About the Airtac SE80 Standard Cylinder SE80BX50SH
The AirTAC SE80BX50SH is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a robust 2513 N push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames. This design keeps the overall envelope clean while maintaining the standardized ISO 15552 mounting interface for seamless retrofits.
Configured for harsh environments, this specific unit features a SUS304 stainless steel rod and FKM (Viton) seals, expanding the operating temperature range from -20 to +150 C for washdown or high-heat duties. The integrated magnet (-S) enables position detection via CMSE reed or DMSE electronic sensors. Furthermore, the field-adjustable air cushioning at both ends allows technicians to dial in the exact deceleration needed to soften hard end stops at operational speeds up to 800 mm/s.

Where the Airtac SE80 Standard Cylinder SE80BX50SH Is Used
Thermoforming Press
Drives the clamping fixture on a thermoforming line, utilizing the 2513 N push force to seal heated plastic sheets securely against the mold under high ambient temperatures.
Diverting Gate Actuator
Powers a heavy-duty sorting diverter on a washdown conveyor belt, relying on the SUS304 rod and FKM seals to withstand daily chemical cleaning without degrading.
Injection Mold Ejector
Ejects dense composite parts from an injection mold, where the 50 mm short stroke delivers rapid, high-impact retraction and the adjustable cushion softens the stop.
Is the Airtac SE80 Standard Cylinder SE80BX50SH the Right Cylinder?
Selecting this 80 mm bore makes sense when an application requires substantial thrust; stepping down to a 63 mm bore drops the 0.5 MPa push force to 1559 N, while stepping up to a 100 mm bore increases it to 3927 N. The 50 mm stroke provides quick extension and retraction cycles without occupying excessive axial space. Because this is a double-acting cylinder, it does not hold its position or load if air pressure is lost or the valve is centered—the piston will drift. If your application requires true load holding without live pressure, consider the AirTAC BSE rod-lock variant or an external pilot-operated check valve. For drop-in compatibility, match the 80 mm bore, 50 mm stroke, PT3/8 port, and your required mounting accessory when sourcing.
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 SE80BX50SH 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. Thanks to the FKM (Viton) seals, it operates reliably in temperatures from -20 to +150 C, and the standard speed range is 30-800 mm/s.
Yes, the SE80BX50SH is dimensionally interchangeable per ISO 15552 / VDMA 24562 standards. You can use it as a drop-in replacement for other ISO 15552 profile cylinders, provided you match the 80 mm bore, 50 mm stroke, PT3/8 port thread, and mounting interface. The built-in magnet also allows you to mount CMSE or DMSE sensors directly into the barrel grooves.
