About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130S
The SC125X130S is a large-bore double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). Its 130 mm stroke suits medium-travel clamping and pressing operations where high force is the priority, and the 32 mm piston rod provides robust column strength.
This model includes the built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for non-contact position sensing. The adjustable air cushion (28 mm length) decelerates the piston smoothly at stroke ends, protecting tooling from impact damage.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130S Is Used
Heavy Press & Clamp
Generates over 11 kN of clamping force at full pressure, ideal for hydraulic-replacement pneumatic presses, assembly jigs, and heavy-duty workpiece holding.
Material Forming
The 32 mm rod and high thrust suit light bending, punching, and forming operations where a compact tie-rod cylinder is preferred over a mill-type cylinder.
Palletising & Lift
Used in palletisers and vertical lifts where the 6136 N push at 0.5 MPa raises heavy loads, with the adjustable cushion preventing hard stops at end of travel.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130S the Right Cylinder?
Choose the SC125 bore when the SC100's 3927 N at 0.5 MPa is insufficient for the load. If the 130 mm stroke is close to the 1500 mm maximum standard stroke for this bore, ensure the rod is externally guided to prevent bending under side loads. For a direct replacement, match five points: 125 mm bore, 130 mm stroke, PT port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
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 SC125X130S 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 reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC125X130S is a double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centred. For load holding without live pressure, you must add a pilot-operated check valve, external rod brake, or mechanical lock.
