About the Airtac SC100 Standard Cylinder SC100X185STC
The SC100X185STC is a double-acting pneumatic cylinder with a 100 mm bore and 185 mm stroke, delivering a push force of 3927 N at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. This model is equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion (TC) mount, supplied with the TCM1 bracket, allowing the cylinder to pivot during operation.
With a 25 mm diameter piston rod and PT1/2 ports, this tie-rod cylinder is designed for applications requiring a compact footprint, as its body length A of 188 mm is shorter than an equivalent ISO 15552 profile. The adjustable air cushion (29 mm) at both ends decelerates the piston smoothly, reducing impact noise and vibration at the end of the 185 mm stroke.

Where the Airtac SC100 Standard Cylinder SC100X185STC Is Used
Material Handling Gates
Pivots a diverter gate on a conveyor line using the centre trunnion mount. The 3927 N push force at 0.5 MPa easily directs packages or bulk materials, while the built-in magnet provides end-of-stroke confirmation to the PLC.
Clamping & Welding Fixtures
Operates a pivoting clamp arm in an automotive welding jig. The adjustable cushion ensures a soft stop without disturbing the part position, and the magnetic piston allows sensor feedback for robotic interlock sequences.
Press Feed Mechanisms
Actuates a swinging feed arm on a stamping press. The 7068 N of force at 0.9 MPa provides ample power for heavy stock, and the trunnion mount accommodates the arc of the feed motion without side-loading the rod.
Is the Airtac SC100 Standard Cylinder SC100X185STC the Right Cylinder?
For applications needing slightly less force, consider stepping down to the 80 mm bore (2513 N push at 0.5 MPa); if higher force is required, the 125 mm bore offers 6136 N push at the same pressure. The centre trunnion mount (F-SC100TC) is ideal for pivoting loads, but ensure the cylinder is free to swing and that rigid piping allows for this movement. When replacing an existing cylinder, match five key points: 100 mm bore, 185 mm stroke, PT1/2 port thread, the TC centre trunnion mounting accessory, and the -S magnet for sensor compatibility.
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 SC100X185STC FAQ
At the standard operating pressure of 0.7 MPa, the cylinder produces 5497 N of push force and 3681 N of pull force. At the maximum operating pressure of 0.9 MPa, push force increases to 7068 N. The theoretical maximum force 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. A direct replacement must match the SC series dimensions, the 100 mm bore, 185 mm stroke, PT1/2 ports, and the TC centre trunnion mounting configuration. An ISO 15552 cylinder will not fit the same mounting footprint.
