The AirTAC Airtac SC40 Standard Cylinder SC40X700TC 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 SC40X700TC is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore houses a 16 mm diameter piston rod with M12x1.25 threads, and the 700 mm stroke suits medium-reach clamping, pressing, and material-transfer tasks.
This model ships with a factory-fitted centre trunnion (TC) mount and the TCM1 bracket, allowing the cylinder to pivot as the rod extends and retracts. The adjustable air cushion (21 mm length) decelerates the piston near stroke end to reduce impact, while the PT1/4 port accepts standard pneumatic fittings. Total extended body length is approximately 842 mm.

The 700 mm stroke and centre trunnion pivot let this cylinder swing a diverter gate across a conveyor line, sorting packages by lane with smooth, cushioned end-of-stroke deceleration.
With 628 N of force at 0.5 MPa, the SC40X700TC applies steady clamping pressure on medium-sized workpieces in welding or assembly fixtures, where the trunnion mount allows the cylinder body to self-align.
The pivoting TC mount makes this cylinder ideal for tilting bins or hoppers. The 700 mm stroke provides the reach needed to rotate a container for controlled material discharge.
The SC40 bore sits between the compact SC32 (402 N at 0.5 MPa) and the larger SC50 (982 N at 0.5 MPa). If your load requires more than 628 N of push force at plant pressure, step up to the SC50; if space is tight and force is sufficient, the SC32 may fit. At 700 mm stroke, ensure the rod is not subjected to side load—long, unsupported rods can bend under off-axis forces. Use an external linear guide or switch to a guided cylinder if side loading is present.
For drop-in replacement, match five points: bore (40 mm), stroke (700 mm), port thread (PT1/4), centre trunnion mounting (TC with TCM1 bracket, part F-SC40TC), and confirm whether a magnet is needed (this model has no built-in magnet).
Quick checklist
At 0.5 MPa the cylinder produces 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, push force rises to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder of the same bore and stroke, so mounting dimensions and overall length differ. Only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, and TC trunnion mount.
