About the Airtac SE80 Standard Cylinder SE80BX125H
The AirTAC SE80BX125H is a double-acting single-rod ISO 15552 profile cylinder engineered for severe environments. It delivers a substantial 2513 N push force at 0.5 MPa and a 2268 N pull, making it a robust choice for heavy actuation. The extruded aluminum barrel omits external tie rods, yielding a compact, flush-mounting body that resists corrosion and simplifies fixture integration.
This specific configuration pairs a SUS304 stainless steel rod (code B) for washdown and chemical resilience with a high-temperature Viton (FKM) seal, extending the operating envelope from -20 to +150 degrees Celsius. Field-adjustable air cushions at both ends allow technicians to tune end-of-stroke deceleration, softening hard impacts at high cycling speeds. Note that this SKU lacks the -S magnet option, so it cannot host CMSE or DMSE position sensors without modification.

Where the Airtac SE80 Standard Cylinder SE80BX125H Is Used
Thermoform Press Ejection
Utilizes the 2513 N extend force and 125 mm stroke to strip heated plastic sheets from molds, where the Viton FKM seal withstands ambient radiant heat up to 150 C.
Palletizer Flap Folding
Drives a heavy mechanical linkage to fold bottom flaps on large corrugated cartons, relying on the SUS304 rod to resist moisture in humid logistics environments.
Chemical Valve Actuation
Switches large diverter valves in fluid processing lines, leveraging the corrosion-resistant stainless steel rod and the tie-rod-free extruded profile for tight cabinet spacing.
Is the Airtac SE80 Standard Cylinder SE80BX125H the Right Cylinder?
Stepping down to a 63 mm bore drops the 0.5 MPa push to 1559 N, whereas moving up to a 100 mm bore increases it to 3927 N. Use this 80 mm bore when your load falls securely within its 2513 N capability. If the application must hold a load statically without live air pressure, this cylinder will drift, so an external pilot-operated check valve or the related BSE rod-lock variant is required. For ISO 15552 retrofits, match the 125 mm stroke, PT3/8 port, and appropriate mounting hardware. At 125 mm stroke, side-load stress on the M20x1.5 rod bearing is low, but an external guide remains best practice for heavy off-center loads.
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 SE80BX125H FAQ
At 0.5 MPa it 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 standard ISO 15552 profile cylinder. This specific SKU lacks the -S magnet, so it cannot support AirTAC CMSE or DMSE electronic position sensors out of the box.
