About the Airtac SE63 Standard Cylinder SE63BX400
The AirTAC SE63BX400 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 63mm bore and 400mm stroke. It delivers a robust 1559 N push force at 0.5 MPa and utilizes a PT3/8 port. Equipped with a SUS304 stainless steel piston rod (code B), this variant is specifically built for corrosive environments or washdown duty where standard carbon steel rods would fail.
Unlike traditional tie-rod cylinders, the SE series features a square extruded aluminum barrel that mounts flush without external hardware, saving valuable space. The integrated air cushions at both stroke ends are field-adjustable via a simple screw, allowing you to fine-tune deceleration and eliminate hard end-stop impacts at operating speeds up to 800 mm/s.

Where the Airtac SE63 Standard Cylinder SE63BX400 Is Used
Stainless Pouch Forming
Drives the sealing jaw on vertical form-fill-seal equipment, using its 1559 N push and SUS304 rod to withstand daily washdowns in food packaging lines.
Chemical Dispense Valve
Actuates a high-flow diverter valve in solvent distribution systems, relying on the corrosion-resistant stainless rod to survive caustic vapor exposure.
Marine Parts Transfer
Pushes machined fittings between belt stations in coastal manufacturing hubs, where the SUS304 rod prevents salt-humidity pitting over a 400mm stroke.
Is the Airtac SE63 Standard Cylinder SE63BX400 the Right Cylinder?
This 63mm bore provides 1559 N of push force at 0.5 MPa. If your application requires less force, stepping down to the 50mm bore yields 982 N, while moving up to the 80mm bore provides 2513 N for heavier loads. Because this is a standard 400mm stroke, it is a direct dimensional replacement for any ISO 15552 cylinder, matching standard mounting hardware and PT3/8 port locations. Note that this specific SKU lacks a built-in magnet (no -S code), meaning it cannot host CMSE or DMSE position sensors without modification. Additionally, at 400mm of stroke, the unsupported load can generate significant bending moments on the rod bearing; an external guide is recommended to prevent premature wear.
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 SE63BX400 FAQ
At 0.5 MPa, it provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force reaches 2182 N. The maximum rated push force is 318 kgf at 1.0 MPa.
No. The adjustable air cushions at both ends only serve to decelerate the piston near the stroke limits; they do not lock or hold the load. If pressure drops, the piston will drift. For position holding, consider a BSE rod-lock variant or an external pilot-operated check valve.
