The AirTAC SC50 Standard Cylinder SC50X70STC is a genuine double-acting standard air cylinder with a Ø50mm bore and 70mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X70STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa operating pressure. Its 70 mm stroke is well within the 1200 mm maximum for the 50 mm bore, and the 20 mm diameter piston rod provides robust linear guidance for short-travel clamping and positioning tasks.
This model is factory-equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and the TC centre trunnion mount (supplied with TCM1 bracket, order code F-SC50TC) allows the cylinder to pivot freely under swinging loads. The body length A is 150 mm, giving a compact footprint for machinery with limited space.

The 70 mm stroke and centre-trunnion pivot action suit compact diverter gates on packaging conveyors. Magnetic piston sensors confirm gate position at each end of travel.
Delivers 1767 N clamping force at 0.9 MPa. The trunnion mount lets the cylinder body swing as the clamp arm closes, preventing rod side-load in automated welding cells.
Ideal for small test rigs requiring a pivoting actuator. The 20 mm rod and adjustable air cushion provide smooth, repeatable motion for cycle-testing components.
Choose the SC50 bore for mid-range force applications; stepping down to a 32 mm bore reduces push force to 402 N at 0.5 MPa, while moving up to 63 mm provides 1559 N. The 70 mm stroke is standard and keeps the rod well-supported, but for strokes exceeding 300 mm always evaluate side-load conditions and consider an external guide or guided cylinder to protect the rod bearing from bending moments.
When replacing an existing unit, match five points exactly: 50 mm bore, 70 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This ensures a direct fit with another AirTAC SC tie-rod cylinder of the same configuration.
Quick checklist
At 0.7 MPa supply pressure, the SC50 bore generates 1374 N of push force and 825 N of pull force on the retract stroke. The maximum operating force at 0.9 MPa is 1767 N push.
Yes, provided the original is a 50 mm bore, 70 mm stroke tie-rod cylinder with PT ports, centre trunnion (TC) mount, and a magnetic piston for sensors. The SC50X70STC includes the TCM1 trunnion bracket and is dimensionally consistent with other AirTAC SC series cylinders of the same configuration.
