About the Airtac SE50 Standard Cylinder SE50X250SCBCR
The AirTAC SE50X250 is a double-acting single-rod profile cylinder built to ISO 15552 dimensions, delivering a push force of 982 N and a pull force of 825 N at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion. The integrated -S magnet enables direct position tracking using AirTAC CMSE reed or DMSE electronic sensors housed in the three lateral grooves.
Equipped with a 250 mm stroke, this 50 mm bore unit relies on field-adjustable pneumatic cushioning at both ends to soften end-of-stroke impacts. You can dial in the needle valves to precisely decelerate the 20 mm hard-chrome piston rod at operating speeds up to 800 mm/s. The CB double clevis mounting accessory paired with this configuration accommodates pivoting articulations without binding.

Where the Airtac SE50 Standard Cylinder SE50X250SCBCR Is Used
Pallet Diverter Arm
Uses the CB clevis to pivot a routing gate on packaging lines, relying on the 982 N push force to snap 250 mm and redirect heavy cardboard cartons smoothly.
Film Roll Tensioner
Maintains optimal web tension on a shrink-wrap machine, where the 825 N pull force and adjustable cushioning prevent sudden jerks from tearing the material.
Stamping Press Loader
Pushes metal blanks into a die set at 800 mm/s, utilizing the built-in magnet and DMSE sensor to confirm the 250 mm extension before the press cycles.
Is the Airtac SE50 Standard Cylinder SE50X250SCBCR the Right Cylinder?
Selecting this 982 N push capacity (at 0.5 MPa) makes sense when a 40 mm bore yields too little thrust (628 N) or a 63 mm bore is physically oversized (1559 N). Because the 250 mm stroke is substantial, the unsupported rod length during extension increases bending moments on the rod bearing; an external guide rail should be fitted to prevent premature side-load wear. For direct retrofits, the standardized ISO 15552 mounting interface ensures dimensional interchangeability with other profile cylinders, utilizing the PT1/4 port, M16x1.5 rod thread, and CB clevis hardware.
Note that the adjustable air cushioning only decelerates the piston near the stroke ends and does not function as a braking mechanism. If your pivoting load must remain securely held in place during a loss of air pressure or when the directional valve is centered, you must integrate an external pilot-operated check valve or transition to an AirTAC BSE rod-lock variant to prevent drifting.
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 SE50X250SCBCR FAQ
The 50 mm bore provides a push force of 982 N and a pull force of 825 N at 0.5 MPa. At 0.7 MPa, the push force is 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE50X250 is dimensionally interchangeable with any standard ISO 15552 profile cylinder. You can swap it directly using your existing mounting hardware, including the CB clevis bracket, PT1/4 ports, and M16x1.5 rod end threads.
