The AirTAC Airtac SC40 Standard Cylinder SC40X100SN is a genuine double-acting standard air cylinder with a Ø40mm bore and 100mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X100SN is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 100 mm standard stroke. At 0.5 MPa it delivers a push force of 628 N and a pull force of 528 N, while at the maximum operating pressure of 0.9 MPa the push force reaches 1130 N. The 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for moderate loads.
This model includes a built-in magnet (suffix S) for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel, simplifying position sensing. The suffix N specifies NBR (nitrile) seals, suitable for standard temperature ranges. The body length A is 142 mm, giving a total extended length of approximately 242 mm. Ports are threaded PT1/4, and the rod thread is M12x1.25.

The 40 mm bore provides crisp actuation for diverting small cartons on a conveyor. The built-in magnet allows end-of-stroke sensors to confirm each cycle, integrating easily with PLC-controlled packaging machinery.
With 628 N of force at standard line pressure, this cylinder is well-suited for clamping light to medium workpieces in CNC fixtures. The NBR seals are compatible with common workshop air supplies.
The 100 mm stroke and magnetic piston make it ideal for repetitive linear motion in test stands. Sensors provide accurate position data for data logging, while the tie-rod design allows for straightforward maintenance.
Choose the SC40X100SN when your application needs a 40 mm bore with sensor feedback. If higher force is required, stepping up to the 50 mm bore provides 982 N of push force at 0.5 MPa. For lighter, more compact needs, the 32 mm bore delivers 402 N. As a 100 mm stroke is well within the 1200 mm maximum standard stroke for this bore, it is a standard catalog item.
To ensure a correct replacement, match five key points: bore (40 mm), stroke (100 mm), port thread (PT), the built-in magnet (-S) for sensor compatibility, and the mounting style (this is a basic model, so no additional brackets are included). Always verify the tie-rod dimensions against the original AirTAC SC cylinder.
Quick checklist
At 0.7 MPa operating pressure, the push force is 879 N. The theoretical maximum force at 1.0 MPa is 128 kgf, but the recommended operating range is 0.15 to 1.0 MPa.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. Mounting accessories are specific to the SC series, using codes like F-SC40LB for a foot mount. It is not dimensionally interchangeable with ISO 15552 cylinders.
