About the Airtac SAI50 Standard Cylinder SAI50X450
The AirTAC SAI50X450 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 450mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, making it well-suited for medium-duty handling tasks. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that resists operational debris.
This specific configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because it lacks a built-in magnet, it relies purely on its mechanical cushioning for end-of-stroke deceleration rather than electronic position sensing.

Where the Airtac SAI50 Standard Cylinder SAI50X450 Is Used
Material Handling
Drives 450mm linear movements on packaging lines to push or divert medium-weight product totes.
Pallet Positioning
Indexes pallets or heavy fixtures along guided roller conveyors using its 982N thrust.
Gate Control
Actuates safety gates or machine guards requiring a long 450mm opening reach.
Is the Airtac SAI50 Standard Cylinder SAI50X450 the Right Cylinder?
Selecting this 50mm bore is ideal when you need more thrust than a 40mm bore provides (628N push at 0.5 MPa) without stepping up to the larger 63mm size (1559N). For this 450mm stroke, side-load management is critical. An unsupported rod of this length can bend under lateral forces, so mounting an external guide rail or using a guided cylinder module is strongly recommended to prevent premature seal wear.
As a true ISO 15552 profile cylinder, it serves as a direct dimensional direct replacement for other ISO 15552 cylinders. If your machinery requires intermediate stopping or fails-safe load holding during air pressure loss, note that the standard adjustable air cushions only decelerate the piston and do not lock it; you should specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead.
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 SAI50 Standard Cylinder SAI50X450 FAQ
At 0.5 MPa operating pressure, the SAI50X450 provides a push force of 982N and a pull force of 825N. If pressure is increased to 0.7 MPa, the push force reaches 1374N.
Yes, the SAI50X450 is manufactured to the ISO 15552 standard, making its mounting dimensions interchangeable with other ISO 15552 profile cylinders. You can use standard FA/FB flanges or TC trunnion accessories for installation.
