About the Airtac SAI50 Standard Cylinder SAI50X1000
The AirTAC SAI50X1000 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 1000mm stroke. Because this stroke exceeds the standard maximum of 1200mm for this bore size, it is manufactured as a made-to-order unit. It generates 982N of push force at 0.5MPa, making it well-suited for long-travel material handling tasks.
Beyond the standard specifications, this model utilizes a carbon steel piston rod for robust structural integrity. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing for straightforward position tracking when paired with CMSE or DMSE switches. Additionally, the standard TPU seals can be swapped for Viton (H) variants if higher temperature environments are encountered.

Where the Airtac SAI50 Standard Cylinder SAI50X1000 Is Used
Long-Travel Conveying
Drives indexing mechanisms over a 1000mm distance to transfer pallets between machining stations.
Automated Assembly Lines
Extends tooling carriages across large work envelopes where 982N of push force is sufficient for the task.
Warehousing Pushers
Actuates long-stroke diverting arms to push product cases from high-speed sortation belts.
Is the Airtac SAI50 Standard Cylinder SAI50X1000 the Right Cylinder?
When sizing this actuator, consider stepping down to a 40mm bore if your application only requires 628N of push force at 0.5MPa, which can save physical space and air consumption. Conversely, if your load demands exceed 982N, stepping up to a 63mm bore yields 1559N.
Because this model features a 1000mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature wear on the rod bearing and seal, implement an external guide rail or utilize a fully guided cylinder to absorb lateral forces. Furthermore, this standard profile cylinder will drift if air pressure is lost; for applications requiring strict load holding without continuous air pressure, select the SAIL locking variant or an external pilot-operated check valve. As a dimensionally interchangeable ISO 15552 unit, it serves as a direct replacement matching the 50mm bore, 1000mm stroke, PT G1/4 port, and standard 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.
Airtac SAI50 Standard Cylinder SAI50X1000 FAQ
At 0.5MPa, this 50mm bore cylinder provides 982N of push force and 825N of pull force. At 0.7MPa, the push force increases to 1374N.
No, an unsupported 1000mm rod is prone to bending under side load. You must use an external guide rail or a guided cylinder to prevent damage to the rod bearing.
