The AirTAC Airtac SC40 Standard Cylinder SC40X760STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 760mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X760STC is a double-acting single-rod pneumatic cylinder with a 40 mm bore and 760 mm stroke. It generates 628 N of push force and 528 N of pull force when operated at 0.5 MPa, making it a capable mid-range actuator for general industrial automation.
This model features a 16 mm diameter piston rod and a compact 142 mm body length, resulting in a total extended length of approximately 902 mm. It includes a built-in magnet for mounting CMSG/DMSG/EMSG sensors and a TC centre trunnion mount with the TCM1 bracket for pivoting applications. The adjustable air cushion at each end is 21 mm long, ensuring smooth deceleration.

The 628 N push force at 0.5 MPa and mid-range stroke reliably actuates diverter gates on packaging and sortation conveyors, directing products between lanes.
Ideal for welding or assembly fixtures where a 760 mm stroke is needed to move a clamp into position. The built-in magnet allows for easy end-of-stroke sensing to confirm the part is secured.
Provides robust linear motion for chute controls or bin gates on harvesters and planters. The TPU seals and trunnion mount handle dusty environments and the pivoting motion required by the linkage.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at the same 0.5 MPa pressure. If a shorter, more compact footprint is acceptable, the 32 mm bore SC32 delivers 402 N. This 760 mm stroke is within the 1200 mm maximum standard stroke for the 40 mm bore. For any stroke over 300 mm, be mindful of side loads; the 16 mm rod can bend under lateral force. Use an external guide rail or switch to a guided cylinder if the load is not perfectly axial. To ensure a correct replacement, match five key points: 40 mm bore, 760 mm stroke, PT port thread, TC centre trunnion mounting, and the -S magnet option for sensor compatibility.
Quick checklist
At the standard operating pressure of 0.5 MPa, this 40 mm bore cylinder produces 628 Newtons of push force and 528 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
To guarantee a drop-in replacement, you must match the AirTAC SC series tie-rod design and confirm five specifications: a 40 mm bore, a 760 mm stroke, a PT port thread, a TC centre trunnion mount with the TCM1 bracket, and the -S suffix for a built-in sensor magnet. This cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders.
