About the Airtac SE63 Standard Cylinder SE63BX25S
The AirTAC SE63BX25S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 63 mm bore and a 25 mm stroke. It delivers a robust 1559 N push force at 0.5 MPa, making it well-suited for compact, high-impact actuation tasks.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance in washdown or chemically hostile environments. The extruded aluminum barrel omits external tie rods for a clean, flush-mount profile, and the integrated magnet (-S) enables precise position sensing with CMSE reed or DMSE electronic sensors.

Where the Airtac SE63 Standard Cylinder SE63BX25S Is Used
Flow Wrapper End-Sealing
Drives the high-speed sealing jaw on a continuous flow wrapper, utilizing the 1559 N push force and 25 mm stroke for precise, rapid crimping of packaging film.
Lab Sample Centrifuge Loading
Loads test tube racks into a laboratory centrifuge, where the SUS304 stainless steel rod prevents corrosion from frequent chemical splashes and sterilization cycles.
Printed Circuit Board Stamping
Actuates a short-stroke stamping head to press connectors onto PCBs, relying on the 36 mm cushion length to soften impact at high cycling speeds.
Is the Airtac SE63 Standard Cylinder SE63BX25S the Right Cylinder?
For applications requiring less force, the 50 mm bore provides 982 N push at 0.5 MPa, whereas stepping up to the 80 mm bore yields 2513 N. The field-adjustable air cushion at both ends allows you to fine-tune end-of-stroke deceleration to prevent hard mechanical impacts. Remember that the air cushion only decelerates the piston near the stroke end and does not hold loads; if position holding without live air pressure is required, consider a BSE rod lock variant. Being dimensionally interchangeable per ISO 15552, this cylinder serves as a direct replacement for other ISO 15552 cylinders, utilizing standard mounting accessories and a PT3/8 port.
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 SE63BX25S FAQ
At 0.5 MPa, the SE63BX25S provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force reaches 2182 N, with a maximum push capacity of 318 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552, meaning it shares standard mounting footprint and port sizes (PT3/8) with other ISO 15552 profile cylinders. However, it is a standard double-acting cylinder; the adjustable air cushion only decelerates the piston near stroke end and does not mechanically hold a load if air pressure is lost.
