About the Airtac SE100 Standard Air Cylinder SE100BX125H
The AirTAC SE100BX125H is a double-acting single-rod ISO 15552 profile cylinder engineered for high-temperature and corrosive environments. It delivers a substantial 3927 N push at 0.5 MPa, utilizing a 100 mm bore and a 125 mm stroke. This configuration pairs a SUS304 stainless steel rod with a Viton (FKM) seal, expanding the operating temperature range from -20 to +150 C for demanding washdown or thermal processing duties.
Built with a square extruded aluminum barrel that eliminates external tie rods, the body mounts flush against machine frames to save space and resist contamination. The field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, protecting the 25 mm rod from hard impacts. Note that this specific SKU omits the position-sensing magnet, so it operates without CMSE or DMSE electronic switches unless retrofitted.

Where the Airtac SE100 Standard Air Cylinder SE100BX125H Is Used
Thermal Processing Doors
Handles heavy oven lids using 5497 N of thrust at 0.7 MPa, with the Viton seal surviving continuous ambient heat up to 150 C.
Washdown Ejectors
Pushes large machined castings out of a wash station, relying on the SUS304 stainless rod to resist chemical corrosion and moisture.
Pallet Dispensers
Lifts and separates empty pallets on a high-speed line, using the 125 mm stroke to index the stack without external tie rods snagging debris.
Is the Airtac SE100 Standard Air Cylinder SE100BX125H the Right Cylinder?
Selecting this 100 mm bore makes sense when your application requires heavy actuation between 3927 N and 5497 N of push force. If you need to step down to lighten the payload and reduce air consumption, the 80 mm bore offers 2513 N push at 0.5 MPa. Conversely, if you require maximum thrust, stepping up to the 125 mm bore yields 6136 N push at 0.5 MPa. Because this SKU lacks a magnet, you must add external limit switches if position feedback is required.
As a true ISO 15552 profile cylinder, the SE100BX125H is dimensionally interchangeable with other ISO 15552 cylinders, allowing you to drop it into existing foot, flange, or trunnion mounts without machining. Keep in mind that the adjustable air cushion only decelerates the piston near stroke end; it is not a locking device. If your process must hold a vertical load without live air pressure, you must integrate an external pilot-operated check valve or select a BSE rod-lock variant.
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 SE100 Standard Air Cylinder SE100BX125H FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N, and the maximum push capacity is 801 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE100BX125H is dimensionally interchangeable per ISO 15552 standards. You can drop it directly into existing mounting hardware using the standard PT1/2 port and M20x1.5 rod thread, though you should confirm overall envelope dimensions from the datasheet.
