The AirTAC Airtac SC40 Standard Cylinder SC40X350N is a genuine double-acting standard air cylinder with a Ø40mm bore and 350mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X350N is a double-acting pneumatic cylinder with a 40 mm bore and 350 mm stroke, fitted with NBR (nitrile) seals for reliable operation in standard temperature environments. Its 16 mm diameter piston rod and PT1/4 port connection make it a versatile actuator for medium-duty linear motion tasks.
At 0.5 MPa air pressure, this cylinder produces a theoretical push force of 628 N and a pull force of 528 N, rising to 1130 N push at 0.9 MPa. The body length A measures 142 mm, giving a total extended length of approximately 492 mm. The adjustable air cushion at both ends, with a 21 mm cushion length, helps decelerate the piston smoothly, reducing impact and noise.

Moves lightweight parts between conveyor sections with a 350 mm reach, using the 628 N push force at standard line pressure.
Applies consistent clamping force in woodworking or light metalworking jigs, where the NBR seals handle workshop air supplies.
Pushes small bins or totes off a gravity roller lane, using the full 350 mm stroke to clear the lane completely.
Selecting the SC40X350N means matching a 40 mm bore tie-rod cylinder with a 350 mm stroke and PT ports. If your force requirement is slightly lower, the SC32 series provides 402 N push at 0.5 MPa; for a step up in power, the SC50 delivers 982 N. For strokes of 300 mm or more, consider the rod bearing load—a 16 mm rod extended to 350 mm can experience bending under significant side force. Use an external guide or a guided cylinder if the load is not purely axial. When replacing, match bore, stroke, port thread (PT), NBR seals, and ensure the mounting style is basic (no bracket).
Quick checklist
At 0.5 MPa (5 bar), the push force is 628 N and pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. These are theoretical values for a double-acting cylinder.
No, the SC series is a tie-rod cylinder and is shorter in overall length than a standard ISO 15552 profile cylinder. For a drop-in replacement, match the 40 mm bore, 350 mm stroke, PT1/4 ports, and basic mounting configuration exactly.
