About the Airtac SE80 Standard Cylinder SE80BX250SH
The AirTAC SE80BX250SH is a double-acting, single-rod ISO 15552 profile cylinder engineered for rigorous duty. It delivers a robust 2513 N push force at 0.5 MPa, utilizing an 80 mm bore and a 250 mm stroke. Equipped with a SUS304 stainless steel rod and FKM Viton seals, this variant thrives in high-temperature environments up to 150 C and corrosive washdown settings.
Its square extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion. The integrated magnet (-S) supports CMSE reed and DMSE electronic position sensing, while the field-adjustable air cushioning at both ends allows you to fine-tune end-of-stroke deceleration for heavy moving loads.

Where the Airtac SE80 Standard Cylinder SE80BX250SH Is Used
Palletizer Push-Off
Drives the 250 mm stroke push-off arm on a high-speed palletizer, utilizing the 2513 N thrust to index heavy shrink-wrapped pallets while the FKM seal withstands adjacent heat-shrink tunnels.
Autoclave Door Actuator
Actuates the heavy door of a steam autoclave where the SUS304 rod and Viton seal resist 150 C moisture, while the DMSE electronic sensor confirms the locked position.
CNC Fixture Clamping
Secures large cast iron housings inside a machining center, applying 3518 N of clamping force at 0.7 MPa without tie-rods interfering with the multi-axis spindle clearance.
Is the Airtac SE80 Standard Cylinder SE80BX250SH the Right Cylinder?
Selecting this 80 mm bore provides 2513 N of push at 0.5 MPa. If your application requires less force, stepping down to the 63 mm bore yields 1559 N; conversely, scaling up to the 100 mm bore provides 3927 N. Because this model features a 250 mm stroke, the unsupported piston rod is subject to bending under lateral stress—always incorporate an external guide rail to prevent premature rod-bearing wear.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct drop-in replacement for other standard profile cylinders, matching the 80 mm bore, 250 mm stroke, PT3/8 port, and standard mounting accessories. Note that while the adjustable cushion decelerates the piston near stroke end, it does not function as a lock; a plain SE cylinder will drift if air pressure is lost, so specify a BSE rod lock variant for fail-safe load holding.
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 SE80BX250SH 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 increases to 3518 N, with a maximum push capacity of 513 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
Yes, the SE80BX250SH is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders using the same 80 mm bore, 250 mm stroke, PT3/8 ports, and standard mounting hardware. The B and H suffixes denote a SUS304 rod and FKM Viton seal for high-temp or corrosive environments.
