About the Airtac SAI63 Standard Cylinder SAI63BX400S
The AirTAC SAI63X400-S is a double-acting ISO 15552 profile cylinder engineered for robust linear motion. Delivering 1559N of push force at 0.5MPa, this 63mm bore unit is tailored for demanding industrial cycles.
This specific configuration incorporates a SUS304 stainless steel piston rod for superior corrosion resistance and includes a magnet for position sensing via CMSE or DMSE switches. Tapered PT thread ports and adjustable air cushions at both ends ensure precise speed regulation upon reaching the 400mm stroke end.

Where the Airtac SAI63 Standard Cylinder SAI63BX400S Is Used
Automated Bending Press
Provides the 1559N push force at 0.5MPa required to actuate medium-duty sheet metal bending fixtures.
Pallet Diverting Arm
The 400mm stroke and integrated magnet allow precise routing of pallets on high-speed packaging lines.
Component Ejection
Utilizes adjustable end cushions to smoothly eject machined parts without damaging surface finishes.
Is the Airtac SAI63 Standard Cylinder SAI63BX400S the Right Cylinder?
If an application requires less force, stepping down to a 50mm bore yields 982N at 0.5MPa, whereas upgrading to an 80mm bore provides 2513N for heavier loads. Because this model features a 400mm stroke, external guides or a fully guided cylinder are strongly recommended to prevent rod-bearing bending under side loads.
The standard SAI design relies entirely on live air pressure to maintain its position; if pressure drops, the piston will drift. For applications requiring true load holding without continuous air, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This genuine ISO 15552 profile cylinder serves as a direct replacement for other ISO 15552 standard cylinders, sharing identical mounting interface dimensions for foot (LB), flange (FA/FB), and trunnion (TC) accessories.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI63 Standard Cylinder SAI63BX400S FAQ
At an operating pressure of 0.5MPa, this 63mm bore cylinder generates 1559N of push force and 1402N of pull force. At 0.7MPa, the push force increases to 2182N.
Yes, the SAI63X400-S is dimensionally interchangeable per ISO 15552 mounting interfaces. You can drop it in place of other ISO 15552 profile cylinders using identical mounting accessories.
