The AirTAC Airtac SC40 Standard Cylinder SC40X30FA is a genuine double-acting standard air cylinder with a Ø40mm bore and 30mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X30FA is a compact-stroke double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 30 mm stroke suit short linear positioning tasks where a rigid front flange mount is required.
This model includes a front rectangular flange (FA) for secure panel or bulkhead mounting. The 16 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth end-of-stroke deceleration, while the PT1/4 port supplies ample flow for fast cycling.

The 30 mm stroke and front flange mount provide rigid, repeatable clamping force for machining fixtures and assembly jigs.
Delivers a quick 30 mm push to eject small parts from conveyors or sorting gates, with 628 N force at standard line pressure.
The FA front flange allows direct mounting through a panel or bulkhead, ideal for compact machine builds requiring a short linear push.
Choose the SC40X30FA when your application needs a short 30 mm stroke with a rigid front-flange mount. If you require more force, step up to the SC50 bore (982 N push at 0.5 MPa); for a lighter, more compact solution, the SC32 bore (402 N at 0.5 MPa) may suffice. Always match the exact bore, stroke, PT port thread, and FA mounting when replacing an existing cylinder.
For precise replacement, ensure the new unit matches five key points: 40 mm bore, 30 mm stroke, PT1/4 port thread, front flange (FA) mounting accessory (F-SC40FA), and no magnet. The short stroke keeps the rod well-supported, minimizing side-load bending risk.
Quick checklist
At 0.5 MPa the push force is 628 N and pull force is 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable. It directly replaces another AirTAC SC40 cylinder with the same bore, stroke, PT thread, and FA front flange mount.
