, so consider an external linear guide or switch to a guided cylinder if the load is not perfectly axial. When replacing an existing cylinder, match five points: 40 mm bore, 880 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no-bracket) mounting configuration.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical force at 1.0 MPa is 128 kgf.
Yes. The -S suffix means a magnet is built into the piston, so you can clamp CMSG, DMSG, or EMSG reed/solid-state sensors directly onto the barrel to detect piston position without external brackets.
