The AirTAC SC50 Standard Cylinder SC50X700SFA is a genuine double-acting standard air cylinder with a Ø50mm bore and 700mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X700SFA is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 700 mm stroke, this model is equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors, providing reliable end-of-stroke detection without external brackets.
This configuration includes a front rectangular flange (FA) for secure panel or bulkhead mounting, using accessory part F-SC50FA. The 20 mm diameter piston rod and PT1/4 port threads handle standard industrial air supply, while the adjustable pneumatic cushion at each end decelerates the 700 mm stroke smoothly. The total body length is 150 mm, making the extended length approximately 850 mm.

The 700 mm stroke and front flange mount are ideal for actuating diverter gates on conveyor systems, with the built-in magnet confirming gate position.
Delivers a consistent 982 N push at 0.5 MPa to index material into a stamping press, with sensor feedback ensuring the full 700 mm feed cycle is complete.
Provides a 700 mm linear reach for clamping large assemblies in a welding fixture, where the front flange allows rigid mounting to the fixture plate.
Select the SC50 bore when your application requires around 982 N of force at standard 0.5 MPa shop air. If you need more force, stepping up to the SC63 bore provides 1559 N at the same pressure. For a 700 mm stroke, the 20 mm rod is robust, but always check for side loads; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear on long-stroke applications.
To ensure a correct replacement, match five key points: bore (50 mm), stroke (700 mm), port thread (PT1/4), front flange mounting (FA), and the built-in magnet (-S). This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
Quick checklist
At 0.5 MPa, the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. These values are for a double-acting cylinder with a 20 mm rod.
No. The SC50X700SFA is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston will drift. For load-holding, you must add a pilot-operated check valve or an external mechanical rod brake.
