About the Airtac SAI50 Standard Cylinder SAI50AX115
The AirTAC SAI50X115 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 115mm stroke. It generates 982N of push force at 0.5 MPa, making it well-suited for medium-duty handling tasks.
This unit incorporates a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. Note that the 115mm stroke is a non-standard made-to-order length, and without a magnet (-S), it cannot host reed sensors like CMSE or DMSE.

Where the Airtac SAI50 Standard Cylinder SAI50AX115 Is Used
Component Clamping
Provides reliable 982N clamping force at 0.5 MPa for securing medium-sized metal parts during machining operations.
Product Diverting
Actuates diverting arms on packaging lines to route boxes efficiently without requiring external hydraulics.
Pallet Handling
Pushes or lifts intermediate pallets within automated storage systems, utilizing its robust profile barrel design.
Is the Airtac SAI50 Standard Cylinder SAI50AX115 the Right Cylinder?
If you need less force, stepping down to a 40mm bore yields 628N at 0.5 MPa. For heavier pushing, the 63mm bore offers 1559N at 0.5 MPa. Because this 115mm stroke is a custom length, expect a made-to-order lead time.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders. To match this exact configuration, specify a 50mm bore, 115mm stroke, PT port, FA/FB flange mounting, and no magnet. Remember that a standard SAI relies on air pressure to maintain position; if your application must hold a load safely during pressure loss, consider the SAIL variant with an air-released 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.
