About the Airtac SE125 Standard Cylinder SE125X160SCA
The AirTAC SE125X160SCA is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty automation. It generates a substantial 6136 N of push force at 0.5 MPa (8590 N at 0.7 MPa) while utilizing a 160 mm stroke. The robust 32 mm hard-chrome piston rod and M27x2 thread ensure high mechanical integrity for transferring massive loads.
Designed with a square extruded aluminum barrel, this unit eliminates external tie rods for a flush, corrosion-resistant profile that mounts cleanly in tight spaces. The integrated -S magnet enables precise end-position detection using CMSE reed or DMSE electronic sensors. Furthermore, the field-adjustable pneumatic cushioning at both ends allows technicians to dial in deceleration rates, softening hard end stops during high-mass transfers.

Where the Airtac SE125 Standard Cylinder SE125X160SCA Is Used
Heavy Press Stamping
Drives large metal forming presses requiring 8590 N push at 0.7 MPa to deform thick sheet metal blanks.
Pivoting Dump Gates
Actuates heavy bulk-material dump gates using the CA clevis mount, managing high inertial loads during material discharge.
Pallet Lift Arms
Raises industrial palletizer lift arms where the 1252 kgf maximum output capacity securely handles substantial pack weights.
Is the Airtac SE125 Standard Cylinder SE125X160SCA the Right Cylinder?
Selecting this 125 mm bore cylinder is appropriate when your application demands up to 6136 N push at 0.5 MPa. If your load requirement is lower, stepping down to the 100 mm bore yields 3927 N push at 0.5 MPa, whereas the 125 mm is the largest standard option available in this series. The CA single clevis mount is ideal for pivoting mechanisms, but remember that a plain SE cylinder will drift and drop its load if air pressure is lost or the valve is centered; for fail-safe holding, consider the BSE rod lock variant.
When replacing an existing actuator, this model provides true ISO 15552 dimensional interchangeability, matching the 125 mm bore, 160 mm stroke, PT1/2 port, and CA mounting footprint exactly. The integrated magnet works seamlessly with AirTAC CMSE and DMSE switches. Because the stroke is 160 mm, side-load stress on the rod bearing remains moderate, though external guides are always recommended for heavy pivoting loads.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE 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 (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE125 Standard Cylinder SE125X160SCA FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa, the push force reaches 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operational speed range for this 125 mm bore is 30-500 mm/s.
No, the adjustable air cushion at both ends only decelerates the piston near the stroke end and does not act as a brake. If air is lost, the piston will drift and drop the load. For position holding without live pressure, use a BSE rod lock cylinder or an external pilot-operated check valve.
