About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200CA
The SC125X200CA 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). Its 125 mm bore and 200 mm stroke suit medium-travel clamping, pressing, and heavy-duty positioning tasks where a rear pivot mount is required.
This model includes a rear single clevis (CA) mounting, allowing the cylinder body to pivot during operation and preventing rod bending in guided load paths. With a 32 mm piston rod, M27x2 rod thread, and PT1/2 ports, it features a 28 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200CA Is Used
Heavy Machinery Articulation
Pivots dump bodies, chutes, or hopper doors on agricultural and construction equipment using the rear clevis mount for angular movement.
Pallet Stop & Lift
Raises heavy pallets or stops large packages on conveyor lines, with the clevis allowing the cylinder to swing into position without binding.
Clamping & Riveting Presses
Provides the high force (up to 11045 N) needed for pneumatic clamping, riveting, or forming operations in metal fabrication cells.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X200CA the Right Cylinder?
For higher force, step up to the 160 mm bore (10053 N at 0.5 MPa); for a lighter, faster actuator, the 100 mm bore provides 3927 N. The CA rear clevis mount (order bracket F-SC125CA) is ideal for applications where the cylinder must articulate. At 200 mm stroke, side-load risk is moderate—ensure the load is guided externally if lateral forces are present. When replacing, match bore, stroke, PT port thread, CA mounting style, and note this model has 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 SC125X200CA 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. These values assume clean, filtered air at 40 µm.
No. The SC125 is a standard double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve.
