The AirTAC Airtac SC40 Standard Cylinder SC40X750STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 750mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X750STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa. With a 750 mm stroke and a 16 mm diameter piston rod, it is well-suited for medium-reach linear tasks in material handling and assembly fixtures.
This model includes a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors and ships with a centre trunnion (TC) mount and TCM1 bracket (F-SC40TC), allowing the cylinder body to pivot during operation. The standard TPU seals provide reliable performance from -20 to +70 °C.

Moves components between conveyor lanes with a 750 mm reach, using trunnion mounting to swing into position without binding.
Provides 628 N of clamping force at standard line pressure, with magnetic sensors confirming jaw position in automated welding cells.
Drives a pivoting arm mechanism where the cylinder body must oscillate; the TC mount handles the angular movement cleanly.
For higher force requirements, consider stepping up to the 50 mm bore SC50 series, which provides 982 N of push force at 0.5 MPa. For lighter, more compact applications, the 32 mm bore offers 402 N. At a 750 mm stroke, ensure the rod is supported against side loads; an external linear guide is recommended if the load is not purely axial to prevent rod bending and premature bearing wear. To replace an existing cylinder, match the 40 mm bore, 750 mm stroke, PT port thread, TC centre trunnion mounting, and the integrated magnet sensor compatibility.
Quick checklist
At 0.5 MPa (5 bar), the theoretical 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.
Yes, the 'TC' suffix indicates it is supplied with a centre trunnion mount and the TCM1 trunnion bracket (order code F-SC40TC). The cylinder body can pivot on this bracket.
