About the Airtac SC125-160 Standard Cylinder SC125X80S
The SC125X80S is a double-acting pneumatic cylinder delivering 6136 N push force at 0.5 MPa (11045 N at 0.9 MPa) from a 125 mm bore. With an 80 mm stroke and a 32 mm piston rod, it suits short-throw, high-force clamping or pressing tasks where space is tight.
This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG sensors to mount directly on the tie-rod barrel for reliable end-of-stroke detection. The adjustable air cushion (28 mm length) decelerates the piston smoothly, and the PT1/2 port thread connects to standard pneumatic fittings.

Where the Airtac SC125-160 Standard Cylinder SC125X80S Is Used
Heavy-Duty Clamping
Generates over 11000 N at full pressure for secure workpiece holding in machining centres and welding fixtures.
Press-Fit Assembly
The 80 mm stroke and high force insert bearings, bushings, or pins with controlled, repeatable motion.
Material Stops & Gates
Magnetic piston sensors confirm the raised or lowered position of heavy-duty stops on conveyor lines.
Is the Airtac SC125-160 Standard Cylinder SC125X80S the Right Cylinder?
For applications needing less force, step down to the SC100 bore (3927 N at 0.5 MPa). If you require a pivoting mount, the SC125X80S can be ordered with a rear clevis (CA/CB) or centre trunnion (TC) instead of the basic configuration. When replacing an existing cylinder, match five points: 125 mm bore, 80 mm stroke, PT1/2 port thread, the -S magnet for sensor compatibility, and the mounting style. This SC series is a tie-rod cylinder; it is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC125-160 Standard Cylinder SC125X80S FAQ
At 0.5 MPa, push force is 6136 N and pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix in SC125X80S indicates a built-in magnet on the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped directly onto the cylinder barrel for position feedback.
