The AirTAC Airtac SC50 Standard Cylinder SC50X70FA is a genuine double-acting standard air cylinder with a Ø50mm bore and 70mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X70FA is a 50 mm bore double-acting pneumatic cylinder with a 70 mm stroke, supplied with a front rectangular flange (FA) for rigid panel mounting. It generates 982 N of push force at 0.5 MPa and 1767 N at 0.9 MPa, making it a capable mid-range actuator for pressing, clamping, and lifting tasks.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion decelerates the piston over the final 21 mm of travel, reducing end-of-stroke impact. The front flange (F-SC50FA) bolts directly to a machine face, keeping the cylinder body cantilevered for easy access to ports and sensors.

The 70 mm stroke and front flange mount make it easy to install as a compact part stop on conveyor lines, reliably halting totes or pallets with 982 N of force.
Direct panel mounting via the FA flange provides a stable base for clamping workpieces in CNC or welding fixtures, where the 20 mm rod resists bending under repeated cycles.
Delivering up to 1767 N at 0.9 MPa, this cylinder suits light arbor presses and assembly tools for inserting bearings, bushings, or pins with controlled force.
Choose the SC50 when you need around 1000 N of force at standard shop air. If your load is lighter, stepping down to a 40 mm bore (628 N at 0.5 MPa) saves space and air consumption. For heavier loads, the 63 mm bore delivers 1559 N at the same pressure.
To replace an existing cylinder, match five points: 50 mm bore, 70 mm stroke, PT1/4 port thread, front flange FA mounting, and the absence of a magnet. This is a tie-rod cylinder with a shorter body than ISO 15552 equivalents; always verify the body length A of 150 mm plus the 70 mm stroke fits your machine envelope.
Quick checklist
At 0.5 MPa, push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No, the FA front flange is designed for fixed, rigid mounting to a flat surface. If your application requires the cylinder to pivot, consider the same bore and stroke with a rear clevis (CA or CB) or centre trunnion (TC) mount instead.
