About the Airtac SE63 Standard Cylinder SE63BX70S
The AirTAC SE63BX70S is a double-acting single-rod profile cylinder built to ISO 15552 standards, delivering a robust 1559 N push force at 0.5 MPa. It features a 63 mm bore, a 70 mm stroke, and a SUS304 stainless steel rod engineered specifically for corrosive or washdown environments.
This extruded aluminum body omits external tie rods for a flush, compact footprint while integrating sensor grooves on three sides. Equipped with a built-in magnet (S code), it supports direct mounting of AirTAC CMSE reed and DMSE electronic sensors for precise end-position detection.

Where the Airtac SE63 Standard Cylinder SE63BX70S Is Used
Bottling Line Diverter
Executes 70 mm sorting strokes on high-speed beverage conveyors, using its 1559 N thrust to push glass containers laterally without stalling the line.
Chemical Washdown Gate
Leverages the SUS304 stainless rod to actuate access panels on processing tanks, enduring daily caustic washdowns without rod pitting or seal degradation.
Carton Flap Folder
Drives the mechanical arms that tuck corrugated flaps on case sealers, relying on the adjustable pneumatic cushion to soften impacts at 70 mm stroke end.
Is the Airtac SE63 Standard Cylinder SE63BX70S the Right Cylinder?
When sizing this actuator, compare its 1559 N push at 0.5 MPa against the smaller SE50 bore (982 N push) for lighter loads, or step up to the larger SE80 bore (2513 N push) if your application demands higher thrust. The SUS304 rod provides superior rust resistance over standard carbon steel, making it ideal for food processing or chemical washdowns. For direct retrofits, this ISO 15552 profile cylinder matches standard mounting dimensions and utilizes a PT3/8 port.
Because this is a standard double-acting cylinder, it will drift and cannot hold a load if air pressure is lost or the valve is centered; applications requiring dead-stop holding should utilize a BSE rod lock variant. The field-adjustable air cushion at both ends allows you to tune end-of-stroke deceleration, preventing hard mechanical impacts during high-speed cycling.
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 SE63BX70S FAQ
At 0.5 MPa, the SE63BX70S 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 operational speed range is 30-800 mm/s.
Yes, the SE63BX70S is dimensionally interchangeable with any standard ISO 15552 profile cylinder and uses a PT3/8 port. Because it includes the -S magnet, it directly accepts AirTAC CMSE reed switches and DMSE electronic sensors for position feedback.
