The AirTAC Airtac SC40 Standard Cylinder SC40X320 is a genuine double-acting standard air cylinder with a Ø40mm bore and 320mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X320 is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa, scaling up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore and 320 mm stroke, this model uses a 16 mm diameter piston rod and PT1/4 ports, making it a capable mid-range actuator for linear motion tasks.
This cylinder features an adjustable pneumatic cushion (21 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The total extended body length is approximately 462 mm, combining the 142 mm base body length with the 320 mm working stroke. As a genuine AirTAC component, it is built for reliable service with filtered air in standard industrial environments.

Provides the 628 N push force at 0.5 MPa needed to reliably actuate diverter gates on conveyor lines, directing packages or components with a 320 mm stroke for wide belt coverage.
Delivers up to 1130 N of force at 0.9 MPa for holding workpieces during machining or assembly. The 320 mm stroke allows the clamp to retract fully for easy part loading and unloading.
Ideal for pushing totes or bins off a gravity roller lane onto a takeaway conveyor. The 40 mm bore provides sufficient force to move moderate loads across the full 320 mm travel.
Select the SC40X320 when your application requires a force between the smaller SC32 (402 N at 0.5 MPa) and the larger SC50 (982 N at 0.5 MPa). For strokes of 300 mm or more, carefully evaluate side-loading conditions; the 16 mm rod on this 40 mm bore cylinder can be susceptible to bending under high lateral forces. In such cases, use an external linear guide or a guided cylinder to protect the rod and bearing.
For a direct replacement, match five key specifications: 40 mm bore, 320 mm stroke, PT1/4 port thread, the specific mounting accessory (this is a basic model with no bracket), and the absence of a magnetic piston. This ensures dimensional and functional interchangeability with an existing AirTAC SC40X320.
Quick checklist
At the standard operating pressure of 0.7 MPa, the push force is 879 N and the pull force is 528 N. The maximum push force at 0.9 MPa is 1130 N. These values are based on the 40 mm bore and 16 mm rod diameter.
The SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. It is a direct replacement only for an AirTAC SC40 cylinder or another manufacturer's tie-rod cylinder that matches the 40 mm bore, 320 mm stroke, PT1/4 ports, and basic mounting configuration.
