The AirTAC Airtac SC32 Standard Cylinder SC32X850STC is a genuine double-acting standard air cylinder with a Ø32mm bore and 850mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X850STC is a double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at 0.9 MPa). With an 850 mm stroke and a 12 mm diameter piston rod, it is built for linear applications requiring moderate force over a long reach.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC suffix, supplied with TCM1 bracket) for pivoting motion. The total extended body length is approximately 990 mm (140 mm body length A + 850 mm stroke).

The 850 mm stroke moves components between distant conveyor stations, with the trunnion mount allowing the cylinder body to pivot as it extends and retracts.
Magnetic piston sensors confirm open/closed positions for diverting items on packaging lines, ensuring reliable sequence control.
The centre trunnion (TC) mount lets the cylinder swing freely, ideal for clamping fixtures that need to retract completely clear of the workpiece.
Choose the SC32 bore for light to medium pneumatic tasks; it provides 402 N at 0.5 MPa. For higher force, step up to the SC40 bore which offers 628 N at the same pressure. The 850 mm stroke is within the 1000 mm maximum standard stroke for bore 32.
For this long 850 mm stroke, be cautious of side loads which can bend the 12 mm rod. Use an external guide or linear rail to absorb lateral forces and protect the rod bearing. When replacing, match bore (32), stroke (850), PT port thread, centre trunnion mounting (F-SC32TC), and the built-in magnet (-S) for sensor compatibility.
Quick checklist
At 0.5 MPa it delivers 402 N pushing and 345 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 724 N. The theoretical maximum at 1.0 MPa is 82 kgf.
Yes. The -S suffix indicates a built-in magnet, allowing AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for end-of-stroke detection.
