About the Airtac SAI50 Standard Cylinder SAI50AX950
The AirTAC SAI50X950 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 950mm stroke. It generates 982N of push force at 0.5 MPa, making it well-suited for long-travel material handling and automated positioning tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies the mounting of proximity switches.
Built for durability in demanding environments, this specific configuration features a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance. It uses PT tapered port threads and, because a magnet is not specified, does not include sensor compatibility out of the box. For applications requiring end-position locking, the related SAIL variant offers an integrated air-released lock.

Where the Airtac SAI50 Standard Cylinder SAI50AX950 Is Used
Long-Transfer Conveying
Drives the pusher arm on a transfer line, utilizing the full 950mm stroke to shift heavy pallets between adjacent roller conveyors.
High-Reach Elevator
Raises totes to upper-tier storage tiers, using the 982N push force at 0.5 MPa to lift packaged goods against gravity.
Automated Coating Line
Moves a part-holding fixture through a 950mm dip-and-pull cycle, where the SUS420J2 stainless rod resists moisture exposure.
Is the Airtac SAI50 Standard Cylinder SAI50AX950 the Right Cylinder?
Selecting this 50mm bore model is ideal when a 40mm bore (providing 628N at 0.5 MPa) is insufficient for moving the payload, but an 80mm bore (2513N at 0.5 MPa) would be physically oversized and consume excess air. At 950mm of travel, the extended rod is highly susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder carriage is strongly recommended to prevent premature rod-bearing wear.
As a standard double-acting cylinder, the SAI50X950 relies on live air pressure to hold its position. If air is exhausted or dropped, the piston will drift; the adjustable air cushions at both ends only decelerate the piston near stroke end and do not act as a brake. This unit is dimensionally interchangeable per ISO 15552, requiring a 50mm bore, 950mm stroke, G1/4 port, and matching FA/FB flange or TC trunnion mounting accessories.
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.
