The AirTAC Airtac SC40 Standard Cylinder SC40X350SN 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 SC40X350SN is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (879 N at 0.7 MPa). With a 350 mm stroke and a 16 mm diameter piston rod, it suits medium-reach linear actuation tasks where position sensing is required.
This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG reed or solid-state sensors to be clamped directly onto the tie-rod barrel for non-contact end-of-stroke or mid-stroke detection. The NBR seal (-N suffix) provides reliable sealing for standard industrial air, and the PT1/4 port thread ensures straightforward pneumatic connection.

The 350 mm stroke moves components between conveyor lanes, while the built-in magnet triggers CMSG sensors to confirm extend and retract positions for PLC integration.
Delivers 628 N of clamping force at 0.5 MPa for holding workpieces during gluing or fastening. Sensor feedback ensures the clamp is fully engaged before the cycle starts.
Pushes bins or cartons off a gravity roller line with a controlled 350 mm stroke. The NBR seals provide durability in ambient warehouse conditions, and the magnet enables simple position verification.
Choose the SC40 bore for applications needing up to 628 N at 0.5 MPa. If your force requirement is closer to 400 N, the smaller SC32 (402 N at 0.5 MPa) may be a more compact fit. For higher force, step up to the SC50 (982 N at 0.5 MPa). At 350 mm stroke, the rod is extended significantly; avoid direct side loads on the rod end. If lateral forces are present, use an external linear guide or consider a guided cylinder to prevent rod bending and premature seal wear. For a correct replacement, match bore (40 mm), stroke (350 mm), PT port thread, the built-in magnet, and the NBR seal material.
Quick checklist
At 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 reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet, making it fully compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors. These sensors mount directly onto the cylinder's tie-rods to detect the piston position.
