About the Airtac SC50 Standard Cylinder SC50X38S
The SC50X38S is a 50 mm bore double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a compact 38 mm stroke. At 0.5 MPa it generates 982 N extending thrust and 825 N on the retract, while the 0.9 MPa maximum operating pressure raises push force to 1767 N — a solid mid-range actuator for short linear moves.
This model includes the -S suffix, equipping the cylinder with a built-in magnet. That lets you clip CMSG, DMSG or EMSG reed and solid-state sensors directly onto the tie-rod barrel for reliable end-of-stroke or mid-position sensing. The 20 mm diameter piston rod, PT1/4 ports and 21 mm adjustable air cushion are standard for the 50 mm bore, and the body length A is 150 mm.

Where the Airtac SC50 Standard Cylinder SC50X38S Is Used
Sensor-Controlled Sorting Gate
The built-in magnet and 38 mm stroke make this cylinder ideal for a compact diverter gate on a conveyor. CMSG sensors confirm open/closed position for precise, repeatable product sorting at typical line speeds.
Short-Stroke Clamping Fixture
Delivers 1767 N of clamping force at 0.9 MPa in a short 38 mm stroke. The magnetic piston allows sensor feedback to verify the part is clamped before a machining cycle starts.
Case Packer Pusher Plate
Pushes products a short distance into a shipping case. The 982 N force at 0.5 MPa handles moderate-weight items, and the adjustable cushion prevents jarring stops that could disturb product orientation.
Is the Airtac SC50 Standard Cylinder SC50X38S the Right Cylinder?
Choose the SC50 when your application needs around 1000 N of push force at typical shop air. If you require a more compact body for the same force class, the 40 mm bore delivers 628 N at 0.5 MPa; stepping up to the 63 mm bore provides 1559 N at 0.5 MPa for heavier payloads. The 38 mm stroke is a standard option within the 50 mm bore’s 1200 mm maximum.
For a direct replacement, match five points: 50 mm bore, 38 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X38S FAQ
At 0.7 MPa (7 bar) the SC50X38S produces 1374 N of extending force. The pull force on the retract stroke at the same pressure is 825 N, accounting for the 20 mm rod area.
Yes. The -S suffix means a magnet is built into the piston. You can mount CMSG (reed) or DMSG/EMSG (solid-state) sensors directly on the tie-rod barrel to detect piston position without any modification.
