The AirTAC SC50 Standard Cylinder SC50X700STC 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 AirTAC SC50X700STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 700 mm stroke suits medium-reach material transfer and actuation tasks, while the 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration at end-of-stroke.
This configuration includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The TC suffix denotes a centre trunnion mount, supplied with the TCM1 bracket (F-SC50TC), which permits the cylinder body to pivot as the load moves through an arc.

The 700 mm stroke and pivoting trunnion mount allow the cylinder to swing a diverter gate smoothly, directing packages or materials between conveyor lanes.
With 1374 N of force at 0.7 MPa and magnetic position feedback, this cylinder provides consistent clamping pressure and end-of-stroke confirmation in automated welding cells.
The centre trunnion mount handles the arcing motion of discharge chutes on harvesters or silage equipment, while the TPU seals operate reliably from -20 to +70 °C.
For higher force requirements, stepping up to the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If a shorter, more compact solution is acceptable, the 40 mm bore offers 628 N. The 700 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
At this stroke length, ensure the rod is not subjected to significant side loading; an external linear guide or rod support is recommended to prevent bending stress on the 20 mm rod. For replacement, match bore, stroke, PT port thread, centre trunnion (TC) mount, and the integrated magnet sensor option.
Quick checklist
At 0.7 MPa (approximately 100 psi), the theoretical push force is 1374 N. At the maximum operating pressure of 0.9 MPa, it reaches 1767 N. The pull force on the retract stroke is 825 N at 0.5 MPa due to the rod area.
No. The SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder, so ISO 15552 mounts are not dimensionally interchangeable. You must use the dedicated AirTAC SC mounting accessories; this model uses the F-SC50TC centre trunnion bracket.
