About the Airtac SE63 Standard Cylinder SE63AX185S
The AirTAC SE63AX185S is a double-acting, single-rod ISO 15552 profile cylinder engineered to deliver a robust 1559 N push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while retaining the standardized ISO 15552 footprint for seamless retrofitting.
This specific configuration incorporates a SUS420J2 stainless steel piston rod (code A) for superior resistance to washdown and corrosive environments. Equipped with a built-in magnet (code S), the cylinder seamlessly integrates with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable pneumatic cushioning at both ends allows technicians to dial in end-stop deceleration, softening impacts during high-speed 30-800 mm/s operations.

Where the Airtac SE63 Standard Cylinder SE63AX185S Is Used
VFFS Bag Sealing
Drives the cross-sealing jaw on vertical form-fill-seal packaging lines, utilizing the 1559 N push force to consistently crimp and cut packaging films at high cycling speeds.
CNC Lathe Door Aperture
Opens and closes the sliding safety door on CNC lathes, where the SUS420J2 stainless rod withstands exposure to splashing coolant and metal chips.
Bottle Rinser Diverter
Actuates the flow diverter on an inverted bottle rinsing station, using the built-in magnet and DMSE sensors to verify gripper position in washdown environments.
Is the Airtac SE63 Standard Cylinder SE63AX185S the Right Cylinder?
Selecting the SE63X185 bore size provides 1559 N of push force at 0.5 MPa (2182 N at 0.7 MPa). If your application requires less force, stepping down to the 50 mm bore yields 982 N of push, while moving up to the 80 mm bore provides 2513 N. Keep in mind that a standard SE cylinder will drift and lose its position if air pressure drops or the valve centers; it cannot hold a load safely without live pressure. For positive holding, consider the BSE rod-lock variant or an external pilot-operated check valve.
With a 185 mm stroke and a 20 mm rod, this model is well-suited for moderate extension tasks, though any stroke of 300 mm or more on this bore requires an external guide to prevent rod-bearing bending under side loads. This unit features a PT3/8 port, a standard basic mounting interface, and the -S magnet for CMSE/DMSE sensors. It is dimensionally interchangeable with any ISO 15552 cylinder, ensuring a direct replacement that preserves your existing mounting hardware.
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 SE63AX185S FAQ
At 0.5 MPa, the SE63AX185S 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 SE63AX185S is dimensionally interchangeable per ISO 15552 standards, meaning it serves as a direct replacement for other ISO 15552 profile cylinders. It utilizes a PT3/8 port and standard mounting dimensions without requiring custom brackets.
