About the Airtac SC50 Standard Cylinder SC50X180
The SC50X180 is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and 180 mm stroke, it uses a 20 mm diameter piston rod with M16x1.5 male threads for tooling attachment, making it well-suited for medium-force clamping and pressing tasks.
This model features a body length A of 150 mm and an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly. The standard PT1/4 port and TPU seals provide reliable operation in the standard temperature range of -20 to +70 °C, with no built-in magnet or mounting accessories on this basic configuration.

Where the Airtac SC50 Standard Cylinder SC50X180 Is Used
Part Rejection Gate
Actuates a diverter gate on a packaging conveyor. The 180 mm stroke provides sufficient travel to push rejected items onto a secondary lane, with the 0.5 MPa force class handling light-to-medium product weights.
Assembly Press Fixture
Provides the insertion force for pressing bushings or bearings into housings. The 20 mm rod diameter offers good column strength for the 180 mm extension, resisting buckling under axial loads.
Clamping Station
Operates a hold-down clamp in a woodworking or welding jig. The adjustable cushion prevents jarring at the end of the 180 mm stroke, protecting the fixture from vibration-induced loosening.
Is the Airtac SC50 Standard Cylinder SC50X180 the Right Cylinder?
For applications needing less force, consider stepping down to a 40 mm bore (628 N push at 0.5 MPa). If your load exceeds 982 N at 0.5 MPa, the 63 mm bore offers 1559 N push. For this 180 mm stroke, ensure the rod is not subjected to significant side loading; if side loads are unavoidable, use an external linear guide to protect the rod bearing. When replacing this cylinder, match five key points: 50 mm bore, 180 mm stroke, PT1/4 port thread, basic mounting (no accessory), and the absence of a magnet.
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 SC50X180 FAQ
At 0.7 MPa operating pressure, the SC50X180 produces a theoretical push force of 1374 N. The pull force on the retract stroke at the same pressure is 1155 N, accounting for the reduced piston area on the rod side.
This specific model code SC50X180 does not include the -S suffix, so it is manufactured without a built-in magnet. To use CMSG or DMSG sensors for position feedback, you would need to order the SC50X180-S variant, which includes a magnetized piston ring.
