The AirTAC Airtac SC40 Standard Cylinder SC40X1620S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1620mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1620S is a double-acting tie-rod cylinder with a 40 mm bore and an extended 1620 mm non-standard stroke, factory-built to order. It delivers 628 N of push force at 0.5 MPa and 1130 N at 0.9 MPa, driven by a 16 mm diameter piston rod with M12x1.25 male threads.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. The 21 mm adjustable air cushion at each end decelerates the piston smoothly, and the PT1/4 port threads match standard pneumatic fittings. Note that at this stroke length the unsupported rod requires an external guide or guided-cylinder arrangement to prevent bending under side load.

Moves components across wide conveyor gaps or between distant stations with a 1620 mm stroke, while the magnetic piston enables end-of-stroke confirmation via barrel-mounted sensors.
Pushes or pulls tooling, gates, or diverters in packaging and assembly lines where a long linear stroke and sensor feedback are required for cycle sequencing.
Operates tall or deep sorting chute doors in logistics systems, using the -S magnet for open/closed position verification without adding external flag sensors.
Choose the SC40X1620S when your application needs a 40 mm bore with a long 1620 mm reach and integrated magnetic sensing. If you need more force, step up to the 50 mm bore (982 N at 0.5 MPa); for a lighter, more compact design, the 32 mm bore provides 402 N. Because the stroke exceeds 300 mm, side-loading the exposed rod can cause bearing wear or rod buckling—always use an external linear guide or a guided cylinder if the load is not perfectly axial. For direct replacement, match bore, stroke, PT1/4 ports, the built-in magnet, 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, the push force rises to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Match five points: 40 mm bore, 1620 mm stroke, PT1/4 port threads, the built-in magnet (-S) for sensor mounting, and the basic (no accessory) mounting style. Because 1620 mm exceeds the 1200 mm max standard stroke for bore 40, this is a non-standard made-to-order length—confirm the extended body dimension (A=142 mm + stroke) fits your space.
