About the Airtac SE50 Standard Cylinder SE50X80
The AirTAC SE50X80 is a double-acting single-rod ISO 15552 profile cylinder delivering 982 N of push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames. This clean profile speeds up physical installation while maintaining the standardized ISO 15552 mounting interface.
This 50 mm bore model features a 20 mm hard-chrome piston rod, M16x1.5 rod-end thread, and a PT1/4 port. Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling. Note that this specific SKU lacks a built-in magnet, meaning it is not wired for CMSE or DMSE position sensing without modification.

Where the Airtac SE50 Standard Cylinder SE50X80 Is Used
Carton Flap Folding
Provides the 982 N push at 0.5 MPa needed to consistently fold heavy corrugated cardboard flaps on high-speed packaging lines.
Belt Diverter Arm
Uses the 80 mm stroke to push parcels onto adjacent sorting conveyors, benefiting from the smooth adjustable cushioning to stop packages gently.
Spot Welder Gun Actuation
Drives the lower electrode of a pneumatic resistance welder, where the tie-rod-free extruded barrel resists weld-spatter buildup and simplifies cleaning.
Is the Airtac SE50 Standard Cylinder SE50X80 the Right Cylinder?
Choose the SE50X80 when a task requires roughly 1000 N of extend force at 0.5 MPa. If your assembly needs less force, step down to the 40 mm bore (628 N push); if you are moving heavier jigs, step up to the 63 mm bore (1559 N push). Because this is a double-acting cylinder, it relies on continuous air pressure to move and hold the rod—air loss or a centered valve will cause the load to drift. The adjustable air cushion only decelerates the piston near stroke end; it does not lock the load. For position holding without live pressure, consider the BSE rod-lock variant or an external pilot-operated check valve. This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders using identical mounting hardware.
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 SE50X80 FAQ
At 0.5 MPa, the SE50X80 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 force is 200 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa with a speed range of 30-800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552, meaning it shares the exact mounting footprint and hardware of other ISO 15552 profile cylinders. However, this specific SKU does not have a built-in magnet, so it cannot host CMSE reed or DMSE electronic sensors unless you select a version with the -S magnet option.
