The AirTAC Airtac SC40 Standard Cylinder SC40X380 is a genuine double-acting standard air cylinder with a Ø40mm bore and 380mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X380 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 380 mm stroke. At 0.5 MPa it provides 628 N of push force and 528 N of pull force, rising to 1130 N at 0.9 MPa, making it a capable mid-range actuator for linear motion tasks.
The 16 mm diameter piston rod and 21 mm adjustable air cushion at each end ensure smooth deceleration. With a body length A of 142 mm, the total extended length is approximately 522 mm. PT1/4 ports and an M12x1.25 rod thread are standard, and the cylinder operates on filtered air from 0.15 to 1.0 MPa.

Moves components between conveyor lanes or workstations with a controlled 380 mm stroke, using the 628 N push force at standard line pressure.
Applies consistent clamping force up to 1130 N at 0.9 MPa for holding workpieces during machining or assembly operations.
Ejects totes or cartons from a gravity roller conveyor onto a takeaway line, leveraging the full 380 mm travel.
For applications needing more force, stepping up to the 50 mm bore SC50 series delivers 982 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 32 mm bore SC32 provides 402 N at the same pressure. Always match bore, stroke, port thread (PT), and mounting when replacing an existing unit.
At 380 mm of stroke, the unsupported rod length increases the risk of bending under side loads. Fit an external linear guide or specify a guided cylinder if the load is not perfectly axial, to protect the rod bearing and extend seal life. A five-point replacement match covers bore, stroke, port thread, mounting accessory, and magnet option.
Quick checklist
At 0.5 MPa the push force is 628 N and the pull force is 528 N. At 0.7 MPa push rises to 879 N, and at the maximum operating pressure of 0.9 MPa it reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes, provided the old cylinder is also a tie-rod design with matching 40 mm bore, 380 mm stroke, PT1/4 ports, and the same mounting style. The SC series is shorter than an ISO 15552 cylinder, so it is not a direct dimensional interchange for ISO 15552 profiles. Check rod thread (M12x1.25) and cushion length (21 mm) against your existing unit.
