About the Airtac SAI50 Standard Cylinder SAI50X550
The AirTAC SAI50X550 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 982 N and a pull force of 825 N at 0.5 MPa. This 50mm bore, 550mm stroke configuration is well-suited for automated machinery requiring substantial reach and reliable linear motion.
Constructed with an extruded aluminum barrel, this model features standard carbon steel rod material and PT tapered port threads. Because a magnet is not specified, it operates without integrated position sensing, relying purely on mechanical travel for end-of-stroke confirmation.

Where the Airtac SAI50 Standard Cylinder SAI50X550 Is Used
Material Transfer
Ideal for pushing packages or workpieces along a 550mm transfer distance on automated packaging lines.
Long-Stroke Clamping
Provides the 982 N force needed to secure large workpieces at extended reaches within machining fixtures.
Vertical Elevation
Suitable for lifting and lowering heavy pallets or totes where a 50mm bore offers the optimal thrust balance.
Is the Airtac SAI50 Standard Cylinder SAI50X550 the Right Cylinder?
When selecting this cylinder, consider the 982 N thrust at 0.5 MPa; if your application requires less force, stepping down to a 40mm bore yields 628 N, while moving up to a 63mm bore provides 1559 N. For this 550mm stroke, long unsupported rods are susceptible to bending under side loads, so utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear.
As an ISO 15552 profile cylinder, the SAI50X550 serves as a dimensionally interchangeable direct replacement for other ISO 15552 cylinders. It utilizes a G1/4 PT port, an M16x1.5 rod thread, and is compatible with standard mounting accessories like FA flanges or TC trunnions. Note that this standard cylinder does not hold loads upon air loss; for position holding, explore 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.
