About the Airtac SC50 Standard Cylinder SC50X15
The AirTAC SC50X15 is a compact-stroke double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 50 mm bore and 15 mm stroke suit short linear positioning tasks where space is tight but clamping or ejecting force must be substantial.
Built on a proven tie-rod design, this cylinder features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end of travel, reducing impact noise. The body length A is 150 mm, giving a total extended length of just 165 mm for easy integration into fixtures.

Where the Airtac SC50 Standard Cylinder SC50X15 Is Used
Short-Stroke Clamping
Delivers a powerful 982 N clamping force at 0.5 MPa in a compact 15 mm stroke, ideal for holding workpieces in CNC fixtures and welding jigs.
Part Ejection
Rapidly ejects small components from injection molds or stamping dies. The short stroke and fast cycle time maximize throughput in automated cells.
Diverter Gate Actuation
Operates small diverter gates on conveyor lines. The 20 mm rod and tie-rod construction provide the rigidity needed for frequent, repetitive actuation.
Is the Airtac SC50 Standard Cylinder SC50X15 the Right Cylinder?
For applications needing slightly more force in the same bore class, the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa. If space and weight are critical and 982 N is sufficient, the SC50 is the right choice. The short 15 mm stroke keeps the envelope minimal.
When replacing an existing cylinder, match five points: 50 mm bore, 15 mm stroke, PT1/4 ports, basic (no bracket) mounting, and no magnet. This model uses the standard TPU seal and PT thread. For guided or side-loaded applications, consider adding an external guide rail, as even short-stroke cylinders are not designed to absorb lateral forces on the rod.
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 SC50X15 FAQ
At 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
No. The SC50X15 is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston will drift or the load will drop. For load holding without pressure, you must add an external rod lock, a mechanical brake, or a pilot-operated check valve.
