About the Airtac SE63 Standard Cylinder SE63BX250S
The AirTAC SE63BX250S is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding washdown and corrosive environments. It delivers a robust 1559 N push force at 0.5 MPa alongside a 1402 N pull force, making it well-suited for mid-range industrial actuation. The extruded aluminum barrel features a clean, square profile without external tie rods, which prevents contamination traps and allows for flush mounting on machinery frames.
This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and integrates a built-in magnet (code S) for position detection. The magnet interfaces directly with AirTAC CMSE reed and DMSE electronic sensors housed in the three-sided sensor grooves. Furthermore, field-adjustable pneumatic cushioning at both stroke ends allows technicians to fine-tune end-of-stroke deceleration via a set screw, effectively minimizing impact wear during high-speed 30-800 mm/s operations.

Where the Airtac SE63 Standard Cylinder SE63BX250S Is Used
Flow Wrapper Infeed
Drives the infeed pusher on a stainless food-grade flow wrapper, utilizing the 1559 N push force and SUS304 rod to withstand daily washdowns without corroding.
Pneumatic Diverter Arm
Actuates a diverting arm on a bottling line conveyor, where the 250 mm stroke provides the reach needed to lane-switch products while the DMSE sensor confirms gate position.
Lab Sample Handler
Positions sample trays in clinical diagnostic equipment, benefiting from the non-tie-rod extruded profile that prevents dust accumulation in cleanroom environments.
Is the Airtac SE63 Standard Cylinder SE63BX250S the Right Cylinder?
When sizing this actuator, consider stepping down to a 50 mm bore (982 N push at 0.5 MPa) for lighter loads or up to an 80 mm bore (2513 N push at 0.5 MPa) if your application requires greater thrust. As a standard ISO 15552 cylinder, the SE63BX250S serves as a direct replacement for any cylinder sharing the 63 mm bore, 250 mm stroke, PT3/8 port, and standardized mounting interface. To match your hardware, specify Basic, LB, or FA mounting accessories, and utilize the -S magnet with CMSE or DMSE switches. Because the 250 mm stroke generates moderate side loads on the M16x1.5 rod thread, ensure an external guide supports any heavy off-center loads to prevent rod-bearing bending.
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 SE63BX250S FAQ
The SE63BX250S generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 2182 N, with a maximum push rating of 318 kgf at 1.0 MPa. The cylinder features a PT3/8 port and a 36 mm cushion length.
No, the standard SE series is a double-acting cylinder and cannot hold a load if air is exhausted or the valve is centered; the piston will drift. The adjustable air cushion only decelerates the piston near the stroke end and does not function as a mechanical lock. For position holding, consider the BSE rod lock variant or an external pilot-operated check valve.
