The AirTAC Airtac SC40 Standard Cylinder SC40X195S is a genuine double-acting standard air cylinder with a Ø40mm bore and 195mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X195 is a double-acting tie-rod cylinder delivering 628 N of push force and 528 N of pull force when operated at 0.5 MPa. With a 40 mm bore and 195 mm stroke, it is well-suited for moderate clamping, sorting, and material-handling tasks where a compact envelope is required.
This model features a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The body length A is 142 mm, giving a total extended length of approximately 337 mm. An adjustable pneumatic cushion softens end-of-stroke impact over the final 21 mm, protecting the end caps and reducing noise.

The 195 mm stroke and 628 N push force reliably actuate diverter gates and sorting paddles on medium-duty package handling lines.
Applies consistent 528 N pull force for part holding in CNC fixtures and assembly jigs, with adjustable cushioning for smooth operation.
Operates chute doors and flow gates on seed drills and fertilizer spreaders, tolerating dusty conditions with its robust tie-rod construction.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at the same 0.5 MPa pressure. If space is tight and the load is lighter, the 32 mm bore SC32 series offers 402 N. For strokes of 300 mm or more, consider an external guide or guided cylinder to protect the rod bearing from side-load bending.
When replacing an existing cylinder, match five points: 40 mm bore, 195 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the absence of a magnet. This ensures a direct dimensional and performance swap with another AirTAC SC40 tie-rod cylinder.
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, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder and has a shorter overall body length than a comparable ISO 15552 profile cylinder. It is a direct dimensional replacement only for another AirTAC SC series cylinder with matching bore, stroke, port thread, and mounting configuration.
