About the Airtac SE50 Standard Cylinder SE50BX80SN
The AirTAC SE50BX80SN is a double-acting single-rod ISO 15552 profile cylinder engineered for demanding environments. It features a SUS304 stainless steel rod and an NBR seal, making it highly suitable for corrosion-resistant and washdown applications. Delivering 982 N of push force at 0.5 MPa over an 80 mm stroke, it provides reliable linear motion for medium-duty automation.
Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, flush-mounting body that resists contamination. The cylinder includes field-adjustable air cushioning at both ends to tune end-stop deceleration, and the integrated magnet supports CMSE reed and DMSE electronic position sensing.

Where the Airtac SE50 Standard Cylinder SE50BX80SN Is Used
Bottle Filling Diverters
Actuates flow diverters on beverage lines, utilizing the SUS304 rod and NBR seal to withstand daily washdowns while providing 982 N push force over 80 mm.
Case Pack Flaps
Folds corrugated cardboard flaps on case packers, where the 825 N retract force securely tucks flaps and the compact tie-rod-less barrel fits tight machine frames.
Pallet Reject Gate
Drives pneumatic reject gates on packaging conveyors, using the integrated magnet with DMSE sensors to confirm gate position at speeds up to 800 mm/s.
Is the Airtac SE50 Standard Cylinder SE50BX80SN the Right Cylinder?
When sizing this 50 mm bore actuator, evaluate stepping down to a 40 mm bore (628 N push at 0.5 MPa) for lighter loads, or up to a 63 mm bore (1559 N push at 0.5 MPa) for higher force demands. The SE50BX80SN uses a PT1/4 port and an M16x1.5 rod thread. As a standard ISO 15552 cylinder, it serves as a direct dimensional replacement for other ISO 15552 cylinders, sharing standard mounting hardware like FA front flanges or LB foot brackets. Remember that a standard double-acting cylinder drifts when air is lost; if your application requires position holding without live pressure, consider a 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 SE50BX80SN FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf at 1.0 MPa.
No, the adjustable air cushion at both ends only decelerates the piston near the stroke end; it is not a brake or lock. The cylinder will drift if air is lost or the valve is centered. For load holding, use a BSE rod lock variant or an external locking mechanism.
