About the Airtac SE63 Standard Cylinder SE63BX400H
The AirTAC SE63BX400H is a double-acting, single-rod ISO 15552 profile cylinder engineered for severe environments. It delivers a robust 1559 N push force at 0.5 MPa and features a SUS304 stainless steel rod alongside a Viton (FKM) seal, expanding the operating temperature range up to 150 degrees Celsius for caustic washdowns. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This 63 mm bore unit utilizes a PT3/8 port and a 20 mm rod with an M16x1.5 thread. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts when cycling at speeds up to 800 mm/s. Note that this specific SKU lacks a built-in position magnet, so it does not directly support CMSE or DMSE electronic sensors without modification.

Where the Airtac SE63 Standard Cylinder SE63BX400H Is Used
Chemical Mixing Valve Actuation
Leverages the 1559 N push force and SUS304 rod to safely open and close corrosive fluid valves in chemical processing plants.
CNC Tool Change Turrets
Uses the 400 mm stroke and FKM high-temperature seal to reliably index heavy tool turrets exposed to cutting fluid spray.
Bottling Line Diverters
Employs the adjustable air cushion to smoothly decelerate high-speed sorting gates during continuous beverage packaging runs.
Is the Airtac SE63 Standard Cylinder SE63BX400H the Right Cylinder?
Selecting this 63 mm bore provides 1559 N of thrust at 0.5 MPa. If your assembly 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. 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 fail-safe holding need a BSE rod lock variant or an external pilot-operated check valve.
At 400 mm of stroke, the unsupported piston rod is highly susceptible to bending under side loads. Implementing an external linear guide is strongly recommended to prevent premature rod-bearing wear. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other ISO 15552 profile cylinders, matching the 63 mm bore, 400 mm stroke, PT3/8 port, and standard mounting footprint without requiring custom 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 SE63BX400H 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. The absolute maximum thrust is 318 kgf when operated at the maximum rated pressure of 1.0 MPa.
No. The SE63BX400H is a standard double-acting cylinder, meaning the piston will drift downward if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston near the stroke ends; it does not act as a brake or locking mechanism. For holding loads without live pressure, consider the BSE series rod lock cylinder.
