About the Airtac SE125 Standard Cylinder SE125X200SCB
The AirTAC SE125X200SCB is a double-acting single-rod profile cylinder built to ISO 15552 dimensions, delivering a substantial 6136 N push force at 0.5 MPa. It utilizes a hard-chrome plated medium-carbon steel rod and a PT1/2 port to handle heavy-duty pneumatic positioning. The square extruded aluminum barrel omits external tie rods, yielding a flush, corrosion-resistant exterior that mounts cleanly to machine frames.
This specific configuration includes a built-in position magnet (-S) for CMSE reed or DMSE electronic sensors, paired with a CB double clevis mounting bracket for pivoting articulation. Field-adjustable air cushions at both ends allow technicians to tune end-of-stroke deceleration, softening hard impacts when moving massive loads at up to 500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X200SCB Is Used
Stamping Press Transfer
Utilizes the 6136 N extend force to actuate heavy transfer arms that move sheet metal blanks between progressive die stations.
Injection Mold Ejection
Leverages the 200 mm stroke and CB clevis to pivot a heavy rear ejection carriage, clearing large molded parts from the press.
Lumber Sorting Diverter
Deploys the massive 125 mm bore thrust to drive a pivoting gate that redirects heavy timber grades on a high-speed saw line.
Is the Airtac SE125 Standard Cylinder SE125X200SCB the Right Cylinder?
Selecting this 125 mm bore cylinder makes sense when your application requires the maximum standard thrust in the AirTAC ISO 15552 lineup, pushing 6136 N at 0.5 MPa. If you need to step down to reduce physical size and air consumption, the neighboring 100 mm bore provides 3927 N of push force at 0.5 MPa. As the largest standard bore, there is no larger neighbor in this series. The CB double clevis mount supplied here is ideal for articulating mechanisms that pivot through an arc. Remember that a plain double-acting cylinder drifts when air pressure is lost or exhausted; if your pivot mechanism must hold a load safely during an emergency stop, integrate an external BSE rod lock or pilot-operated check valve. Because this unit carries the -S magnet, you can directly mount CMSE or DMSE sensors into the barrel grooves without additional hardware.
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 SE125X200SCB FAQ
At 0.5 MPa, this 125 mm bore cylinder outputs 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force reaches 8590 N, with a maximum rated push of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, the SE125X200SCB is dimensionally interchangeable with any standard ISO 15552 profile cylinder, sharing identical mounting and port dimensions. It features field-adjustable air cushions at both ends that use a needle screw to restrict exhaust flow, decelerating the piston near stroke end to prevent hard impacts.
