About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600FA
The SC125X600FA is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). With a 32 mm diameter piston rod and a 600 mm stroke, it provides robust linear actuation for medium-to-heavy industrial tasks.
This model features an FA front rectangular flange (F-SC125FA) for secure end-face mounting. The tie-rod construction keeps the overall length compact at approximately 803 mm (body length A of 203 mm plus the 600 mm stroke). Adjustable air cushioning at both ends decelerates the piston smoothly, protecting the end caps during high-cycle operation.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600FA Is Used
Pallet Transfer
The 6136 N push force at 0.5 MPa moves heavy pallets or skids across roller conveyors, with the front flange simplifying mounting to the transfer station frame.
Press-Fit Assembly
Delivers up to 11045 N at 0.9 MPa for pressing bearings, bushings, or pins into housings. The adjustable cushion absorbs impact at the end of the 600 mm stroke.
Mold Clamping
Provides consistent clamping force for injection mold tools or die-casting fixtures. The FA flange allows direct bolting to the stationary platen.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600FA the Right Cylinder?
For applications needing more force, stepping up to the SC160 bore provides 10053 N at 0.5 MPa. If a shorter, lighter assembly is acceptable, the SC100 bore offers 3927 N at the same pressure. At a 600 mm stroke, ensure the rod is protected from side loads; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear.
When replacing an existing cylinder, match five points: 125 mm bore, 600 mm stroke, PT port thread, FA front flange mounting, and the absence of a magnet. This SC model is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders, though its 125 mm bore is an ISO 6430 class size.
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 SC125X600FA FAQ
At 0.5 MPa, push force is 6136 N and 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 SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 cylinder of the same bore and stroke. It will only directly replace another AirTAC SC tie-rod cylinder or a compatible tie-rod design with matching bore, stroke, port thread, and FA front flange mounting.
