The AirTAC Airtac SC40 Standard Cylinder SC40X200STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 200mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X200STC is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 200 mm stroke. This model generates a push force of 628 N at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa, driven by a 16 mm diameter piston rod.
This specific configuration includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (-TC suffix) supplied with the TCM1 bracket (F-SC40TC). The cylinder body length is 142 mm, and it features an adjustable air cushion of 21 mm to decelerate the piston smoothly at stroke end.

The 200 mm stroke and centre trunnion mount allow this cylinder to pivot and actuate diverter gates on conveyor lines, with the built-in magnet providing end-of-stroke position feedback to the PLC.
Delivers a controlled 628 N clamping force at 0.5 MPa, ideal for holding parts during welding or assembly. The adjustable cushion prevents impact vibration that could misalign precision fixtures.
The tie-rod design and 16 mm rod provide robust, repeatable push strokes for case packing. The trunnion mount absorbs the pivoting motion, reducing side-load stress on the piston seals.
Select the SC40 bore for applications needing up to 628 N of push force at standard plant pressure. If your load requires more force, step up to the SC50, which provides 982 N at 0.5 MPa. For a lighter, more compact solution, the SC32 delivers 402 N.
This 200 mm stroke model operates well within the 1200 mm maximum standard stroke for the 40 bore. When replacing an existing cylinder, ensure a 5-point match: 40 mm bore, 200 mm stroke, PT port thread, centre trunnion mounting (TC), and the presence of a magnet for sensors (-S). For strokes over 300 mm, always assess side-loading on the 16 mm rod and consider an external guide to prevent rod bearing damage.
Quick checklist
At 0.5 MPa (standard shop air), the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor groove to detect piston position without any additional brackets.
