The AirTAC SC50 Standard Cylinder SC50X500FA is a genuine double-acting standard air cylinder with a Ø50mm bore and 500mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X500FA 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 500 mm stroke, it is equipped with a 20 mm diameter piston rod and an M16x1.5 rod thread for secure tooling attachment.
This configuration includes a front rectangular flange (FA) for rigid panel or end-face mounting, part code F-SC50FA. The cylinder features an adjustable pneumatic cushion (21 mm length) to decelerate the piston smoothly at stroke end, and uses standard PT1/4 ports with TPU seals for operation in ambient temperatures from -20 to +70 °C.

The 500 mm stroke and front flange mount provide a rigid, extended reach for stopping or diverting packages on wide conveyor lines, with 982 N of force at standard shop air.
Front-flange mounting allows the cylinder body to be securely fixed inside a machine frame, using the full 500 mm stroke to actuate heavy-duty clamps on welding or assembly jigs.
Delivers a long, linear push stroke to separate and eject pallets from a stack, leveraging the SC50's 1767 N maximum force at 0.9 MPa for reliable operation.
For applications requiring higher force, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa. If space is a constraint and lower force is acceptable, the 40 mm bore SC40 series offers 628 N at the same pressure. This cylinder uses a front flange mount (FA), so ensure your mounting surface is flat and rigid to prevent misalignment.
At a 500 mm stroke, the 20 mm rod is subject to bending moments under side load. For non-axial loads, install an external linear guide or consider a guided cylinder to protect the rod bearing and seals. For a direct replacement, match the 50 mm bore, 500 mm stroke, PT1/4 port thread, FA front flange mounting, and the absence of a magnet.
Quick checklist
At 0.5 MPa, the cylinder provides 982 N of push force and 825 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
No. The SC50X500FA is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost or the valve is centered, the piston can drift. A pilot-operated check valve or external rod lock is required for static load holding.
