The AirTAC Airtac SC50 Standard Cylinder SC50X85FA is a genuine double-acting standard air cylinder with a Ø50mm bore and 85mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X85FA delivers 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a solid mid-range actuator for pressing, clamping, and lifting tasks. Its 20 mm diameter rod and 21 mm adjustable air cushion provide smooth deceleration, while the 150 mm body length A keeps the footprint compact.
This model is configured with a front rectangular flange (FA mount, part F-SC50FA) for secure panel or bulkhead attachment. It uses the standard PT1/4 port thread and TPU seals rated for -20 to +70 °C. As a genuine AirTAC tie-rod cylinder, it offers a proven, serviceable design for demanding industrial environments.

Moves components between conveyor stations with 1374 N of force at 0.7 MPa, ideal for short-stroke push-pull tasks.
Provides consistent 982 N clamping force at 0.5 MPa for CNC fixtures and welding jigs, with a front flange for rigid mounting.
Delivers up to 1767 N at 0.9 MPa for carton compression and label application in automated packaging lines.
Choose the SC50 when your application needs roughly 1000 N of force at standard plant air pressure. If you require more force, stepping up to the SC63 bore provides 1559 N at 0.5 MPa. For a lighter, more compact solution, the SC40 bore delivers 628 N. This 85 mm stroke is a standard length, well within the 1200 mm maximum for this bore size. For a direct replacement, match five key points: 50 mm bore, 85 mm stroke, PT1/4 port thread, FA front flange mounting, and the absence of a magnet.
Quick checklist
At 0.7 MPa (7 bar), the push force is 1374 N. The maximum operating force at 0.9 MPa is 1767 N, and the theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable. Only replace another AirTAC SC or equivalent tie-rod cylinder matching the 50 mm bore, 85 mm stroke, PT1/4 ports, and FA front flange mount.
