The AirTAC Airtac SC40 Standard Cylinder SC40X1100 is a genuine double-acting standard air cylinder with a Ø40mm bore and 1100mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
This AirTAC SC40X1100 double-acting cylinder provides a push force of 628 N at 0.5 MPa, scaling to 1130 N at the maximum operating pressure of 0.9 MPa. The 40 mm bore houses a 16 mm diameter piston rod with an M12x1.25 knuckle thread, and the unit features a 21 mm adjustable air cushion at each end to decelerate the piston smoothly.
With a body length A of 142 mm, the total extended length for this 1100 mm stroke model is approximately 1242 mm. The cylinder uses a PT1/4 port and operates on filtered air within a standard temperature range of -20 to +70 °C, making it a robust choice for long linear movements in general automation.

The 1100 mm stroke is well-suited for transferring parts between distant conveyor lines or workstations where a compact tie-rod cylinder body is needed.
Provides the consistent, extended linear motion required for applying a bead of adhesive along a long seam or gasket path in an assembly process.
Actuates high-reach diverter gates on packaging or sorting lines, using its full 1100 mm stroke to direct products down different chutes.
The SC40X1100 is ideal for applications needing a stroke just under the 1200 mm maximum standard limit for this bore. If your force requirement is higher, consider stepping up to the SC50 series, which delivers 982 N of push force at the same 0.5 MPa pressure. For lower force needs, the SC32 provides 402 N.
For any stroke of 300 mm or more, and especially at 1100 mm, it is critical to manage side loads. An unsupported 16 mm rod at full extension is vulnerable to bending under lateral force. Use an external guide rail or a guided cylinder assembly to protect the rod bearing and ensure a long service life. When replacing this unit, match the 40 mm bore, 1100 mm stroke, PT1/4 port thread, and basic mounting configuration precisely.
Quick checklist
At 0.7 MPa operating pressure, the theoretical push force is 879 N, and the pull force is 528 N. These values are derived from the official AirTAC thrust table for the 40 mm bore.
It is not recommended. The 16 mm rod is subject to bending stress from side loads, especially at full extension. An external guide or a self-guided unit is necessary to prevent premature rod bearing wear and seal failure.
