About the Airtac SE80 Standard Cylinder SE80X350SFTC
The AirTAC SE80X350SFTC is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a robust 2513 N push force at 0.5 MPa and up to 3518 N at 0.7 MPa. Built with an extruded aluminum barrel that eliminates external tie rods, it offers a flush, corrosion-resistant body that simplifies mounting and reduces contamination traps in demanding environments.
This 80 mm bore, 350 mm stroke unit includes a built-in magnet for CMSE (reed) and DMSE (electronic) position sensing, paired with an FTC center trunnion mounting accessory. Field-adjustable pneumatic cushioning at both ends allows you to fine-tune end-of-stroke deceleration via a set screw, softening hard mechanical stops during high-speed 30-800 mm/s cycles.

Where the Airtac SE80 Standard Cylinder SE80X350SFTC Is Used
Pallet Conveyor Diverting
Leveraging the 2513 N push force and 350 mm stroke, this cylinder actuates heavy pallet diverters on packaging lines, while the FTC trunnion absorbs angular rod misalignment during transit.
Injection Mold Ejection
Provides reliable positive ejection of dense plastic parts from injection molds, using the built-in S magnet to trigger DMSE electronic sensors that confirm full retraction before the mold closes.
Heavy Case Sealing Press
Drives the upper sealing head on automated case sealers, where the field-adjustable air cushion precisely decelerates the 80 mm piston to prevent crushing bulky corrugated cartons at high cycle rates.
Is the Airtac SE80 Standard Cylinder SE80X350SFTC the Right Cylinder?
If your application requires less force, stepping down to the 63 mm bore yields a 1559 N push at 0.5 MPa, while moving up to the 100 mm bore provides 3927 N for heavier loads. As a standard ISO 15552 profile cylinder, this model serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standardized mounting hardware and port sizes (PT3/8) for seamless retrofits.
Because this model features a 350 mm stroke, the extended rod length increases the risk of side-load bending on the rod bearing; an external guide is recommended to prevent premature wear. Note that a plain SE cylinder does not hold its load when air is lost or exhausted—piston drift will occur. If your machine must hold a vertical load without live pressure, consider the 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 SE80 Standard Cylinder SE80X350SFTC FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force reaches 3518 N, with a maximum push capacity of 513 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, it is dimensionally interchangeable with any ISO 15552 profile cylinder, sharing the exact same mounting interface and PT3/8 port locations for easy retrofits. However, it is a double-acting cylinder and will drift if air pressure is lost; it cannot hold a load without live pressure unless paired with a BSE rod lock.
