About the Airtac SE63 Standard Cylinder SE63BX125S
The AirTAC SE63BX125S is a double-acting ISO 15552 profile cylinder engineered for demanding environments. It delivers a robust 1559 N push force at 0.5 MPa, utilizing a 63 mm bore and a 125 mm stroke. The SUS304 stainless steel piston rod provides superior corrosion resistance, making the unit highly suitable for washdown or chemically exposed settings.
This model features a square extruded aluminum barrel without external tie rods, yielding a compact footprint that mounts flush against machine frames. Equipped with a built-in magnet (code S), it supports direct mounting of CMSE reed or DMSE electronic sensors along the three integrated sensor grooves for precise position detection.

Where the Airtac SE63 Standard Cylinder SE63BX125S Is Used
Bottling Line Diverters
Actuates routing gates on beverage lines where the SUS304 rod withstands daily chemical washdowns and the 1559 N force easily moves fully loaded containers.
Pallet Stretch Wrappers
Raises and lowers the film carriage through a 125 mm stroke, relying on the adjustable pneumatic cushion to prevent jarring stops at the cycle endpoints.
CNC Fixture Clamping
Secures raw aluminum castings for machining, using the integrated magnet and DMSE electronic sensor to confirm clamp engagement before the spindle starts.
Is the Airtac SE63 Standard Cylinder SE63BX125S the Right Cylinder?
Selecting this 63 mm bore provides 1559 N push at 0.5 MPa. If your application requires less force, stepping down to the 50 mm bore yields 982 N push; conversely, moving up to the 80 mm bore provides 2513 N push. Because this is a plain double-acting cylinder, it cannot hold a load without live air pressure—piston drift will occur if air is lost or the valve is centered. For position-holding requirements, consider the BSE rod-lock variant or an external pilot-operated check valve.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other standard profile cylinders using identical mounting hardware. This specific configuration includes a PT3/8 port, an M16x1.5 rod thread, and a -S magnet for CMSE / DMSE sensors. The field-adjustable air cushion at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard impacts at operating speeds up to 30-800 mm/s.
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 SE63 Standard Cylinder SE63BX125S FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N, with a maximum push capacity of 318 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
Yes, its standardized ISO 15552 mounting dimensions allow it to direct replace other profile cylinders of the same bore. However, it does not hold position unpowered; the adjustable air cushion only decelerates the piston near stroke end and will not act as a brake or lock against drift.
