About the Airtac SAI50 Standard Cylinder SAI50X145
The AirTAC SAI50X145 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 145mm stroke. It delivers a theoretical push force of 982 N at 0.5 MPa and reaches a maximum of 1767 N at 0.9 MPa. Because 145mm is not a standard catalog length, this specific 145mm stroke is manufactured as a non-standard, made-to-order configuration to suit precise travel requirements.
Built with a durable carbon steel piston rod and PT tapered port threads, this extruded aluminum barrel design includes integrated sensor grooves on both sides. While standard models support CMSE or DMSE switches, this particular unit is specified without a magnet. For environments requiring high-temperature resilience up to +70 C, TPU standard seals can be substituted with Viton (H) options.

Where the Airtac SAI50 Standard Cylinder SAI50X145 Is Used
Package Diverting
Provides the precise 145mm travel needed to actuate routing gates on packaging lines without overtravel.
Component Pressing
Generates 982 N of push force at 0.5 MPa to seat bearings or pins into housings with controlled travel.
Clamp Actuation
Drives short-stroke workholding clamps where a non-standard 145mm extension perfectly clears fixture obstructions.
Is the Airtac SAI50 Standard Cylinder SAI50X145 the Right Cylinder?
This 50mm bore provides a middle ground between the 40mm bore (628 N push at 0.5 MPa) and the 63mm bore (1559 N push at 0.5 MPa). Choose the SAI50X145 when a 40mm cylinder lacks thrust or a 63mm unit is physically too large for the machine envelope. The 145mm stroke is ideal for applications requiring exact intermediate positioning that standard 125mm or 150mm strokes cannot achieve.
Although 145mm is a relatively short stroke, if side loads are present, external guide rails will prevent rod-bearing wear. Remember that standard SAI cylinders do not hold loads pneumatically; if pressure drops, the piston drifts. For failsafe holding, specify the SAIL variant with an air-released lock or a BSAI clamp-lock cylinder. Being dimensionally interchangeable per ISO 15552, it serves as a direct replacement for other ISO 15552 profile cylinders.
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.
