The AirTAC Airtac SC40 Standard Cylinder SC40X1400TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 1400mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1400TC is a double-acting single-rod tie-rod cylinder with a 40 mm bore and an extended 1400 mm non-standard stroke, factory-built with a centre trunnion (TC) mount. It delivers 628 N of push force at 0.5 MPa and reaches 1130 N at the 0.9 MPa maximum operating pressure, driven by a 16 mm diameter piston rod with M12x1.25 male threads.
This cylinder uses a PT1/4 port, TPU seals for a -20 to +70 °C range, and an adjustable air cushion (21 mm length) to decelerate the load at stroke end. The body length A is 142 mm, giving a total extended length of approximately 1542 mm. Because the stroke exceeds the 1200 mm maximum standard stroke for bore 40, this is a made-to-order configuration.

The 1400 mm stroke moves lightweight parts or diverters across wide conveyor gaps, using the TC trunnion mount to pivot smoothly as the load path changes.
Operates clamping or positioning jigs in woodworking and assembly fixtures where a long linear stroke is needed but space for a larger bore is limited.
Drives louvre or damper linkages in agricultural ventilation systems, with the centre trunnion allowing the cylinder body to swing as the damper blade rotates.
Choose the SC40 when your application needs roughly 600–1100 N of pneumatic force. If you need more thrust, stepping up to the SC50 delivers 982 N at 0.5 MPa; for a lighter, more compact solution the SC32 provides 402 N. The 1400 mm stroke is non-standard—confirm lead time with your AirTAC distributor.
At this stroke length the unsupported rod is vulnerable to bending under side load; use an external guide rail or a guided-cylinder assembly to protect the rod bearing and seals. For direct replacement, match bore, stroke, PT port thread, TC centre trunnion mount (F-SC40TC bracket included), and the absence of a magnet—this model does not carry the -S magnet option, so sensors require external mounting.
Quick checklist
At 0.7 MPa (7 bar) the SC40 bore produces 879 N of push force and 528 N of pull force on the retract stroke, based on the 40 mm piston and 16 mm rod.
It replaces another AirTAC SC40 tie-rod cylinder of the same 1400 mm stroke, PT1/4 ports, and centre trunnion mount. It is not an ISO 15552 cylinder—the SC body is shorter, so dimensional interchangeability with ISO 15552 profiles is not guaranteed. For guided or side-loaded installations, add an external guide.
