About the Airtac SE50 Standard Cylinder SE50AX850
The AirTAC SE50AX850 is a double-acting single-rod ISO 15552 profile cylinder engineered for a non-standard 850 mm stroke, making it a made-to-order actuator for long-reach tasks. It delivers a theoretical push force of 982 N at 0.5 MPa and a maximum push capacity of 200 kgf at 1.0 MPa. The extruded aluminum barrel design omits external tie rods, yielding a compact, flush-mounting body that resists corrosion and simplifies fixture integration.
Equipped with a SUS420J2 stainless steel rod (option A), this unit is purpose-built for corrosive environments and washdown duty. Because this specific SKU lacks the -S magnet code, it does not support direct CMSE or DMSE position sensing without modification. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling.

Where the Airtac SE50 Standard Cylinder SE50AX850 Is Used
Long-Reach Diverters
Drives 850 mm travel diverting arms on packaging lines, utilizing the 982 N push force to redirect heavy cartons between conveyor belts.
Washdown Test Rigs
Actuates sample handling mechanisms in food-grade washdown environments, relying on the SUS420J2 stainless steel rod to resist moisture and corrosion.
Vertical Lift Gates
Raises and lowers tall access gates on automated storage systems, where the adjustable end cushions absorb the kinetic energy of heavy panels at stroke limits.
Is the Airtac SE50 Standard Cylinder SE50AX850 the Right Cylinder?
Selecting this 50 mm bore makes sense when you need 982 N of push force at 0.5 MPa. If your application requires less force, stepping down to the 40 mm bore yields 628 N of push, while stepping up to the 63 mm bore provides 1559 N, allowing you to scale precisely to the load. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other ISO 15552 cylinders, matching the 50 mm port PT1/4, Ø20 mm rod, and M16x1.5 thread interface.
Because this model features an 850 mm stroke, the extended piston rod is highly susceptible to bending under side loads; an external guide mechanism is strongly recommended to prevent rod-bearing damage. Furthermore, a plain SE cylinder cannot hold a load if air pressure is lost or the valve is centered—the piston will drift. For applications requiring position holding without live pressure, consider the BSE rod lock variant or an external pilot-operated check valve.
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 SE50 Standard Cylinder SE50AX850 FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N. The maximum push capacity is 200 kgf at 1.0 MPa. It operates at a speed range of 30-800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 cylinders with matching PT1/4 ports and M16x1.5 rod threads. However, it is a standard double-acting cylinder and will drift if air is lost; it cannot hold a load without live pressure.
