About the Airtac SAI63 Standard Cylinder SAI63X145S
The AirTAC SAI63X145-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 145mm stroke. Because 145mm is not a standard catalog length, this unit is configured as a made-to-order stroke to fit exact machine spacing requirements. It delivers a robust 1559 N push force at 0.5 MPa and 2182 N at 0.7 MPa, making it well-suited for medium-duty actuation tasks.
This variant includes a magnetic piston (-S) for use with CMSE or DMSE reed switches, which mount directly into the extruded aluminum barrel's dual sensor grooves. The rod is constructed from standard carbon steel, and the body utilizes a PT tapered port thread to ensure a tight, reliable pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63X145S Is Used
Custom Stroke Clamping
Perfect for automated machining fixtures where a 145mm stroke precisely reaches the part without interfering with the cutting zone.
Package Diverting
Provides the exact extension needed to push packages from a main conveyor belt to a secondary sorting lane.
Gate Actuation
Ideal for opening and closing mid-sized machine safety gates or process access doors requiring a specific travel distance.
Is the Airtac SAI63 Standard Cylinder SAI63X145S the Right Cylinder?
Selecting this specific bore and stroke is ideal when a standard 150mm stroke provides too much over-travel and a 125mm stroke falls short, allowing you to match exact end-of-stroke positioning without adding external stops. If your application requires less force, stepping down to a 50mm bore yields 982 N at 0.5 MPa, whereas moving up to an 80mm bore provides 2513 N.
Because the stroke is 145mm, side-load stress on the rod bearing is minimal, but you should still ensure proper alignment to prevent premature seal wear. As a true ISO 15552 profile cylinder, this model serves as a direct replacement for any standard cylinder sharing the 63mm bore interface, utilizing a G3/8 port and standard mounting accessories like FA flanges or TC trunnions. Note that the adjustable air cushions only decelerate the piston at stroke end; they do not hold a load. If you need fail-safe position holding without air pressure, consider the SAIL locking variant or an external rod lock.
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 SAI63X145S FAQ
At a 0.5 MPa operating pressure, this 63mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X145-S is manufactured to the ISO 15552 standard, meaning its mounting dimensions and G3/8 port size are fully interchangeable with other ISO 15552 profile cylinders of the same bore size.
