About the Airtac SE50 Standard Cylinder SE50X650
The AirTAC SE50X650 is a double-acting, single-rod ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its square extruded aluminum barrel completely eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames without protruding hardware.
This 650 mm stroke unit features field-adjustable pneumatic cushioning at both ends to precisely tune end-stop deceleration for high-speed cycling. Please note this specific SKU is configured without a built-in magnet, meaning it will not support AirTAC CMSE or DMSE position sensors out of the box.

Where the Airtac SE50 Standard Cylinder SE50X650 Is Used
Pallet Transfer Gate
Actuates a 650 mm diverter gate to redirect heavy pallets on a packaging line, utilizing the 982 N push force to overcome cart inertia.
Press Brake Tooling
Positions a backgauge stop on a CNC press brake, where the 825 N retract force reliably returns the gauge assembly for the next sheet metal bend.
Textile Beam Lifter
Raises and lowers heavy textile warp beams into processing frames, relying on the 650 mm stroke to clear the full vertical handling envelope.
Is the Airtac SE50 Standard Cylinder SE50X650 the Right Cylinder?
This 50 mm bore provides a 982 N push at 0.5 MPa, sitting neatly between the 40 mm bore (628 N push) for lighter duties and the 63 mm bore (1559 N push) for heavier loads. Because the 650 mm stroke is substantial, the unsupported piston rod is highly susceptible to bending under side loads; you must use an external guide to prevent rod-bearing damage. As a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for competing ISO 15552 cylinders, utilizing the same PT1/4 port and standard mounting accessories. Remember that the adjustable air cushion only decelerates the piston near stroke end—it will not hold a load if air pressure is lost.
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 SE50X650 FAQ
The SE50X650 generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum of 200 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
Yes, the SE50X650 is dimensionally interchangeable with any standard ISO 15552 profile cylinder, matching standard mounting interfaces and PT1/4 ports for direct retrofitting.
