About the Airtac SE63 Standard Cylinder SE63AX85
The AirTAC SE63AX85 is a double-acting, single-rod ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Featuring a 63 mm bore and 85 mm stroke, it uses a PT3/8 port and a 20 mm piston rod threaded M16x1.5. The square extruded aluminum barrel omits external tie rods, yielding a flush exterior that resists contamination and simplifies flush mounting on machinery frames.
This specific SKU is configured with a SUS420J2 stainless steel rod (option A) for corrosive and washdown environments. Unlike a fixed rubber bumper, its integrated pneumatic cushioning at both ends is field-adjustable via a screw, allowing you to tune end-of-stroke deceleration for varying 30-800 mm/s speeds. Note that this unit lacks a built-in magnet, so it will not trigger AirTAC CMSE or DMSE position sensors without modification.

Where the Airtac SE63 Standard Cylinder SE63AX85 Is Used
Pouch Forming Press
Drives the vertical sealing jaw on a vertical form-fill-seal machine, utilizing the 1559 N push force and SUS420J2 rod to withstand daily washdowns.
Bottle Divert Gate
Actuates a routing flap on a stainless steel beverage line, where the tie-rod-free profile prevents bacterial traps and handles high-speed cycling.
Lab Centrifuge Lid
Locks and opens the safety cover on a chemical centrifuge, relying on the SUS420J2 rod for chemical resistance and the adjustable cushion to prevent hard slams.
Is the Airtac SE63 Standard Cylinder SE63AX85 the Right Cylinder?
Select this 63 mm bore if your process requires the 1559 N push at 0.5 MPa (or 2182 N at 0.7 MPa) alongside strict corrosion resistance. If you need less force, step down to the 50 mm bore which provides 982 N push at 0.5 MPa. If your load demands more, step up to the 80 mm bore delivering 2513 N push at 0.5 MPa. Because this is a standard double-acting cylinder, it will drift if air pressure is lost or the valve centers; use a BSE rod lock variant if you need strict position holding. For retrofitting, its dimensions match standard ISO 15552 mounting accessories.
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 SE63AX85 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 is 2182 N, with an absolute maximum push of 318 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s and uses a PT3/8 port.
No, the SE63AX85 is a standard double-acting cylinder and will drift if air is lost or the valve centers. The adjustable air cushion only decelerates the piston near stroke end; it does not lock the load. For true position holding, use an AirTAC BSE rod lock cylinder or an external pilot-operated check valve.
