The AirTAC Airtac SC50 Standard Cylinder SC50X75FA is a genuine double-acting standard air cylinder with a Ø50mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X75FA is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 75 mm stroke. At 0.5 MPa it generates 982 N of push force and 825 N on the pull stroke, making it a capable mid-range actuator for clamping and pressing tasks.
This model is factory-configured with an FA front rectangular flange (part F-SC50FA) for rigid panel mounting on the rod side. It uses a 20 mm diameter piston rod with an M16x1.5 male thread, PT1/4 ports, and an adjustable air cushion of 21 mm to decelerate the end-of-stroke travel smoothly.

The FA front flange bolts directly to a fixture plate, allowing the 50 mm bore cylinder to apply 982 N of clamping force on assembly jigs and welding fixtures.
With a 75 mm stroke and 20 mm rod, this actuator reliably extends a stop gate or diverter arm on light-to-medium duty conveyor lines.
Delivers a controlled 1374 N at 0.7 MPa for short-stroke pressing, staking, or crimping operations where front-flange mounting simplifies alignment.
Choose the SC50X75FA when your application needs a compact 50 mm bore with a short 75 mm stroke and a front-flange mounting interface. If you require higher force, stepping up to the 63 mm bore provides 1559 N of push force at the same 0.5 MPa pressure. For lower force and a lighter assembly, the 40 mm bore delivers 628 N.
To ensure a direct replacement, match five key points: the 50 mm bore, 75 mm stroke, PT1/4 port thread, FA front flange mounting, and the standard non-magnetic piston. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, push force increases to 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC50 cylinder with matching bore, stroke, PT ports, and FA front flange mounting.
