About the Airtac SAI50 Standard Cylinder SAI50X750S
The AirTAC SAI50X750-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 750mm stroke. It delivers a thrust of 982 N at 0.5 MPa, making it well-suited for long-travel material handling and robust actuation tasks. The extruded aluminum barrel design eliminates tie rods, providing a clean exterior that simplifies cleaning and maintenance.
This specific configuration includes a magnet for use with CMSE and DMSE sensor switches, which ride securely in the dual grooves machined into the cylinder barrel. The standard carbon steel piston rod offers dependable durability for general industrial automation, while the adjustable air cushions at both ends ensure smooth end-of-stroke deceleration over this extended 750mm travel.

Where the Airtac SAI50 Standard Cylinder SAI50X750S Is Used
Extended Material Transfer
Drives long-stroke pusher arms on packaging and sorting lines, moving products smoothly across 750mm of travel with 982 N of force at 0.5 MPa.
Automated Assembly Line
Actuates large-format component placement or fixture shuttles, utilizing the integrated magnet and CMSE sensors for precise end-position confirmation.
Pallet Handling System
Indexes pallets or heavy totes along extended roller conveyors, relying on the robust carbon steel rod and adjustable air cushions to absorb dynamic loads.
Is the Airtac SAI50 Standard Cylinder SAI50X750S the Right Cylinder?
When configuring long-travel actuators, stepping up to the 63mm bore yields a higher 0.5 MPa push force of 1559 N if your application demands greater thrust, or dropping down to the 40mm bore provides 628 N for lighter, space-constrained setups. For a 750mm stroke, side load is a primary concern; unsupported rods of this length are prone to bending under lateral loads. To prevent premature seal wear and rod bearing failure, mount external guide rails or select a guided cylinder module.
This SAI50X750-S utilizes a PT tapered G1/4 port and supports standard ISO 15552 mounting accessories like FA/FB flanges or TC trunnions. As a double-acting cylinder, it relies on live air pressure to hold its position; if pneumatic supply is lost or the valve is centered, the piston will drift. For applications requiring true position holding without constant air pressure, consider integrating an external pilot-operated check valve or upgrading to the SAIL pneumatic lock variant.
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 SAI50X750S FAQ
At 0.5 MPa operating pressure, the SAI50X750-S provides 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 SAI50X750-S is dimensionally interchangeable per ISO 15552 standards. It serves as a direct replacement for other ISO 15552 profile cylinders, provided you match the 50mm bore, 750mm stroke, and G1/4 port size.
