The AirTAC SC50 Standard Cylinder SC50X900SFA is a genuine double-acting standard air cylinder with a Ø50mm bore and 900mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X900SFA is a double-acting AirTAC SC tie-rod cylinder delivering 1374 N of push force at 0.7 MPa, ideal for medium-duty linear tasks. Its 900 mm stroke is paired with a 20 mm diameter piston rod and PT1/4 ports, providing a solid balance of reach and structural rigidity.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The front rectangular flange (FA) allows secure panel mounting, and the adjustable air cushion at each end decelerates the piston smoothly over a 21 mm cushion length.

The 900 mm stroke and front flange mount suit long-reach part transfer systems on packaging lines, where sensor feedback confirms each completed cycle.
Applies 1374 N at 0.7 MPa to push heavy components off a conveyor. The adjustable cushion manages impact at the end of the long 900 mm travel.
Directs products into different chutes in a sorting system. The built-in magnet sensor verifies the diverter gate position at each stroke end.
Select the SC50X900SFA when your application requires a 900 mm stroke with a push force of 982 N at 0.5 MPa. If you need higher force, consider stepping up to the SC63 series, which provides 1559 N at the same pressure. For lower force requirements, the SC40 series offers 628 N.
At a 900 mm stroke, the 20 mm rod is susceptible to bending under side loads. For this extended reach, evaluate an external guide rail or a guided cylinder to protect the rod and bearing from misalignment. When replacing this cylinder, match the 50 mm bore, 900 mm stroke, PT1/4 ports, front flange mount (FA), and the built-in magnet sensor option.
Quick checklist
At the maximum operating pressure of 0.9 MPa, this cylinder provides 1767 N of push force. At the standard 0.7 MPa, it delivers 1374 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder, so it is not dimensionally interchangeable. It directly replaces another AirTAC SC50 cylinder with matching bore, stroke, PT ports, FA front flange mount, and the -S magnet option.
