About the Airtac SAI50 Standard Cylinder SAI50X170
The AirTAC SAI50X170 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 170mm stroke. It delivers a push force of 982 N at 0.5 MPa, making it well-suited for medium-duty handling tasks. The extruded aluminum barrel design eliminates tie rods while maintaining strict dimensional interchangeability with other ISO 15552 standard actuators.
This configuration features a standard carbon steel piston rod and utilizes tapered PT ports for reliable pneumatic connections. Because a magnetic piston is not specified, position sensing must be handled externally, though the barrel retains its dual-sided sensor grooves for future flexibility. The standard TPU seals provide excellent wear resistance for general industrial environments.

Where the Airtac SAI50 Standard Cylinder SAI50X170 Is Used
Component Clamping
Provides 982 N of clamping force at 0.5 MPa, ideal for securing mid-sized metal components during machining or assembly operations.
Package Diverting
The 170mm stroke offers precise linear movement for diverting moderate-weight packages or pallets along automated conveyor lines.
Material Ejection
Utilizes adjustable air cushions at both ends to smoothly eject molded or stamped parts from machinery without impact damage.
Is the Airtac SAI50 Standard Cylinder SAI50X170 the Right Cylinder?
When selecting this actuator, consider the force balance: the 50mm bore yields 982 N of push force at 0.5 MPa, while stepping down to a 40mm bore reduces this to 628 N. If your application requires higher thrust, moving up to a 63mm bore provides 1559 N. The 170mm stroke falls below the 300mm side-load threshold, but you should still ensure proper rod alignment to prevent premature bearing wear.
This model uses PT tapered ports and mounts via standard ISO 15552 accessories like FA flanges or TC trunnions. Note that a standard SAI cylinder relies on live air pressure to maintain its position; if power drops, the load will drift. For applications requiring true position holding without continuous pressure, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve.
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 SAI50X170 FAQ
At an operating pressure of 0.5 MPa, the SAI50X170 generates a push force of 982 N and a pull force of 825 N. If pressure is increased to 0.7 MPa, the push force reaches 1374 N.
Yes, the SAI50X170 is built to the ISO 15552 profile standard, making its mounting dimensions interchangeable with other ISO 15552 cylinders. You should verify that your port and rod thread specifications match your existing setup.
