The AirTAC Airtac SC40 Standard Cylinder SC40X700STC 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 SC40X700STC is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 700 mm stroke suit medium-force linear tasks where the cylinder body needs to pivot during operation.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, plus a centre trunnion mount (TC suffix) with the TCM1 bracket (F-SC40TC) for swinging loads. The 16 mm diameter rod, PT1/4 ports, and 21 mm adjustable air cushion provide reliable deceleration. Operating range is -20 to +70 °C with standard TPU seals.

The centre trunnion mount lets the cylinder swing as it opens and closes a material-diverting gate, with magnetic sensors confirming gate position at each end of the 700 mm stroke.
Ideal for welding or assembly jigs that must pivot into place. The 628 N force at 0.5 MPa provides firm clamping, while the trunnion absorbs the arc motion smoothly.
Powers the tilt mechanism on small to medium bin tippers. The long 700 mm stroke gives the leverage needed for a full dump angle, and the magnet sensors ensure safe end-of-travel stops.
Choose the SC40 bore for forces around 628 N at 0.5 MPa; step up to SC50 (982 N) if you need more push, or down to SC32 (402 N) for lighter, more compact tasks. This 700 mm stroke is within the 1200 mm maximum standard stroke for bore 40.
For strokes of 300 mm or longer, watch for side loads on the 16 mm rod. At 700 mm, use an external guide rail or rod-alignment coupler to prevent rod bending and premature bearing wear. When replacing, match bore (40), stroke (700), PT1/4 ports, centre trunnion mount (TC), and the built-in magnet (-S) for sensor compatibility.
Quick checklist
At 0.7 MPa operating pressure, the push force is 879 N. The pull force on the return stroke is 528 N at 0.5 MPa due to the 16 mm rod area.
Yes, if the original is a double-acting SC40 tie-rod cylinder with a 700 mm stroke, PT1/4 ports, centre trunnion (TC) mount, and a magnetic piston. This is not an ISO 15552 cylinder, so it will not directly interchange with profile-cylinder brands unless dimensions are verified.
