The AirTAC Airtac SC40 Standard Cylinder SC40X40TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 40mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X40TC is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 40 mm stroke suit short linear actuation tasks where space is tight but reliable clamping or pressing force is required.
This model is factory-configured with a TC centre trunnion mount (includes TCM1 bracket, part code F-SC40TC), allowing the cylinder body to pivot during operation. The 16 mm diameter piston rod, PT1/4 ports, and adjustable air cushion at each end provide smooth deceleration in a compact 142 mm body length.

Delivers 628 N at 0.5 MPa for secure workpiece clamping in CNC machining and welding jigs, with the trunnion mount allowing the cylinder to pivot into position.
The short 40 mm stroke and pivoting TC mount make it effective for quick-acting gates or diverters on small conveyor lines, sorting packages or components.
Suited for driving mechanical linkages and levers where the cylinder body must oscillate, providing consistent push-pull force in packaging and assembly machinery.
For applications needing a pivoting mount, the TC centre trunnion is ideal as it handles swinging loads without binding. If your force requirement is lower, the 32 mm bore SC32 series provides 402 N at 0.5 MPa; for higher force, step up to the 50 mm bore SC50 delivering 982 N. When replacing an existing cylinder, match bore, 40 mm stroke, PT1/4 port thread, the TC trunnion mount, and confirm if a magnet sensor is needed—this model does not include the -S magnet option.
Quick checklist
At the standard 0.5 MPa operating pressure, 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 TC code indicates the cylinder is supplied with the centre trunnion (F-SC40TC) and TCM1 bracket. The trunnion is pinned to the cylinder body and is not intended to be removed for basic foot mounting; if a fixed mount is needed, select a basic or LB foot mount model instead.
