The AirTAC Airtac SC40 Standard Cylinder SC40X160STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 160mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X160STC is a 40 mm bore double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 160 mm stroke suits medium-reach clamping and transfer tasks, while the built-in magnet enables direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This configuration includes a centre trunnion mount (TC) with the TCM1 bracket, allowing the cylinder to pivot for swinging loads. The 16 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration. As a genuine AirTAC tie-rod cylinder, it is shorter than an equivalent ISO 15552 profile, making it a practical choice where space is limited.

Pivots a 160 mm stroke arm to shift components between conveyor lanes, using the TC trunnion for smooth angular motion and magnetic sensors for position confirmation.
Applies 628 N of clamping force at 0.5 MPa to hold workpieces during drilling or welding, with the adjustable cushion reducing impact at the end of the stroke.
Operates a pivoting safety guard or diverter gate, where the trunnion mount allows the cylinder to swing freely and the magnet confirms the gate is fully open or closed.
For higher force, step up to the SC50 with 982 N push at 0.5 MPa; for lighter duty, the SC32 provides 402 N. The TC centre trunnion mount (F-SC40TC) is ideal for applications where the cylinder body needs to pivot during the stroke. At 160 mm stroke, side loads are manageable, but ensure the rod is aligned axially to prevent bending.
To replace this cylinder, match five points: 40 mm bore, 160 mm stroke, PT port thread, the TC trunnion mounting, and the -S magnet for sensor compatibility. Standard strokes for the 40 mm bore extend up to 1200 mm.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
The TC mount (part code F-SC40TC) includes a TCM1 trunnion bracket. It attaches to the middle of the cylinder body, allowing it to pivot around the trunnion axis. This is essential for applications where the cylinder must swing to follow an arc, preventing rod bending from misalignment.
