The AirTAC Airtac SC40 Standard Cylinder SC40X423 is a genuine double-acting standard air cylinder with a Ø40mm bore and 423mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X423 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 423 mm stroke. At 0.5 MPa it produces 628 N extending thrust and 528 N retracting force, scaling to 1130 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator.
This model features a 16 mm diameter piston rod with M12x1.25 threads and PT1/4 ports for standard pneumatic connections. The body length A is 142 mm, yielding a total extended length of approximately 565 mm. Its adjustable air cushion (21 mm length) decelerates the piston smoothly at stroke ends, and the standard TPU seals suit operating temperatures from -20 to +70 °C.

Provides the 628 N push force needed to raise and lower stop gates on package conveyor lines, controlling carton flow with reliable double-acting control.
Delivers consistent clamping pressure for woodworking or light metal fabrication jigs, with the 423 mm stroke accommodating varied workpiece sizes.
Operates diverter flaps on grading or sorting tables, handling frequent cycling in dusty environments when supplied with properly filtered air.
For applications needing slightly less force, the 32 mm bore SC32 series offers 402 N at 0.5 MPa in a more compact envelope. If your load demands higher thrust, stepping up to the 50 mm bore SC50 provides 982 N at the same pressure. Always match replacement cylinders on five key points: bore (40 mm), stroke (423 mm), port thread (PT1/4), mounting style, and magnet option.
With a 423 mm stroke, the 16 mm rod is susceptible to bending under side loads. Install an external linear guide or ensure the load is purely axial to prevent rod bearing damage and seal wear. For non-axial loads, consider a guided cylinder assembly.
Quick checklist
At 0.7 MPa operating pressure, the theoretical extending force is 879 N. The retracting force at the same pressure is lower due to the rod area, delivering 528 N at 0.5 MPa.
Yes, the basic SC40X423 can be ordered with the TC suffix (SC40X423TC) which includes a centre trunnion and TCM1 bracket, or you can retrofit the F-SC40TC trunnion kit. The standard model comes without mounting accessories.
