About the Airtac SC40 Standard Cylinder SC40X150FB
The SC40X150FB is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at the 0.9 MPa maximum operating pressure). With a 40 mm bore and 150 mm stroke, it uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports, making it a compact workhorse for medium-duty linear actuation.
This model is configured with an FB rear rectangular flange (accessory F-SC40FB) for rigid end-face mounting. The body length A is 142 mm, giving a total extended length of approximately 292 mm. The adjustable pneumatic cushion at each end decelerates the piston over 21 mm to reduce end-of-stroke impact.

Where the Airtac SC40 Standard Cylinder SC40X150FB Is Used
Part Ejection
The 150 mm stroke and rear flange mount suit fixed-position pushers that eject finished parts from a conveyor or indexing table, where the 628 N push force at 0.5 MPa handles moderate-weight components reliably.
Clamping & Fixturing
Rigid FB flange mounting keeps the cylinder body fixed while the 16 mm rod extends to clamp workpieces in CNC fixtures, welding jigs, or assembly stations, resisting deflection under side load.
Packaging Press
Ideal for a compact press action in packaging machinery—compressing cartons, inserting liners, or sealing flaps with a consistent 150 mm linear stroke and adjustable end-cushion for quiet, low-impact operation.
Is the Airtac SC40 Standard Cylinder SC40X150FB the Right Cylinder?
Select the SC40 when your application needs between roughly 500 N and 880 N of push force at standard shop air (0.5–0.7 MPa). If you require more force, step up to the SC50 bore, which provides 982 N push at 0.5 MPa; for a lighter, more compact solution, the SC32 bore delivers 402 N. This 150 mm stroke is well within the 1200 mm maximum standard stroke for the 40 mm bore.
To ensure a correct replacement, match five points: 40 mm bore, 150 mm stroke, PT1/4 port thread, FB rear flange mounting, and no built-in magnet. Always verify the mounting footprint against the F-SC40FB flange drawing, as the SC tie-rod design is shorter than an ISO 15552 cylinder and is not dimensionally interchangeable with that standard.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC40 Standard Cylinder SC40X150FB FAQ
At 0.5 MPa the cylinder pushes with 628 N and pulls with 528 N. At 0.7 MPa push force rises to 879 N, and at the maximum operating pressure of 0.9 MPa it reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf. Always size for your real working pressure.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder (body length A is 142 mm for the 40 mm bore). The mounting dimensions, tie-rod spacing, and accessory footprints differ. It is a direct replacement only for another AirTAC SC40 tie-rod cylinder with matching stroke, port thread, and FB rear flange.
