About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000
The AirTAC SC125X1000 is a double-acting pneumatic cylinder delivering substantial force for heavy-duty linear applications. At 0.5 MPa air pressure, it generates 6136 N pushing and 5734 N pulling, scaling up to a robust 11045 N push force at 0.9 MPa. With a 32 mm diameter piston rod and an M27x2 rod-end thread, this model is built for structural rigidity across its 1000 mm stroke.
This ISO 6430 class tie-rod cylinder features an adjustable pneumatic cushion (28 mm length) at both ends to decelerate high-inertia loads smoothly. The total extended body length is approximately 1203 mm, based on a 203 mm body length. Operating on filtered air from 0.15 to 1.0 MPa, the SC125X1000 uses standard PT ports and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000 Is Used
Palletizing & Heavy Lifting
Provides the high push force needed to lift and stack heavy pallets or engine blocks in material handling stations, operating reliably at standard shop air pressures.
Agricultural Implement Control
Controls large chutes, gates, or tillage equipment on harvesters and tractors, where the 32 mm rod withstands harsh, dusty environments and continuous cycling.
Press & Clamping Systems
Delivers up to 11045 N of clamping force for industrial presses, woodworking jigs, or metal-forming fixtures, with adjustable cushioning to protect tooling on impact.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1000 the Right Cylinder?
Select the SC125 bore when your application requires between roughly 6000 N and 11000 N of push force. If your load calculation falls closer to 4000 N, stepping down to the SC100 bore (3927 N at 0.5 MPa) can reduce air consumption and physical size. For strokes at or beyond 1000 mm, always check for potential rod buckling or side loading; the 32 mm rod on this cylinder is robust, but an external guide rail or a guided cylinder configuration is strongly recommended to protect the rod bearings from bending moments when the load is not perfectly axial.
To replace an existing unit, match five key points exactly: 125 mm bore, 1000 mm stroke, PT port thread, basic mounting (no integrated bracket), and the absence of a built-in magnet. This ensures the tie-rod dimensions, port locations, and performance align with your current AirTAC SC setup.
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 SC125X1000 FAQ
At 0.7 MPa operating pressure, the SC125X1000 generates 8590 N of push force on the piston and 5734 N of pull force on the retract stroke. The maximum theoretical force at 1.0 MPa is 1251 kgf.
This basic model (SC125X1000) ships without mounting accessories. For pivoting motion, you can order the rear single clevis (F-SC125CA) or rear double clevis (F-SC125CB) separately. For mid-body pivoting, specify the TC centre trunnion suffix, which includes the TCM1 bracket.
