About the Airtac SC50 Standard Cylinder SC50X100S
The SC50X100S is a double-acting pneumatic cylinder with a 50 mm bore and 100 mm stroke, factory-equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors. At 0.5 MPa it supplies 982 N push force and 825 N pull force, making it a capable mid-range actuator for automated positioning and clamping.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, and the compact tie-rod body has a length A of 150 mm. With the -S magnet, stroke-end sensing is tool-free — simply snap a sensor onto the barrel tie-rod.

Where the Airtac SC50 Standard Cylinder SC50X100S Is Used
Conveyor Diverter Gate
The 100 mm stroke and magnetic piston allow end-of-stroke sensing to confirm gate position on a sorting conveyor, handling 982 N push force at standard plant pressure.
Small-Part Clamping Fixture
Delivers controlled clamping force with sensor feedback for automated CNC or assembly jigs, where the 50 mm bore provides a firm hold without deforming delicate components.
Case Packer Pusher
Pushes cartons or trays 100 mm into a packaging station. The built-in magnet enables cycle counting and jam detection via barrel-mounted sensors.
Is the Airtac SC50 Standard Cylinder SC50X100S the Right Cylinder?
For lighter loads, stepping down to a 40 mm bore (628 N push at 0.5 MPa) saves space and air consumption; for heavier tooling, the 63 mm bore delivers 1559 N at the same pressure. When replacing an existing cylinder, match five points: 50 mm bore, 100 mm stroke, PT1/4 port thread, the -S magnet for sensor compatibility, and the basic (no bracket) mounting. If side loads are present even at this moderate stroke, use an external linear guide or switch to a guided cylinder — tie-rod bearings are not designed to absorb lateral forces.
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 SC50X100S FAQ
At 0.5 MPa the cylinder generates 982 N push and 825 N pull. At 0.7 MPa push rises to 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N push force. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes — the -S suffix means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without any additional brackets or modifications.
