The AirTAC Airtac SC40 Standard Cylinder SC40X700SLBN is a genuine double-acting standard air cylinder with a Ø40mm bore and 700mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X700SLBN is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. Its 700 mm stroke, combined with a 16 mm diameter piston rod and a 21 mm adjustable air cushion, makes it a reliable workhorse for medium-length linear movements in automation.
This specific model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, LB-style axial foot mounts (F-SC40LB) for secure surface installation, and NBR seals (-N) for standard temperature operation. The PT1/4 port thread ensures straightforward pneumatic connections.

The 700 mm stroke and 628 N force at 0.5 MPa are ideal for pushing boxes or totes off a conveyor line onto a gravity roller spur, with the LB foot mount providing a stable base.
The built-in magnet allows sensors to confirm full retraction and extension, making this cylinder suitable for clamping and positioning parts in a robotic welding cell where NBR seals are compatible.
With 1130 N of force at 0.9 MPa, this cylinder can reliably transfer a layer of empty containers onto a pallet stacker, with the long stroke bridging the gap between the infeed and the pallet.
For applications requiring more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N of push force at 0.5 MPa. If a shorter, more compact cylinder is sufficient, the 32 mm bore SC32 series offers 402 N at the same pressure. At a 700 mm stroke, ensure the load is guided to prevent excessive side load on the 16 mm rod bearing; an external guide rail or a guided cylinder configuration is strongly recommended to prevent rod bending and premature seal wear. For direct replacement, match the 40 mm bore, 700 mm stroke, PT port thread, LB foot mount, and the built-in magnet for sensor compatibility.
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. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC tie-rod cylinder with the same 40 mm bore, 700 mm stroke, PT ports, LB foot mount, and built-in magnet.
