About the Airtac SAI63 Standard Cylinder SAI63X195
The AirTAC SAI63X195 is a double-acting ISO 15552 profile barrel pneumatic cylinder featuring a 63mm bore and a 195mm stroke. It provides a push force of 1559 N and a pull force of 1402 N at 0.5 MPa operating pressure. This specific 195mm stroke is a non-standard made-to-order length, tailored for applications requiring precise intermediate travel distances beyond the standard 175mm or 200mm increments.
Built with an extruded aluminum barrel, this actuator features integrated sensor grooves on both sides for straightforward position detection. The standard configuration utilizes a carbon steel piston rod and a PT tapered port thread. For environments requiring higher temperature resistance up to 70 C, the seals can be specified in Viton (H) instead of the standard TPU material.

Where the Airtac SAI63 Standard Cylinder SAI63X195 Is Used
Custom Stroke Clamping
Ideal for specialized machining fixtures requiring a 195mm reach to clamp irregularly sized workpieces securely before a cutting operation.
Intermediate Diverting
Perfect for packaging lines that need a precise 195mm extension to divert products into specific secondary processing lanes.
Assembly Press
Delivers 1559 N of thrust at 0.5 MPa for pressing bearings or pins into housings on a semi-automated assembly stand.
Is the Airtac SAI63 Standard Cylinder SAI63X195 the Right Cylinder?
Selecting this 63mm bore makes sense when 40mm (628 N push at 0.5 MPa) is insufficient and 80mm (2513 N push at 0.5 MPa) would be physically oversized. Because the 195mm stroke is a custom length, ensure your machine envelope can accommodate the extended retracted length. This unit uses a G3/8 port and an M16x1.5 rod thread.
For applications needing position holding without continuous air pressure, a standard SAI cylinder will drift and drop; you should specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. Furthermore, while this stroke is under 300mm, if your mechanism experiences high side loads, consider utilizing external guide rails to prevent rod-bearing wear.
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 SAI63X195 FAQ
At 0.5 MPa, this 63mm bore cylinder provides 1559 N of push force and 1402 N of pull force. If operated at 0.7 MPa, the push force increases to 2182 N.
Yes, it is built to the ISO 15552 standard, making its mounting interface dimensionally interchangeable with other ISO 15552 profile cylinders. It is not a tie-rod design and uses a G3/8 PT port.
