About the Airtac SE63 Standard Cylinder SE63BX250
The AirTAC SE63BX250 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 1559 N push force at 0.5 MPa. It features a 63 mm bore and a 250 mm stroke, utilizing a PT3/8 port and a 20 mm piston rod. This specific SKU is built with a SUS304 stainless steel rod (code B), making it highly suitable for corrosive environments or strict washdown duty where standard carbon steel rods would fail.
The extruded aluminum barrel design omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts when cycling at speeds up to 800 mm/s. Note that this configuration ships without a sensor magnet, so position detection is not supported out of the box.

Where the Airtac SE63 Standard Cylinder SE63BX250 Is Used
Bottling Line Diverter
Routes heavy PET bottle cases on a packaging conveyor, utilizing the 1559 N push force and SUS304 rod to withstand frequent high-pressure washdowns.
Pallet Film Clamp
Actuates a stretch-wrap film clamping arm on an automated palletizer, where the 250 mm stroke provides the reach needed to clear pallet stringers.
Food Mixer Lid Lift
Raises and lowers the stainless steel lid of an industrial food mixer, relying on the corrosion-resistant SUS304 rod to maintain hygiene standards.
Is the Airtac SE63 Standard Cylinder SE63BX250 the Right Cylinder?
Selecting this 63 mm bore makes sense when your application requires the 1559 N push at 0.5 MPa, bridging the gap between the smaller 50 mm bore (982 N push) and the larger 80 mm bore (2513 N push). Because this is a standard double-acting cylinder, it cannot hold a load if air pressure is lost or the valve centers; the piston will drift. If your mechanism requires static holding, you must integrate an external pilot-operated check valve or pivot to the BSE rod-lock variant.
With a 250 mm stroke, the 20 mm rod and its M16x1.5 thread face increased bending moments under heavy lateral loads. Mounting an external guide rail is strongly recommended to prevent premature rod-bearing wear. Dimensionally interchangeable per ISO 15552, this unit serves as a direct replacement for other ISO 15552 cylinders, sharing standard mounting accessories like FA front flanges or LB foot brackets.
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 SE63BX250 FAQ
The SE63BX250 delivers a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. At 0.7 MPa, the push force increases to 2182 N. The maximum push force is 318 kgf at 1.0 MPa. The operating speed range is 30-800 mm/s.
This specific SKU does not include a built-in magnet, so it cannot support AirTAC CMSE or DMSE position sensors without modification. The 'B' in the model code designates a SUS304 stainless steel rod, providing superior corrosion resistance for washdown or chemically harsh environments compared to standard hard-chrome carbon steel.
