The AirTAC Airtac SC40 Standard Cylinder SC40X1150 is a genuine double-acting standard air cylinder with a Ø40mm bore and 1150mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X1150 is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa operating pressure. With a 40 mm bore and a 16 mm diameter piston rod, this model provides a long 1150 mm stroke that is within the 1200 mm maximum standard stroke for this bore size.
This tie-rod cylinder features a compact body length A of 142 mm, adjustable air cushioning for smooth deceleration, and PT1/4 pneumatic ports. It operates on filtered air from 0.15 to 1.0 MPa across a standard temperature range of -20 to +70 °C with its TPU seals.

The 1150 mm stroke is ideal for pushing or pulling bins and boxes across wide conveyor transfer points in distribution centers, providing consistent 628 N force at standard line pressure.
Used in woodworking or sheet metal lines to transfer large panels between processing stations, where the extended reach eliminates the need for complex multi-stage actuators.
Operates slide gates on large hoppers or silos, using its full 1150 mm travel to completely open or close material flow paths in agricultural processing equipment.
Choose the SC40X1150 when your application requires a stroke just under the 1200 mm maximum for a 40 mm bore. If you need higher force, stepping up to the 50 mm bore provides 982 N of push force at 0.5 MPa. For strokes of this length, ensure the rod is protected from side loading; an external linear guide or a guided cylinder configuration is recommended to prevent rod bending and premature bearing wear.
For a direct replacement, match five key points: 40 mm bore, 1150 mm stroke, PT1/4 port thread, the specific mounting accessory (if any), and the magnet option. This model is a basic configuration without a built-in magnet, using standard TPU seals and PT threads.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 628 N and the pull force on the retract stroke is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
For a 1150 mm stroke with a 16 mm rod, direct side loads should be avoided. The rod is designed for axial push/pull forces. If any lateral force is present, you must use an external guide rail or rod support to prevent bending and ensure long service life.
