The AirTAC Airtac SC40 Standard Cylinder SC40X350SFB is a genuine double-acting standard air cylinder with a Ø40mm bore and 350mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X350SFB is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 350 mm stroke suits medium-reach material handling and pressing tasks, while the 16 mm diameter piston rod provides solid column strength for axial loads.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors on the barrel, plus an FB rear rectangular flange (F-SC40FB) for secure end-face mounting. The 21 mm adjustable air cushion at each end decelerates the piston smoothly, reducing end-of-stroke impact.

The 350 mm stroke and 628 N push force move workpieces between conveyor lanes or into light assembly nests, with magnetic sensors confirming end-of-travel.
Applies consistent clamping force in woodworking or light metal fab jigs. The rear flange mount bolts directly to a machine bulkhead for rigid alignment.
Drives diverter gates in package handling lines. The adjustable cushion absorbs gate inertia quietly, and the magnet allows position feedback to the line controller.
Choose the SC40 bore when your application needs around 628 N at standard shop air. If you require more force, stepping up to the SC50 bore provides 982 N push at the same 0.5 MPa. For strokes of 350 mm and above, watch for side loading on the 16 mm rod—consider an external linear guide or a guided cylinder to prevent rod bearing wear and bending. When replacing an existing cylinder, match five points: bore (40 mm), stroke (350 mm), port thread (PT 1/4), rear flange mounting (FB), and the built-in magnet (-S) for sensor compatibility.
Quick checklist
At 0.7 MPa operating pressure, the push force on the piston rod extension is 879 N. The pull force at the same pressure is lower due to the rod area, delivering 528 N at 0.5 MPa (confirm pull at 0.7 MPa from the full datasheet).
Yes. The -S suffix in SC40X350SFB means a magnet is built into the piston, so you can clamp CMSG reed switches or DMSG/EMSG solid-state sensors directly onto the barrel to detect piston position without external brackets.
