The AirTAC SC40 Standard Cylinder SC40X1050 is a genuine double-acting standard air cylinder with a Ø40mm bore and 1050mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X1050 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, pairing a 40 mm bore with an extended 1050 mm stroke. At 0.5 MPa operating pressure, it generates a push force of 628 N and a pull force of 528 N, rising to 1130 N of thrust at the maximum 0.9 MPa rating.
This model features a 16 mm diameter piston rod with M12x1.25 threads and PT1/4 port connections. The body length A is 142 mm, giving a total extended length of approximately 1192 mm. It includes a 21 mm adjustable air cushion at each end to decelerate the piston smoothly, and is built with standard TPU seals for a -20 to +70 C temperature range.

Extends 1050 mm across wide conveyors to push or divert cartons and totes between lines, using the full stroke without complex linkages.
Provides the long linear motion needed to tilt or dump large panels and sheets from a flat stack into a vertical orientation at a processing station.
Operates a tall sliding gate or diverter chute at the bottom of a bulk material hopper, using the 1050 mm stroke to fully open the flow path.
Select the SC40X1050 for applications needing a long stroke within the 40 mm bore's 1200 mm maximum standard limit. If your force requirement is higher, stepping up to the 50 mm bore provides 982 N of push force at the same 0.5 MPa pressure. For strokes this long, carefully manage side loads: an unsupported 1050 mm rod is susceptible to bending under lateral force. Use an external linear guide or switch to a guided cylinder unit to protect the rod bearings and ensure reliable, bind-free operation over the full cycle.
Quick checklist
At 0.7 MPa (7 bar) supply pressure, this 40 mm bore cylinder produces a theoretical push force of 879 N. The pull force on the rod side is slightly lower at 528 N at 0.5 MPa due to the area occupied by the 16 mm rod.
No, the AirTAC SC series is a tie-rod design and is physically shorter than a standard ISO 15552 cylinder, so it is not dimensionally interchangeable. Match it only with another AirTAC SC 40 mm bore cylinder with the same 1050 mm stroke, PT1/4 ports, and basic mounting.
