About the Airtac SE63 Standard Cylinder SE63BX75S
The AirTAC SE63BX75S is a double-acting single-rod ISO 15552 profile cylinder engineered for rigorous motion control. It delivers a robust 1559 N push force at 0.5 MPa alongside a 1402 N pull, utilizing a 63 mm bore and 75 mm stroke. The square extruded aluminum barrel omits external tie rods, yielding a flush, corrosion-resistant body that simplifies mounting and reduces debris traps in tight machinery.
This specific configuration pairs a SUS304 stainless steel piston rod (code B) with a built-in position magnet (code S) for washdown and sensing duty. The integrated magnet interfaces directly with AirTAC CMSE reed and DMSE electronic sensors along the three-sided sensor groove. Furthermore, the field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling.

Where the Airtac SE63 Standard Cylinder SE63BX75S Is Used
Carton Flap Folding
Drives the mechanical arms that fold corrugated carton flaps at high speed, utilizing the 1559 N push force to cleanly crease heavy cardboard before taping.
Bottle Diverter Gate
Actuates stainless steel guide rails on a beverage line to sort bottles, relying on the SUS304 rod to withstand daily chemical washdowns without pitting.
CNC Lathe Chuck Actuator
Indexes the bar feeder pusher into the spindle, using the 75 mm stroke and adjustable cushioning to prevent shock loads on the machine headstock.
Is the Airtac SE63 Standard Cylinder SE63BX75S the Right Cylinder?
Selecting the SE63BX75S is optimal when your application requires around 1559 N of push force at 0.5 MPa. If your load demands less energy, stepping down to the 50 mm bore yields 982 N of push, while scaling up to the 80 mm bore provides 2513 N. Because this is a double-acting cylinder, it relies on continuous air pressure to maintain position; if your circuit loses air or the valve centers, the piston will drift and cannot hold a load. For strict position-holding requirements without live pressure, consider the BSE rod-lock variant or an external pilot-operated check valve.
As a true ISO 15552 profile cylinder, this unit provides a direct replacement for other ISO 15552 cylinders, sharing identical mounting interface dimensions and PT3/8 ports. You can reuse existing FA front flanges or LB foot brackets without redrilling. The SUS304 rod is specifically chosen for corrosive or washdown environments where a standard medium-carbon steel rod would pit, and the -S magnet ensures you can track end-of-stroke position with CMSE or DMSE switches.
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 SE63BX75S 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 operational speed range is 30-800 mm/s.
