About the Airtac SE125 Standard Cylinder SE125X200S
The AirTAC SE125X200S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. Utilizing a robust 125 mm bore and a 200 mm stroke, it generates a substantial 6136 N push force at 0.5 MPa and reaches a maximum output of 1252 kgf at 1.0 MPa. The integrated -S magnet enables seamless positioning feedback when paired with AirTAC CMSE or DMSE electronic sensors along the extruded body.
Built with a square extruded aluminum barrel that eliminates external tie rods, this design maintains high structural integrity while resisting corrosion and allowing flush mounting on heavy machinery. The field-adjustable pneumatic cushioning at both ends is a true deceleration mechanism, letting technicians dial in the exact damping required to soften hard end stops at high kinetic energy levels.

Where the Airtac SE125 Standard Cylinder SE125X200S Is Used
Stamping Press Feeder
Provides the 6136 N push force required to feed heavy-gauge steel coils into a mechanical stamping press, utilizing the 200 mm stroke to clear the lower die during retraction.
Injection Mold Ejection
Delivers reliable high-tonnage ejection of dense automotive plastic parts from injection molds, using the -S magnet and DMSE sensors to confirm full retraction before the mold closes.
Hydraulic Press Brake Gauging
Actuates heavy back-gauge stops on a large CNC press brake, where the 125 mm bore ensures the stopper remains rigid against heavy metal sheets without deflecting during high-force bending.
Is the Airtac SE125 Standard Cylinder SE125X200S the Right Cylinder?
Selecting the SE125X200S is appropriate when your application demands extreme linear thrust. If 6136 N at 0.5 MPa is excessive, stepping down to the 100 mm bore reduces the push force to 3927 N, which may prevent over-engineering and save air consumption. As the largest standard ISO 15552 bore in this series, there is no larger neighbor to step up to within the SE family; for loads exceeding 1252 kgf, consider deploying two cylinders in parallel. Remember that a plain SE cylinder will drift if air pressure is lost; if your load must be held statically during an exhaust or emergency stop, integrate an external BSE rod lock.
Because this model features a 200 mm stroke, the 32 mm piston rod and M27x2 thread provide significant rigidity, but any lateral side loads should still be mitigated with an external guide rail to prevent premature rod-bearing wear. The PT1/2 port ensures high volumetric flow to maintain the 30-500 mm/s operating speed across this large piston area.
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 SE125X200S FAQ
At 0.5 MPa, this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N, and the maximum push capacity is 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, the SE125X200S is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting footprint and rod thread dimensions of other standard profile cylinders. You can drop it into existing hardware using standard FA, FB, or TC mounting accessories without modifying the machine frame.
