About the Airtac SC50 Standard Cylinder SC50X187S
The SC50X187S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod family, combining a 50 mm bore with a 187 mm stroke. Its built-in magnet allows CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the barrel for contactless position sensing—ideal for sequence control and end-of-stroke verification.
At 0.5 MPa this model provides 982 N of push force and 825 N of pull force, rising to 1767 N push at the maximum operating pressure of 0.9 MPa. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end deliver smooth deceleration. Total body length A is 150 mm, giving an extended length of approximately 337 mm. Ports are PT1/4, and the rod features an M16x1.5 male thread for tooling attachment.

Where the Airtac SC50 Standard Cylinder SC50X187S Is Used
Packaging & Sorting Gates
The 187 mm stroke and sensor-ready magnet make this cylinder a strong fit for diverting packages on conveyor lines, where end-of-stroke confirmation is required for cycle integrity.
Clamping & Assembly Fixtures
Delivering 982 N at 0.5 MPa, the SC50X187S provides ample force for pneumatic toggle clamps or assembly press fixtures, with magnetic sensors enabling automated part-present detection.
Material Transfer & Lift-Assist
Use this cylinder for pushing or lifting components between stations. The 20 mm rod and adjustable cushion handle moderate guided loads smoothly at speeds up to 800 mm/s.
Is the Airtac SC50 Standard Cylinder SC50X187S the Right Cylinder?
Choose the SC50X187S when your application needs roughly 980 N of force at standard plant air pressure. If you require more force, the SC63 bore steps up to 1559 N push at 0.5 MPa; for a lighter, more compact solution, the SC40 bore provides 628 N. Always match replacement cylinders on five points: 50 mm bore, 187 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting configuration.
For this 187 mm stroke, side loading is a moderate concern. Ensure the load is guided and aligned axially with the rod; if off-axis forces are unavoidable, add an external linear guide or switch to a guided cylinder to protect the rod bearing and seals from premature wear.
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 SC50X187S FAQ
At 0.5 MPa supply pressure the cylinder produces 982 N pushing force and 825 N pulling force. At 0.7 MPa push force is 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N push. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix in SC50X187S indicates a built-in magnet on the piston, so you can fit AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods. This provides non-contact position feedback for PLC or relay control systems.
