About the Airtac SE50 Standard Cylinder SE50X650S
The AirTAC SE50X650S is a double-acting single-rod profile cylinder built to the ISO 15552 standard. It delivers 982 N of push force at 0.5 MPa and utilizes a 650 mm stroke. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush in tight machine layouts.
This unit includes a built-in magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic position sensors. Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration, softening hard impacts when cycling at speeds up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50X650S Is Used
Pallet Conveyor Diversion
Leverages the 650 mm stroke and 982 N push force to extend diverter arms on a packaging line, smoothly redirecting heavy wooden pallets onto secondary tracks.
Sheet Metal Press Feeder
Uses the 50 mm bore's 825 N pull force to retract a feeder arm, positioning cold-rolled steel sheets into a mechanical press with the precision required by ISO 15552 standards.
Vertical Goods Lift Gate
Actuates a 650 mm safety gate on a multi-tier vertical goods lift, utilizing the built-in magnet to trigger DMSE electronic sensors confirming the gate is fully open.
Is the Airtac SE50 Standard Cylinder SE50X650S the Right Cylinder?
This 50 mm bore provides 982 N push at 0.5 MPa. If your application requires less force, the neighboring 40 mm bore yields 628 N push, while stepping up to the 63 mm bore provides 1559 N push for heavier payloads. Because the stroke is 650 mm, the unsupported piston rod is highly susceptible to bending under side loads; always incorporate an external linear guide to prevent rod-bearing wear.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 profile cylinders using the standard PT1/4 port and standard mounting accessories. Note that a plain SE cylinder will drift if air pressure is lost; if the application must hold a load safely without live pressure, specify a BSE rod lock variant.
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 SE50X650S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N push and 825 N pull. At 0.7 MPa, the push force is 1374 N, with a maximum rated push of 200 kgf at 1.0 MPa. The 650 mm stroke falls within the 1200 mm maximum standard stroke limit for this bore.
No. The adjustable air cushion at both ends only decelerates the piston near the stroke ends; it is not a mechanical lock. If the air supply is exhausted, the cylinder will drift. For load-holding requirements without live pressure, use a BSE series rod lock cylinder or an external pilot-operated check valve.
