About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X215
The SC125X215 is a double-acting pneumatic cylinder delivering a substantial 6136 N of push force at 0.5 MPa, scaling up to 11045 N at the maximum operating pressure of 0.9 MPa. Its 32 mm diameter piston rod and 28 mm adjustable air cushion are engineered to manage high-inertia loads smoothly, making it a workhorse for heavy industrial actuation.
This model features a 125 mm bore and a 215 mm stroke, with a compact tie-rod body length of 203 mm. As part of the ISO 6430 class for large bores, it operates within a speed range of 30-500 mm/s and uses a standard PT1/2 port, ensuring robust performance in demanding environments.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X215 Is Used
Heavy Press Tool Actuation
Provides the high clamping and pressing forces needed for forming, stamping, or die-casting operations, where the 11045 N push at 0.9 MPa ensures a secure hold.
Pallet Stop & Lift Stations
Ideal for end-of-line palletizing systems, using its 215 mm stroke to raise heavy pallets or activate robust mechanical stops on high-capacity conveyor lines.
Material Handling Pushers
Powerfully pushes heavy bins, boxes, or raw materials off a main line onto a gravity roller spur, leveraging its 6136 N force at standard shop air pressure.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X215 the Right Cylinder?
For applications requiring slightly less force, stepping down to a 100 mm bore reduces push force to 3927 N at 0.5 MPa. If your load demands more, the 160 mm bore offers a significant jump to 10053 N at the same pressure. Always match the cylinder's force output to the actual moving mass, not just the static load.
With a 215 mm stroke on a 32 mm rod, this cylinder is robust, but any significant side loading should be managed with an external guide rail to prevent rod bending and premature seal wear. When replacing, ensure the new unit matches all five key points: 125 mm bore, 215 mm stroke, PT1/2 port thread, basic mounting, and no magnet.
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 SC125X215 FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder of the same bore, stroke, and mounting configuration. The 125 mm bore is, however, built to the ISO 6430 class for tie-rod cylinders.
