About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000STC
The SC125X1000STC is a double-acting pneumatic cylinder delivering substantial force for heavy-duty linear applications. At 0.5 MPa, it generates 6136 N pushing and 5734 N pulling, scaling up to a powerful 11045 N push at the maximum operating pressure of 0.9 MPa.
This model features a 1000 mm stroke within the standard range for the 125 mm bore, which uses a robust 32 mm diameter piston rod and M27x2 rod thread. The adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-stroke, protecting the assembly from impact. It is a genuine AirTAC tie-rod cylinder, factory-equipped with a built-in magnet and centre trunnion mounting.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000STC Is Used
Pallet Transfer Systems
Moves heavy pallets or bins across roller beds in distribution centres, using the 1000 mm stroke for full lane transfers and the trunnion mount to absorb misalignment.
Press & Clamping Fixtures
Applies up to 11045 N of clamping force in woodworking or metal-forming jigs. The built-in magnet allows end-of-stroke confirmation via CMSG/DMSG sensors.
Material Lift & Tilt Mechanisms
Powers scissor lifts or hopper gates requiring a long, straight push. The centre trunnion (F-SC125TC with TCM1) lets the cylinder pivot freely during actuation.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000STC the Right Cylinder?
Select the SC125 bore when your application needs between 6136 N and 11045 N of push force; if loads are lighter, stepping down to the SC100 bore provides 3927 N at 0.5 MPa. For this 1000 mm stroke, ensure the load is guided externally if any side forces are present, as the long unsupported rod can experience bending moments.
To guarantee a correct replacement, match five key points: 125 mm bore, 1000 mm stroke, PT port thread, centre trunnion (TC) mounting with the included TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This ISO 6430 class cylinder is not dimensionally interchangeable with ISO 15552 profiles.
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 SC125X1000STC FAQ
At 0.5 MPa it provides 6136 N (push) and 5734 N (pull). 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 SC125 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centred. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve.
