The AirTAC Airtac SC40 Standard Cylinder SC40X890S is a genuine double-acting standard air cylinder with a Ø40mm bore and 890mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X890S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with an 890 mm stroke. At 0.5 MPa it produces 628 N extending and 528 N retracting, while the maximum operating thrust reaches 1130 N at 0.9 MPa, driven by a 16 mm diameter piston rod.
This model includes the -S suffix, indicating a built-in magnet embedded in the piston. The magnet allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position sensing. The cylinder body length A is 142 mm, giving a total extended length of approximately 1032 mm, and it features an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly.

The 890 mm stroke moves components between distant conveyor stations. The built-in magnet enables end-of-stroke confirmation via barrel-mounted sensors.
Directs products down different chutes in material handling lines. The 628 N push force at standard plant pressure is sufficient for medium-weight diverter flaps.
Extends a stop blade to control pallet flow in gravity roller systems. The adjustable cushion absorbs impact energy at full extension, reducing noise and vibration.
For applications needing slightly less force, the 32 mm bore SC32 series provides 402 N push at 0.5 MPa. If higher force is required, stepping up to the 50 mm bore SC50 delivers 982 N at the same pressure. Always match five key points when replacing an existing cylinder: bore (40 mm), stroke (890 mm), PT port thread, basic mounting configuration, and the presence of the magnet for sensor compatibility.
With an 890 mm stroke, the 16 mm rod is relatively long. Side loads or off-centre mounting can cause rod deflection and accelerated bearing wear. For this stroke length, consider pairing the cylinder with an external linear guide or switching to a guided cylinder assembly if the load is not perfectly axial.
Quick checklist
At 0.5 MPa (approx. 73 psi), the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the extending thrust increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes. The -S suffix in SC40X890S means the piston carries a built-in magnet. You can clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
