About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1370H
The AirTAC SC125X1370H is a large-bore double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa, scaling to 11045 N at the maximum operating pressure of 0.9 MPa. With a 32 mm diameter piston rod and a 28 mm adjustable air cushion, it is engineered for heavy industrial actuation where high force and heat resistance are critical.
This model is fitted with Viton (FKM) seals, designated by the 'H' suffix, shifting the operating temperature range to 0 to +150 °C for hot or chemically aggressive environments. The 1370 mm stroke is within the 1500 mm maximum standard stroke for the 125 mm bore, making this a standard-configuration cylinder ready for demanding long-reach applications.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1370H Is Used
High-Temperature Process Actuation
Viton seals allow the SC125X1370H to operate reliably in ambient temperatures up to 150°C, making it suitable for actuating dampers, valves, or clamps in ovens, autoclaves, and foundry equipment.
Heavy Machinery & Forestry
With 11045 N of force at 0.9 MPa and a robust 32 mm rod, this cylinder powers log splitters, compactors, and heavy-duty agricultural implements requiring long, powerful strokes.
Large-Format Pressing & Clamping
The 1370 mm stroke combined with high force output is ideal for large-scale pressing, laminating, or clamping fixtures where deep workpieces need consistent, controlled pneumatic pressure.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1370H the Right Cylinder?
Select the SC125 when your load requires the 6136 N push force at 0.5 MPa; if you need less force, stepping down to the SC100 bore reduces push force to 3927 N at the same pressure. For strokes of 300 mm or more, especially with a long 1370 mm extension, always assess side-loading: an unsupported rod of this length is susceptible to bending under lateral forces, so use an external linear guide or a guided cylinder to protect the rod bearings and ensure reliable operation.
To ensure a drop-in replacement, match five key points: 125 mm bore, 1370 mm stroke, PT port thread, basic (no accessory) mounting, and the absence of a magnet. This cylinder is a tie-rod design and 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 AIRTAC SC125-160 Standard Cylinder SC125X1370H FAQ
At 0.7 MPa operating pressure, the SC125 bore generates a theoretical push force of 8590 N and a pull force of 5734 N. The maximum push force at 0.9 MPa is 11045 N.
No. The SC125X1370H is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at the end of stroke to reduce impact; it is not a locking or braking device. For load holding, you must add an external mechanical lock, rod brake, or a pilot-operated check valve.
