About the Airtac SAI63 Standard Cylinder SAI63BX100
The AirTAC SAI63X100 is a double-acting profile cylinder offering a robust 1559 N push force at 0.5 MPa. Its 100 mm stroke provides an optimal mid-range extension for medium-duty automation tasks. Built strictly to ISO 15552 dimensional standards, this extruded aluminum barrel design drops directly into existing ISO 15552 mounting interfaces without requiring modifications.
This specific configuration features a highly corrosion-resistant SUS304 stainless steel rod, making it ideal for environments with moisture or chemical exposure. It utilizes tapered PT ports and lacks a standard magnet, relying on its integrated adjustable air cushions at both ends to smoothly decelerate the piston near stroke completion.

Where the Airtac SAI63 Standard Cylinder SAI63BX100 Is Used
Medium-Duty Clamping
Provides reliable 1559 N clamping force at 0.5 MPa for holding aluminum or mild steel workpieces during CNC milling and drilling operations.
Package Diverting
Actuates a pusher arm at 30-800 mm/s to sort medium-weight cardboard cartons on a high-speed distribution conveyor line.
Material Bending
Generates sufficient thrust to actuate light-gauge sheet metal bending jigs and small press brake tooling up to 100 mm in stroke.
Is the Airtac SAI63 Standard Cylinder SAI63BX100 the Right Cylinder?
When sizing this 63 mm bore actuator, consider stepping down to a 50 mm bore if your load requires only 982 N of push force at 0.5 MPa, which saves valuable machine space and air consumption. Conversely, if your mechanism demands higher thrust, upgrading to an 80 mm bore yields 2513 N. Because this is a double-acting cylinder, it will not hold a load in place if air pressure is lost or the directional valve is centered; the piston will drift. For suspended or gravity-loaded applications that require failsafe holding, select the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead.
As a direct dimensional replacement per ISO 15552, it matches other standard profile cylinders on mounting footprints, accessory compatibility (LB, FA, TC series), and port locations. Ensure your system specifies a PT thread connection and order the -S magnet option if you need to mount DMSE or CMSE reed switches along the dual sensor grooves.
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 SAI63BX100 FAQ
At a standard operating pressure of 0.5 MPa, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. If pressure is increased to 0.7 MPa, the push force reaches 2182 N.
Yes, the SAI63X100 is dimensionally interchangeable per ISO 15552. It shares the same mounting interface, port spacing, and accessory compatibility as other standard ISO 15552 profile cylinders, allowing for a seamless direct replacement.
