About the Airtac SC50 Standard Cylinder SC50X185S
The AirTAC SC50X185S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. Its 185 mm stroke is a standard length within the 1200 mm maximum for the 50 mm bore, making it a readily available workhorse for medium-force linear tasks.
The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position sensing. With a 20 mm rod, M16x1.5 rod thread, and PT1/4 ports, this model includes a 21 mm adjustable air cushion to decelerate the piston smoothly at stroke end.

Where the Airtac SC50 Standard Cylinder SC50X185S Is Used
Material Stops & Diverters
The 982 N push force at 0.5 MPa is well-suited for stopping or diverting medium-weight packages on conveyor lines, with the 185 mm stroke providing ample reach across standard belt widths.
Clamping & Pressing
Ideal for pneumatic clamping fixtures and light assembly presses, where the built-in magnet allows sensors to confirm full extension and retraction for process interlocking.
Gate & Door Actuation
Commonly used to open and close hopper gates or small safety doors, where the adjustable cushion ensures quiet, low-impact operation at the end of the 185 mm travel.
Is the Airtac SC50 Standard Cylinder SC50X185S the Right Cylinder?
Select the SC50 when your application requires roughly 1000 N of force; if you need around 600 N, consider stepping down to the SC40 bore (628 N at 0.5 MPa), or move up to the SC63 (1559 N at 0.5 MPa) for heavier loads. For strokes over 300 mm, evaluate side-load forces on the 20 mm rod and consider an external linear guide to prevent rod bearing wear and bending.
For a direct replacement, match five key points: 50 mm bore, 185 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic tie-rod mounting footprint. This cylinder is shorter than an ISO 15552 profile and must be replaced by another AirTAC SC tie-rod unit with the same configuration.
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 SC50X185S FAQ
At the standard factory pressure of 0.5 MPa, the cylinder provides 982 N pushing force and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet is integrated into the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG series sensors directly onto the tie-rod barrel to detect piston position without any additional brackets or modifications.
