About the Airtac SC50 Standard Cylinder SC50X385S
The SC50X385S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), built around a 50 mm bore and a 20 mm diameter piston rod. Its 385 mm stroke is well within the 1200 mm maximum standard stroke for this bore, and the adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-travel.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The body length A is 150 mm, giving a total extended length of approximately 535 mm. Ports are PT1/4 with an M16x1.5 rod thread, and the standard TPU seals suit operating temperatures from -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X385S Is Used
Packaging Line Diverters
The 385 mm stroke and 982 N push force at 0.5 MPa reliably actuates diverter gates and pusher arms on medium-speed packaging conveyors, with the magnetic piston enabling sensor-based cycle counting.
Automated Welding Fixtures
Clamps and positions components in robotic welding cells. The built-in magnet allows CMSG/DMSG sensors to confirm clamp closure before the weld cycle starts, improving safety and repeatability.
Material Handling Stops
Operates pallet stops and lift gates in gravity roller conveyors. The 20 mm rod and adjustable cushion handle impact deceleration smoothly, while the magnetic piston verifies gate position.
Is the Airtac SC50 Standard Cylinder SC50X385S the Right Cylinder?
Choose the SC50X385S when your application needs around 980 N of force at standard plant pressure and a mid-range stroke with sensor feedback. If you need more force, the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa; for a lighter, more compact solution, the 40 mm bore SC40 series delivers 628 N. The built-in magnet makes this cylinder ready for end-of-stroke or mid-stroke position verification without adding external brackets.
For a 385 mm stroke, ensure the load is guided and side forces are minimal. Long unsupported strokes on a 20 mm rod can experience bending under side load; use an external guide rail or rod-alignment coupler to protect the rod bearing and seals. When replacing an existing cylinder, match five points: 50 mm bore, 385 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no accessory) mounting configuration.
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 SC50X385S FAQ
At 0.5 MPa, the push force is 982 N; at 0.7 MPa, it rises to 1374 N. The maximum operating pressure of 1.0 MPa produces 1767 N of push force. The pull force on the retract stroke is lower due to the rod area: 825 N at 0.5 MPa. All figures are theoretical; factor in a safety margin for friction and dynamic loads.
Yes. The -S suffix in SC50X385S indicates a built-in magnet on the piston. AirTAC CMSG, DMSG, or EMSG series sensors clamp directly onto the cylinder's tie-rod barrel without additional brackets, providing non-contact end-of-stroke or mid-stroke position feedback.
