The AirTAC Airtac SC40 Standard Cylinder SC40X350TC 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 SC40X350TC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore, 16 mm rod, and 350 mm stroke suit mid-range linear actuation tasks where a pivoting mount is required.
This model features a TC centre trunnion mount, supplied with the TCM1 bracket (F-SC40TC), allowing the cylinder to pivot during operation. The tie-rod construction keeps the body length compact at 142 mm (A dimension), with a 21 mm adjustable air cushion at each end for smooth deceleration.

The 350 mm stroke and centre trunnion mount allow the SC40X350TC to pivot a diverter gate on a packaging or sorting conveyor, smoothly redirecting products between lanes.
Delivers 628 N of clamping force at 0.5 MPa, ideal for holding workpieces in CNC fixtures or welding jigs where the cylinder body needs to pivot slightly during engagement.
The trunnion mount handles the arcing motion of linkage arms on seeders or sprayer booms. The TPU seals and tie-rod design withstand dusty, outdoor conditions within the -20 to +70 °C range.
Choose the SC40 bore for push forces around 628 N at 0.5 MPa. If you need more force, step up to the SC50 (982 N at 0.5 MPa); for a lighter, more compact option, the SC32 delivers 402 N. This 350 mm stroke is within the 1200 mm maximum standard stroke for bore 40.
For strokes of 300 mm or more, be cautious with side loads—an unsupported 16 mm rod can bend under lateral force. Use an external guide rail or switch to a guided cylinder if the load is not perfectly axial. When replacing an existing cylinder, match the 40 mm bore, 350 mm stroke, PT1/4 port thread, TC centre trunnion mount, and the absence of a magnet sensor 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 0.7 MPa, push force increases to 879 N, and at the maximum operating pressure of 0.9 MPa, it reaches 1130 N.
The TC suffix means this specific model includes a centre trunnion mount (F-SC40TC) designed for pivoting applications. If you need a rigid foot mount, you would order the LB variant (SC40X350LB). The trunnion bracket is supplied with the cylinder.
