The AirTAC Airtac SC40 Standard Cylinder SC40X800FA is a genuine double-acting standard air cylinder with a Ø40mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X800FA is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 40 mm bore and 800 mm stroke make it a practical choice for medium-reach linear actuation tasks where a compact body length is beneficial.
This model is equipped with an FA front rectangular flange (F-SC40FA) for secure panel or bulkhead mounting at the rod end. The 16 mm diameter piston rod and PT1/4 port ensure reliable air flow, while the adjustable air cushion at each end decelerates the piston smoothly over a 21 mm cushion length, protecting the end caps during high-speed operation.

The front flange secures the cylinder directly to a fixture plate, providing a rigid base for clamping, pressing, or holding parts during assembly.
With an 800 mm stroke, it pushes components across a conveyor or between stations where a front-mounted cylinder body is preferred for alignment.
Delivers consistent linear force in material test rigs or durability testers, where the flange mount ensures stable, repeatable positioning.
Select the SC40X800FA when your application requires a 40 mm bore with an 800 mm stroke and front-flange mounting. If your force needs are higher, stepping up to the 50 mm bore provides 982 N of push force at the same 0.5 MPa pressure. For lower force requirements, the 32 mm bore offers 402 N. At this 800 mm stroke, ensure the rod is not subjected to significant side loading; an external guide rail is recommended to prevent rod bending and premature bearing wear. When replacing, match bore, stroke, PT port thread, the FA front flange mount, and the non-magnet configuration to ensure a direct fit.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force 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.
No. The AirTAC SC is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC40 cylinder with the same stroke, PT ports, FA front flange mount, and no magnet.
