About the Airtac SC50 Standard Cylinder SC50X180S
The SC50X180S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 180 mm stroke is a standard length within the 1200 mm maximum for the 50 mm bore, making it a readily available workhorse for medium-duty linear actuation.
This model includes a built-in magnet (suffix -S), allowing easy mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback. The 20 mm diameter piston rod and PT1/4 ports ensure reliable power transmission and straightforward pneumatic connection.

Where the Airtac SC50 Standard Cylinder SC50X180S Is Used
Package Sorting Gate
The 180 mm stroke and sensor-ready design make this cylinder ideal for diverting medium-weight packages on conveyor lines, with magnetic sensors confirming gate position at each cycle.
Automated Clamping Fixture
Delivers a consistent 982 N clamping force at standard line pressure. The built-in magnet allows for part-presence verification before a machining or assembly cycle begins.
Material Lift Assist
Used in light-duty vertical lifts or pushers where the 180 mm stroke provides sufficient reach, and the sensor confirms full retraction before the next load is presented.
Is the Airtac SC50 Standard Cylinder SC50X180S the Right Cylinder?
For applications requiring slightly more force, consider stepping up to the 63 mm bore (1559 N at 0.5 MPa). If a lower force profile is sufficient, the 40 mm bore (628 N at 0.5 MPa) offers a more compact alternative. The built-in magnet on this model is essential for automated sequences where non-contact position sensing is required.
When replacing an existing cylinder, match five key points: 50 mm bore, 180 mm stroke, PT port thread, the basic (no bracket) mounting style, and the integrated magnet for sensor compatibility. For strokes over 300 mm, evaluate side loads carefully—an external guide rail is recommended to protect the rod bearing from bending moments.
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 SC50X180S FAQ
At 0.7 MPa operating pressure, the theoretical push force on the extend stroke is 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa, accounting for the 20 mm rod area.
Yes. The -S suffix denotes a built-in magnet in the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position.
