The AirTAC Airtac SC40 Standard Cylinder SC40X1200STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 1200mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X1200STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 1200 mm stroke make it a strong candidate for long-reach material transfer or actuation tasks where a compact tie-rod body is preferred.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection without external brackets. The centre trunnion mount (TC suffix, supplied with TCM1 bracket, part code F-SC40TC) allows the cylinder to pivot, accommodating swinging loads. With a 16 mm diameter rod and PT1/4 ports, it operates reliably on standard filtered air.

The 1200 mm stroke combined with centre trunnion mounting allows this cylinder to pivot and sweep parts across a wide conveyor span, ideal for diverters or long pushers.
With sensor-ready position feedback from the built-in magnet, this cylinder can reliably clamp and release large weldments in automated cells, confirming jaw position every cycle.
Provides the long linear motion needed for a palletizer's layer-sweep arm. The trunnion mount absorbs the arc motion, reducing stress on the rod bearing.
For applications requiring slightly less force, stepping down to a 32 mm bore provides 402 N at 0.5 MPa. If higher force is needed, the 50 mm bore delivers 982 N at the same pressure. Always match bore, stroke, port thread (PT), mounting accessory (TC), and magnet option (-S) when replacing an existing unit.
At 1200 mm, this is the maximum standard stroke for the 40 mm bore. Long, unsupported strokes are susceptible to rod bending under side loads. For this stroke length, consider an external guide rail or a guided cylinder if the load is not perfectly axial, to protect the rod bearing and seals from premature wear.
Quick checklist
At the standard operating pressure of 0.5 MPa, this cylinder provides 628 N of push force and 528 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder of the same bore and stroke, so it is not dimensionally interchangeable. You must replace it with another AirTAC SC tie-rod cylinder matching the 40 mm bore, 1200 mm stroke, PT port, TC mount, and -S magnet option.
