About the Airtac SC50 Standard Cylinder SC50X185
The SC50X185 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, pairing a 50 mm bore with a 185 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, making it a capable mid-range actuator for general automation.
This model features a 20 mm diameter piston rod with M16x1.5 male threads, PT1/4 port connections, and a 21 mm adjustable air cushion at each end. The body length A is 150 mm, giving a total extended length of approximately 335 mm. Standard TPU seals provide a -20 to +70 °C working range, and the basic configuration ships without magnet or mounting accessories.

Where the Airtac SC50 Standard Cylinder SC50X185 Is Used
Part Transfer & Indexing
The 185 mm stroke moves components between conveyor lanes or into a pick point. The 20 mm rod and adjustable cushion handle repetitive stops smoothly.
Clamping & Light Pressing
With 1767 N of force at 0.9 MPa, the SC50X185 applies consistent clamping pressure for assembly fixtures, gluing stations, or light press-fit operations.
Gate & Diverter Actuation
Operates a product gate or lane diverter on a packaging line. The tie-rod construction allows easy maintenance in high-cycle material-handling environments.
Is the Airtac SC50 Standard Cylinder SC50X185 the Right Cylinder?
Choose the SC50 bore when your application needs roughly 980–1770 N of push force; stepping down to a 40 mm bore drops the 0.5 MPa push to 628 N, while moving up to a 63 mm bore raises it to 1559 N. The 185 mm stroke is within the 1200 mm maximum standard stroke for this bore, so it is a stock-configuration length.
For replacement, match five points: 50 mm bore, 185 mm stroke, PT1/4 ports, basic (no mounting accessory), and no magnet. If you later add a CMSG/DMSG sensor, order the -S magnet variant. At this stroke length the rod is well supported, but if side loads are present consider an external guide or a guided cylinder to protect the rod bearing.
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 SC50X185 FAQ
At 0.7 MPa supply pressure the SC50X185 produces 1374 N of pushing force and 1155 N of pulling force. The maximum operating pressure is 1.0 MPa, delivering 1963 N push.
No. The SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder, so mounting dimensions and body length differ. It is a direct replacement only for another AirTAC SC50 cylinder with matching stroke, port thread, and mounting configuration.
