The AirTAC Airtac SC40 Standard Cylinder SC40X350SLB 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 SC40X350SLB 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 350 mm stroke suit medium-duty linear tasks where a compact tie-rod body is preferred.
This model includes a built-in magnet (-S) for CMSG/DMSG/EMSG sensors and is supplied with LB axial foot mounts (F-SC40LB) for secure surface installation. The 16 mm rod and 21 mm adjustable air cushion provide smooth deceleration, while the PT1/4 port ensures straightforward pneumatic connection.

Operates diverter gates on medium-speed packaging lines. The 350 mm stroke provides sufficient travel for product sorting, while the LB mount keeps the cylinder rigidly fixed to the frame.
Delivers 628 N of clamping force at 0.5 MPa for woodworking or light metalworking jigs. The magnetic piston allows sensor-based confirmation of clamp position before the cycle starts.
Opens and closes discharge doors on small agricultural hoppers or seed dispensers. The tie-rod construction handles dusty environments, and the adjustable cushion softens the door impact at stroke end.
Choose the SC40 when your application needs roughly 628 N at standard line pressure; step up to the SC50 bore for 982 N push if the load margin is tight. For this 350 mm stroke, ensure the rod is not subjected to significant side load—an external guide or guided cylinder is recommended to protect the rod bearing from bending moments.
When replacing an existing cylinder, match five points: 40 mm bore, 350 mm stroke, PT1/4 port thread, LB foot mounting (F-SC40LB), and the -S magnet for sensor compatibility. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profiles.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston, so AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors can be clamped directly onto the barrel to detect end-of-stroke or intermediate positions.
