About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X75
The AirTAC SC125X75 is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). With a 75 mm stroke, it suits short, powerful linear movements in compact machine envelopes.
This ISO 6430 class cylinder uses a 32 mm diameter piston rod with M27x2 male threads and PT1/2 ports. The adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-stroke, protecting tooling from impact. Body length A is 203 mm, giving a total extended length of approximately 278 mm.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X75 Is Used
Heavy Part Clamping
Generates over 6000 N of force at standard shop air for secure clamping of large weldments or castings during machining.
Press-Fit Assembly
The short 75 mm stroke and high force are ideal for pressing bearings, bushings, or pins into housings with controlled, repeatable motion.
Die Cushion Actuation
Provides consistent, adjustable force for short-travel die cushion pins in metal stamping operations, with the 28 mm cushion absorbing shock.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X75 the Right Cylinder?
For applications needing slightly less force, the SC100 bore delivers 3927 N at 0.5 MPa in a smaller footprint. If you require more force, step up to the SC160 which provides 10053 N at the same pressure. Always match bore, stroke, PT port thread, and mounting accessory when replacing an existing cylinder.
Even at this short 75 mm stroke, avoid direct side loads on the rod. If lateral forces are present, use an external guide or linear rail to prevent rod bending and premature seal wear on the 32 mm rod.
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 AIRTAC SC125-160 Standard Cylinder SC125X75 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.
This specific SC125X75 code does not include the -S magnet option, so the piston does not have a built-in magnet. To use CMSG/DMSG sensors, order the SC125X75-S variant. The standard model requires external limit switches for position sensing.
