The AirTAC SC50 Standard Cylinder SC50X720TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 720mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X720TC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 720 mm stroke and centre trunnion mount make it ideal for applications requiring the cylinder body to pivot during operation, such as clamping or swivelling material-handling arms.
This model features a 20 mm piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at each end of the stroke, reducing impact and noise. The TC suffix denotes the centre trunnion mounting style, supplied complete with the TCM1 bracket (order code F-SC50TC).

Pivoting actuator for diverting or lifting parts on a conveyor line. The 720 mm stroke reaches across wide belts, and the TC mount allows the cylinder body to swing clear during retraction.
Operates a pivoting clamp arm in a weld cell. The trunnion mount absorbs misalignment, and the 982 N force securely holds the workpiece during assembly.
Actuates a diverter gate on a grain chute or hopper. The cylinder pivots on its trunnions as the gate opens and closes, providing reliable force in dusty agricultural environments.
The SC50X720TC suits medium-force tasks. If your application demands higher force, consider stepping up to the 63 mm bore (1559 N at 0.5 MPa). For a lighter, more compact solution, the 40 mm bore provides 628 N. Always match replacement cylinders across five key points: 50 mm bore, 720 mm stroke, PT port thread, centre trunnion (TC) mount, and the absence of a magnet.
At 720 mm stroke, the extended rod is subject to bending under side loads. Ensure the load is guided externally or use a rigid alignment to prevent rod bearing damage and premature seal wear. The centre trunnion mount allows the cylinder to self-align in one plane, but it does not support the rod against lateral forces.
Quick checklist
At the standard operating pressure of 0.7 MPa, the push force is 1374 N. At the maximum operating pressure of 0.9 MPa, it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is dimensionally shorter than a standard ISO 15552 cylinder. It is not a direct replacement. Use it to replace another AirTAC SC50 cylinder with matching bore, stroke, PT ports, and TC mount.
