About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200
The SC125X200 is a double-acting, tie-rod pneumatic cylinder with a 125 mm bore and 200 mm stroke, delivering a push force of 6136 N at 0.5 MPa and up to 11045 N at 0.9 MPa. It belongs to AirTAC's ISO 6430 class big-bore range, featuring a 32 mm piston rod with M27×2 knuckle thread and an adjustable air cushion of 28 mm at each end to decelerate the piston smoothly.
With a body length A of 203 mm, the total extended length is approximately 403 mm. The cylinder operates on filtered air at 0.15–1.0 MPa and uses PT1/2 ports. Standard TPU seals give a temperature range of -20 to +70 °C, making it a robust choice for heavy linear actuation where genuine AirTAC build quality is required.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200 Is Used
Heavy Press & Clamping
With 11045 N of thrust at 0.9 MPa, this cylinder suits large pneumatic presses, assembly jigs, and clamping fixtures where high force is needed in a compact stroke.
Material Handling Gates
The 200 mm stroke and 6136 N push at 0.5 MPa are ideal for diverting heavy packages or controlling chute gates on wide conveyor lines.
Structural Testing Rigs
ISO 6430 class construction and a robust 32 mm rod make the SC125X200 suitable for static load testing frames requiring repeatable, high-force linear actuation.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200 the Right Cylinder?
Choose the SC125X200 when your application needs around 6136 N of push force at 0.5 MPa. If you need more force, the SC160 delivers 10053 N at the same pressure; for a lighter, more compact installation, the SC100 provides 3927 N. All mounting accessories (LB foot, FA/FB flange, CA/CB clevis, TC centre trunnion) are ordered separately using the F-SC125{type} part code.
For this 200 mm stroke, side loads are generally manageable, but always avoid direct radial force on the 32 mm rod. To replace an existing cylinder, match five points exactly: 125 mm bore, 200 mm stroke, PT1/2 port thread, the specific mounting accessory, and the magnet option (this model has no built-in 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 SC125X200 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.
This specific model (SC125X200) does not include a built-in magnet. To use CMSG/DMSG/EMSG sensors, order the SC125X200-S variant, which has a magnet embedded in the piston for sensor clamping on the barrel.
