The AirTAC Airtac SC40 Standard Cylinder SC40X170STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 170mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X170STC is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 170 mm stroke is well within the 1200 mm maximum standard stroke for the 40 mm bore, making it a reliable workhorse for medium-reach linear tasks.
This model features a built-in magnet for CMSG/DMSG/EMSG sensors and a TC centre trunnion mount (supplied with TCM1 bracket) for pivoting applications. The 16 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth end-of-stroke deceleration, while the PT1/4 port thread provides standard pneumatic connections.

The 170 mm stroke and centre trunnion mount allow the cylinder to pivot, smoothly swinging diverter arms on packaging conveyors to sort products by weight or label.
Delivers 1130 N of clamping force at 0.9 MPa, ideal for holding plastic or light metal parts during ultrasonic welding or drilling operations on rotary indexing tables.
The built-in magnet provides open/closed position feedback via solid-state sensors, reliably operating greenhouse roof vents or livestock barn air inlets with a pivoting TC mount.
Choose the SC40 bore when your application requires around 628 N of force at standard plant pressure. If you need significantly more push, step up to the SC50 bore which provides 982 N at 0.5 MPa. For lighter, faster cycles, the SC32 bore offers 402 N.
For a stroke of 170 mm, the SC40's 16 mm rod is generally rigid, but always avoid direct side loads. If lateral forces are present, use an external guide rail. To replace an existing cylinder, match five points exactly: 40 mm bore, 170 mm stroke, PT port thread, TC centre trunnion mounting (F-SC40TC), and the -S magnet for sensor compatibility.
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 increases to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The 'TC' suffix means it comes with a centre trunnion mount and the TCM1 bracket (order code F-SC40TC), allowing the cylinder body to pivot. This is essential for applications where the attached load moves through an arc.
