The AirTAC Airtac SC40 Standard Cylinder SC40X730STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 730mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X730STC is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore, 16 mm piston rod and a 730 mm stroke, it suits medium-reach linear tasks where a compact body length (142 mm + stroke) is required.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, plus a centre trunnion mount (TC suffix, supplied with TCM1 bracket F-SC40TC) that allows the cylinder to pivot during operation. Standard PT1/4 ports and TPU seals (-20 to +70 °C) complete the package.

The 730 mm stroke reaches across wide conveyors to divert or sort medium-weight packages. The trunnion mount lets the cylinder swing with the transfer arm.
628 N of force securely holds workpieces in CNC or welding fixtures. Magnetic sensors confirm clamp/unclamp status for automated safety interlocks.
Operates sliding gates on chutes or hoppers handling grain or aggregate. The centre trunnion absorbs misalignment, and the magnet provides open/closed feedback.
Choose the SC40 when 628 N at 0.5 MPa covers your load. If you need more force, step up to the SC50 (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 offers 402 N. At 730 mm stroke, the 16 mm rod is extended significantly—avoid side loads or pair the cylinder with an external guide to prevent rod bending and premature seal wear.
For replacement, match five points: 40 mm bore, 730 mm stroke, PT1/4 ports, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet for sensor compatibility. This tie-rod design is not an ISO 15552 drop-in; it replaces another AirTAC SC cylinder of identical configuration.
Quick checklist
At 0.5 MPa, the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. These values are based on the 40 mm bore and 16 mm rod diameter.
No. The AirTAC SC series is a tie-rod cylinder that is shorter than an ISO 15552 profile cylinder, so the mounting dimensions differ. You must replace it with another SC40 tie-rod cylinder matching the 730 mm stroke, centre trunnion mount, magnet, and PT1/4 ports.
