About the Airtac SC100 Standard Cylinder SC100X185SFA
The SC100X185SFA is a double-acting pneumatic cylinder delivering 3927 N push force at 0.5 MPa (7068 N at 0.9 MPa). Its 185 mm stroke suits medium-reach clamping and pressing operations. The 25 mm diameter piston rod and PT1/2 ports provide robust flow for consistent cycle speeds.
This model includes a built-in magnet (S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The FA front rectangular flange (F-SC100FA) allows rigid mounting on the rod side, ideal for applications where the cylinder body is supported from the front face.

Where the Airtac SC100 Standard Cylinder SC100X185SFA Is Used
Heavy Press-Fit Assembly
Delivers 3927 N at 0.5 MPa for pressing bearings, bushings, or pins into housings with controlled force and speed.
Pallet Stop & Lift
Front-flange mounted to stop or lift heavy pallets on conveyor lines. Magnetic sensors confirm retracted and extended positions for interlocking.
Clamping & Welding Fixtures
Rigid FA flange holds the cylinder steady under high clamping forces during automated welding or machining, with sensor feedback to the PLC.
Is the Airtac SC100 Standard Cylinder SC100X185SFA the Right Cylinder?
Choose the SC100 bore for heavy push forces up to 7068 N at 0.9 MPa. For lighter loads, the SC80 bore offers 2513 N at 0.5 MPa, reducing air consumption. The 185 mm stroke is well within the 1500 mm maximum standard stroke for this bore, ensuring standard availability. The FA front flange centers the rod end precisely on a machine panel.
When replacing, match bore (100 mm), stroke (185 mm), PT1/2 port thread, front flange mounting (FA), and the built-in magnet (-S). This tie-rod cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders. For strokes over 300 mm, consider an external guide to protect the rod from side-load bending.
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 SC100 Standard Cylinder SC100X185SFA FAQ
At 0.5 MPa it produces 3927 N push force; at 0.7 MPa it reaches 5497 N, and at the maximum operating pressure of 0.9 MPa it delivers 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC tie-rod cylinder matching bore, stroke, PT port, FA front flange mount, and -S magnet.
