The AirTAC Airtac SC40 Standard Cylinder SC40X1040S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1040mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X1040S is a double-acting tie-rod cylinder with a 40 mm bore and a long 1040 mm stroke, delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration at end-of-travel, while the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable position feedback.
With a compact body length A of 142 mm plus the 1040 mm stroke, this cylinder suits applications needing extended reach without excessive overall length. The PT1/4 port and M12x1.25 rod thread offer standard connectivity, and the TPU seals ensure reliable operation from -20 to +70 °C.

Moves components across wide conveyor gaps or between distant stations, with the 1040 mm stroke covering extended transfer distances.
Opens and closes sliding safety gates or machine guards with full-stroke sensor confirmation via the integrated magnet and CMSG/DMSG switches.
Pushes pallets or heavy trays out of vertical stacks, using the 628 N force at standard plant pressure for reliable material handling.
For applications requiring more force, consider stepping up to the 50 mm bore SC50 series which provides 982 N at 0.5 MPa. For lighter, faster cycles, the 32 mm bore (402 N) may be sufficient. At this 1040 mm stroke, ensure the rod is protected from side loads—external guides or a guided cylinder are recommended to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match these five points exactly: 40 mm bore, 1040 mm stroke, PT1/4 port thread, basic mounting (no bracket), and the -S magnet suffix for sensor compatibility.
Quick checklist
At 0.5 MPa the push force is 628 N and 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.
For strokes over 300 mm, especially with a 16 mm rod, side loads can cause bending. Install an external linear guide or use a guided cylinder to absorb transverse forces. The adjustable air cushion only decelerates the piston—it does not support side loads.
