About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X175
The SC125X175 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod family, combining a 125 mm bore with a 175 mm stroke. At 0.5 MPa air pressure it generates 6136 N of push force and 5734 N on the pull stroke, placing it in the heavy-duty force class for pressing, clamping, and lifting applications. The 32 mm diameter piston rod and 28 mm air cushion at each end provide robust guidance and smooth deceleration.
This model uses a PT1/2 port and an M27x2 rod thread, with a compact body length of 203 mm (A dimension). The SC125 bore belongs to the ISO 6430 class, rated for speeds of 30-500 mm/s, and operates on filtered air from 0.15 to 1.0 MPa. Standard TPU seals give a working temperature range of -20 to +70 °C, and the adjustable cushion lets you tune end-of-stroke impact precisely.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X175 Is Used
Heavy Press & Clamp Fixtures
With 6136 N push force at 0.5 MPa, the SC125X175 provides ample clamping pressure for welding jigs, assembly presses, and industrial holding fixtures requiring a compact 175 mm stroke.
Material Handling Pushers
Ideal for cross-belt diverters and reject stations on wide conveyors, where the 125 mm bore supplies the lateral force to move heavy packages or pallets off the line quickly.
Mould & Die Actuation
Used to operate core pulls or ejector plates in medium-to-large injection moulds, leveraging the adjustable air cushion to protect tooling during high-cycle operation.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X175 the Right Cylinder?
Choose the SC125 bore when your application needs roughly 6000 N of force at standard plant pressure. If your load is lighter, the SC100 bore delivers 3927 N push at 0.5 MPa and saves space; for heavier demands the SC160 bore steps up to 10053 N at the same pressure. Always match bore, 175 mm stroke, PT1/2 port thread, and mounting accessory when replacing an existing cylinder.
At 175 mm stroke the rod is well supported within the standard stroke range, but any side load on the 32 mm rod should be managed with an external guide or linear bearing. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders—only replace with another AirTAC SC125 of identical specifications.
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 SC125X175 FAQ
At the standard 0.5 MPa operating pressure, the push force is 6136 N and the 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.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder, so mounting dimensions and tie-rod spacing are different. Only replace with another AirTAC SC125 cylinder matching the 175 mm stroke, PT1/2 ports, and your required mounting accessories.
