About the Airtac SE80 Standard Cylinder SE80BX1250SH
The AirTAC SE80BX1250SH is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding environments. It delivers a robust 2513 N push force at 0.5 MPa (3518 N at 0.7 MPa) across a 1250 mm stroke. Configured with a SUS304 stainless steel rod and FKM Viton seals, it operates reliably in temperatures up to 150 C, making it ideal for corrosive washdown or high-heat industrial settings.
The extruded aluminum barrel design omits external tie rods, providing a smooth, flush-mounted body that resists debris buildup and simplifies sensor placement across three available grooves. Field-adjustable air cushions at both ends allow you to fine-tune end-of-stroke deceleration, minimizing impact wear even at the maximum 800 mm/s operating speed. Equipped with a built-in magnet (-S), it supports direct mounting of CMSE reed and DMSE electronic position switches.

Where the Airtac SE80 Standard Cylinder SE80BX1250SH Is Used
Chemical Processing Dosing
The SUS304 rod and Viton seals withstand aggressive washdowns and 150 C thermal cycles, while the 2513 N push force actuates heavy process valves in chemical plants.
Food Grade Sorter Transfer
Leveraging the 1250 mm stroke to push products between hygienic processing lines, the corrosion-resistant profile barrel prevents contaminant traps common to tie-rod designs.
High-Temp Palletizer Head
Operating near ovens, the FKM seals maintain integrity where standard rubber fails, and the built-in magnet pairs with DMSE sensors to confirm 3518 N clamping at 0.7 MPa.
Is the Airtac SE80 Standard Cylinder SE80BX1250SH the Right Cylinder?
Selecting this 80 mm bore cylinder provides 2513 N of push force at 0.5 MPa. If your application requires less force, stepping down to the 63 mm bore yields 1559 N push, while moving up to the 100 mm bore provides 3927 N push, allowing you to optimize air consumption and footprint. Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; applications requiring true position holding without live pressure should integrate an external pilot-operated check valve or evaluate the AirTAC BSE rod-lock variant.
At 1250 mm of stroke, the 25 mm rod and M20x1.5 thread experience significant leverage under side loads, which can accelerate bearing wear and induce rod bending. For this long extension length, incorporating an external guide rail is critical to prevent lateral stress. Dimensionally interchangeable with other ISO 15552 cylinders, this unit drops into existing footprints using standard PT3/8 porting and compatible 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 SE80 Standard Cylinder SE80BX1250SH FAQ
This 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force at 0.5 MPa. At 0.7 MPa, the push force is 3518 N, with an absolute maximum push of 513 kgf at 1.0 MPa. The 1250 mm stroke is within the 1500 mm maximum standard stroke limit for this bore size.
No, the field-adjustable air cushions at both ends only decelerate the piston near the stroke ends to soften impacts; they do not lock or hold the load when air is removed. The integrated -S magnet is specifically designed to trigger AirTAC CMSE reed switches and DMSE solid-state electronic sensors mounted in the barrel grooves for precise position detection.
