About the Airtac SAI50 Standard Cylinder SAI50X50
The AirTAC SAI50X50 is a double-acting ISO 15552 profile cylinder engineered to deliver 982N of push force and 825N of pull force at 0.5MPa. Its 50mm bore and 50mm stroke create a compact, balanced motion package ideal for mid-range automation tasks. The extruded aluminum barrel design omits traditional tie rods, providing a clean exterior that simplifies mounting and maintenance.
This model features a standard carbon steel piston rod for robust structural integrity. For environments requiring high-temperature endurance up to 70C, the standard TPU seals can be upgraded to Viton (H) elastomers. Additionally, the barrel incorporates dual sensor grooves, allowing for seamless integration of CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI50 Standard Cylinder SAI50X50 Is Used
Package Diverting
Provides the 982N force needed to positively divert medium-weight packages on a high-speed sorting conveyor line.
Clamp Actuation
Extends 50mm to securely clamp workpieces in machining fixtures, holding them steady against cutting forces.
Pallet Stopping
Acts as a reliable stop gate in pallet handling systems, absorbing the momentum of incoming pallets.
Is the Airtac SAI50 Standard Cylinder SAI50X50 the Right Cylinder?
If your application requires less thrust, stepping down to the 40mm bore drops the 0.5MPa push force to 628N, whereas upgrading to the 63mm bore increases it to 1559N. At 50mm of travel, side-load stress on the rod bearing is minimal, but always ensure the load is axially aligned to prevent premature wear.
This cylinder serves as a direct replacement for any ISO 15552 profile cylinder matching the 50mm bore, 50mm stroke, and G1/4 PT port specifications. Mounting accessories like FA flanges or LB foot brackets attach directly to the standardized interface. Note that the standard adjustable air cushions decelerate the piston at stroke ends but do not lock the load; if position holding without air pressure is required, consider the SAIL variant or 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 SAI50X50 FAQ
At 0.5MPa, the SAI50X50 generates 982N of push force and 825N of pull force. If operating pressure increases to 0.7MPa, the push force rises to 1374N.
Yes, this profile cylinder is dimensionally interchangeable per ISO 15552 standards. It serves as a direct replacement for other ISO 15552 cylinders matching the 50mm bore and G1/4 port dimensions.
