About the Airtac SE80 Standard Cylinder SE80X125H
The AirTAC SE80X125H is a double-acting, single-rod ISO 15552 profile cylinder engineered for high-temperature actuation. Delivering a robust 2513 N push force at 0.5 MPa and a maximum thrust of 513 kgf at 1.0 MPa, it drives heavy loads with precision. The square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while resisting debris buildup.
Equipped with a Viton (FKM) seal, this specific configuration withstands operating temperatures up to 150 C, making it ideal for hot environments where standard TPU seals fail. The unit features field-adjustable pneumatic cushioning at both ends to decelerate the Ø25 mm rod smoothly over its 36 mm cushion length. Note that this SKU lacks a built-in position magnet; integrate external limit switches or select an -S variant if CMSE or DMSE sensor feedback is required.

Where the Airtac SE80 Standard Cylinder SE80X125H Is Used
Injection Mold Extraction
Handles the 2513 N push force required to pull hot plastic parts from injection molds, where the 150 C FKM Viton seal survives ambient radiated heat near the platens.
Pallet Diverting
Provides the robust 2268 N retract force needed to pivot heavy pallets on high-speed packaging conveyors, using its 125 mm stroke to clear the transport lane.
Metal Stamping Ejector
Withstands the high-temperature splash from nearby heat-treat ovens while delivering the 513 kgf max thrust to eject stamped metal blanks from progressive dies.
Is the Airtac SE80 Standard Cylinder SE80X125H the Right Cylinder?
Generating 2513 N of thrust at 0.5 MPa, this 80 mm bore fits heavy-duty cycling. If your application requires less force, stepping down to the 63 mm bore yields 1559 N of push at 0.5 MPa, saving space and air consumption. Conversely, scaling up to the 100 mm bore provides 3927 N at 0.5 MPa for heavier payloads. Because this is a standard ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders, matching the 125 mm stroke, PT3/8 port, and standard mounting footprint without hardware redesign. Remember that the adjustable air cushion only decelerates the piston near stroke end; it does not hold the load. If air pressure is lost, the rod drifts, requiring a BSE rod lock for secure positioning.
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 SE80X125H FAQ
The SE80X125H generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a maximum of 513 kgf at 1.0 MPa. It features an 80 mm bore, a 125 mm stroke, a PT3/8 port, a Ø25 mm rod with an M20x1.5 thread, and a 36 mm cushion length.
Yes, the H seal code indicates a Viton (FKM) seal rated for temperatures up to 150 C instead of the standard -20 to +70 C range. However, the adjustable air cushion only decelerates the piston near the stroke end; it is not a locking device. The rod will drift if air pressure is lost, so a BSE rod lock is required for secure load holding.
