The AirTAC SC50 Standard Cylinder SC50X660STC is a genuine double-acting standard air cylinder with a Ø50mm bore and 660mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X660STC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.7 MPa, making it a robust actuator for medium-duty automation. Its 660 mm stroke falls well within the 1200 mm maximum standard stroke for 50 mm bore cylinders, and the 20 mm diameter piston rod provides good column strength for this extended reach.
This model is factory-equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke or mid-stroke position feedback. The TC suffix denotes a centre trunnion mount, supplied with the TCM1 bracket (part code F-SC50TC), which allows the cylinder to pivot and is ideal for swinging or articulating loads. Seals are standard TPU for a -20 to +70 °C operating range, and ports are PT1/4.

The 660 mm stroke and trunnion mount allow the cylinder to swing into position for diverting or transferring parts between conveyor lines, with sensor confirmation at each end of travel.
With 1767 N of clamping force at 0.7 MPa, this cylinder secures workpieces in welding or assembly fixtures. The pivoting TC mount allows the clamp arm to retract clear of the work area.
The centre trunnion pivot point is ideal for mounting a cylinder that rotates a bin or hopper through an arc. The 660 mm stroke provides the necessary linear travel to achieve the required dump angle.
Select the SC50 bore when your application requires between 982 N and 1767 N of force at typical plant pressures. For lower force needs, stepping down to an SC40 bore (879 N at 0.7 MPa) can reduce air consumption and physical size. If you need more power, the SC63 bore provides 2182 N at 0.7 MPa.
At a 660 mm stroke, ensure the rod is not subjected to significant side loading, which can cause rod bearing wear and bending. For applications with lateral forces, use an external linear guide or consider a guided cylinder. For a direct replacement, match these five points: 50 mm bore, 660 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with the F-SC50TC bracket, and the built-in magnet (-S) for sensor compatibility.
Quick checklist
At 0.5 MPa (5 bar), the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes, the TC suffix indicates it is configured with a centre trunnion mount. It is supplied with the TCM1 trunnion bracket (order code F-SC50TC) and is designed to allow the cylinder body to pivot as it strokes, absorbing angular movement in the application.
