About the Airtac SC50 Standard Cylinder SC50X38
The SC50X38 is a compact-stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable end-of-stroke deceleration for short, repetitive linear moves.
With a body length A of just 150 mm, this 50 mm bore cylinder is notably shorter than an equivalent ISO 15552 profile unit, making it a practical choice where machine space is tight. The 38 mm stroke is a non-standard length, confirming its specification for a dedicated fixture or compact automation task.

Where the Airtac SC50 Standard Cylinder SC50X38 Is Used
Short-Stroke Clamping
The 38 mm stroke and 982 N force at 0.5 MPa suit compact pneumatic clamps and holding fixtures on CNC machining centres, where a fast, repeatable linear lock is needed.
Part Stops and Diverters
Ideal for actuating a short-throw stop gate or diverter arm on a packaging conveyor, using the 20 mm rod to reliably halt or redirect lightweight cartons.
Press-Fit Assembly
Delivers a controlled 1767 N push at 0.9 MPa for light press-fit insertion of bearings or bushings in benchtop assembly cells, with the adjustable cushion softening the end of the stroke.
Is the Airtac SC50 Standard Cylinder SC50X38 the Right Cylinder?
For applications needing slightly more force, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at 0.5 MPa. If a lower force profile is acceptable, the 40 mm bore SC40 series offers 628 N at the same pressure. This model uses standard PT1/4 ports and a basic mount configuration.
When replacing this cylinder, match five key points: the 50 mm bore, the exact 38 mm stroke, the PT port thread, the basic (no bracket) mounting style, and the absence of a magnet. The short stroke keeps the rod well-supported within the bearing, minimizing side-load risk.
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 SC50 Standard Cylinder SC50X38 FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 N. This increases to 1374 N at 0.7 MPa and reaches a maximum of 1767 N at the 0.9 MPa upper operating limit.
Only if the machine's tooling and clearance allow for the extra 12 mm of travel. The SC50X38 is a non-standard stroke, so a direct dimensional replacement must match the 38 mm stroke exactly to avoid interference with the fixture.
