About the Airtac SC50 Standard Cylinder SC50X350SN
The SC50X350SN is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 350 mm stroke. At 0.5 MPa it generates 982 N pushing force and 825 N pulling force, rising to 1767 N push at the 0.9 MPa maximum operating pressure. The piston rod is 20 mm diameter with M16x1.5 male threads, and the adjustable air cushion at each end provides a 21 mm deceleration zone for smooth cycle ends.
This model is factory-equipped with a built-in magnet (-S suffix) so CMSG/DMSG/EMSG reed or solid-state sensors can clamp directly onto the barrel for non-contact position sensing. The N suffix specifies NBR (nitrile) seals, and the port thread is standard PT1/4. The body length A is 150 mm, giving a total extended length of approximately 500 mm. It suits medium-force clamping, pressing, and transfer tasks where sensor feedback is required.

Where the Airtac SC50 Standard Cylinder SC50X350SN Is Used
Sensor-Controlled Clamping
The built-in magnet allows CMSG/DMSG sensors to confirm clamp position before a cycle starts, ideal for automated welding or assembly fixtures requiring 982 N clamping force.
Part Transfer & Sorting
With a 350 mm stroke and sensor feedback, this cylinder reliably pushes or diverts medium-weight packages on conveyor lines, confirming end-of-stroke for sequencing.
Press & Forming Assist
Delivers up to 1767 N at 0.9 MPa for light press-fit, staking, or forming operations where NBR seals offer good wear resistance in lubricated air systems.
Is the Airtac SC50 Standard Cylinder SC50X350SN the Right Cylinder?
Choose the SC50 bore when your application needs around 982 N of push force at standard plant air pressure. If you need more force, stepping up to the SC63 delivers 1559 N at the same 0.5 MPa; if you need less, the SC40 provides 628 N. For this 350 mm stroke, ensure the rod is not subjected to significant side loading—long, unsupported strokes can cause rod bearing wear and bending. Use an external linear guide or a guided cylinder if side forces are present.
When replacing an existing cylinder, match five points: 50 mm bore, 350 mm stroke, PT1/4 port thread, the built-in magnet for sensors, and the NBR seal material. This SC tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with those types.
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 SC50X350SN FAQ
At 0.5 MPa supply pressure, the pushing force is 982 N and the pulling force is 825 N. At the maximum operating pressure of 0.9 MPa, the pushing force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet inside the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's sensor groove to detect piston position without additional brackets.
