The AirTAC Airtac SC40 Standard Cylinder SC40X350SH 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 SC40X350SH is a double-acting pneumatic cylinder delivering 628 N of push force and 528 N of pull force at 0.5 MPa, with a maximum theoretical push of 1130 N at 0.9 MPa. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for the 350 mm stroke, making it well-suited for medium-duty linear tasks.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG, DMSG, or EMSG sensors, enabling precise end-of-stroke detection. The Viton (FKM) seals (-H suffix) shift the operating temperature range to 0–150 °C, making it a strong choice for hot environments where standard TPU seals would degrade.

With Viton seals rated for 0–150 °C, this cylinder is ideal for actuators near ovens, autoclaves, or heated presses where standard seals would fail.
The built-in magnetic piston allows CMSG/DMSG sensors to confirm extend/retract position, perfect for diverting packages on a conveyor line with electronic cycle counting.
Generating 628 N at 0.5 MPa, this 40 mm bore cylinder provides consistent clamping force for CNC fixture doors or welding jigs in a factory setting.
For applications requiring more force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at the same 0.5 MPa pressure. The SC40X350SH uses a 16 mm rod; for strokes over 300 mm, ensure the load is guided externally to prevent rod bending and premature bearing wear from side loads.
When replacing an existing cylinder, match five key points: 40 mm bore, 350 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation. This is a genuine AirTAC tie-rod cylinder, not an ISO 15552 profile unit.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
Yes. The -H suffix denotes Viton (FKM) seals, which have an operating temperature range of 0 to +150 °C. This is significantly higher than the standard TPU seal range of -20 to +70 °C.
