About the Airtac SC50 Standard Cylinder SC50X265S
The SC50X265S is a double-acting pneumatic cylinder with a 50 mm bore and 265 mm stroke, pre-fitted with a magnet for direct mounting of CMSG/DMSG/EMSG sensors. At 0.5 MPa it supplies 982 N extending force and 825 N retracting, moving up to a 200 kgf theoretical load at 1.0 MPa.
This tie-rod cylinder uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end provides a 21 mm deceleration zone, and the body length A is 150 mm. Its standard TPU seals suit ambient temperatures from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X265S Is Used
Part Transfer & Sorting
The 265 mm stroke pushes or diverts components between conveyor lanes. The built-in magnet confirms end-of-stroke with a CMSG sensor, ensuring reliable sequencing in automated lines.
Assembly Press & Clamping
With 982 N at 0.5 MPa, this cylinder applies consistent clamping force for gluing, riveting, or light press-fit assembly. The adjustable cushion softens the stop, protecting tooling from impact.
Sensor-Controlled Actuation
The -S magnet variant is purpose-built for position feedback. Mount DMSG solid-state sensors to detect piston position for quality checks, stroke counting, or interlocking safety gates.
Is the Airtac SC50 Standard Cylinder SC50X265S the Right Cylinder?
Choose the SC50 bore for mid-range clamping, pressing, and transfer tasks where 982 N at 0.5 MPa fits the load. If you need more force, the SC63 delivers 1559 N at the same pressure; for a lighter compact design, the SC40 provides 628 N. The 265 mm stroke is within the 1200 mm maximum standard stroke for this bore.
For exact replacement, match five points: 50 mm bore, 265 mm stroke, PT1/4 ports, the built-in magnet (-S suffix), and your existing mounting accessory. The sensor magnet lets you add reed or solid-state switches directly onto the tie-rod barrel without extra brackets.
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 SC50X265S FAQ
At 0.7 MPa (7 bar) the theoretical push force is 1374 N. The pull force on the return stroke is slightly lower because the rod reduces the effective piston area. Always apply a 30-50% safety margin for dynamic loads.
Yes, the SC50X265S is mechanically identical to a non-magnet SC50X265. The -S suffix simply adds a magnetic ring on the piston so you can clamp CMSG reed or DMSG solid-state sensors onto the tie-rod barrel. It works with the same mounts, ports, and cushions.
