About the Airtac SAI50 Standard Cylinder SAI50X1000S
The AirTAC SAI50X1000-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 1000mm stroke. It delivers 982N of push force at 0.5 MPa, making it suitable for traversing long linear distances in automated machinery. This specific configuration includes a magnet for proximity sensing and uses a standard carbon steel piston rod.
Because the barrel is an extruded aluminum profile, it features integrated sensor grooves on both sides. This allows you to mount CMSE or DMSE series switches directly without extra brackets. The standard seal material is TPU, but for higher ambient temperatures, a Viton (H) option is available.

Where the Airtac SAI50 Standard Cylinder SAI50X1000S Is Used
Long-Stroke Material Push
Pushes products or pallets across extended distances on a conveyor line using the full 1000mm stroke travel.
Automated Storage Retrieval
Acts as a vertical or horizontal actuator in light-duty automated storage and retrieval systems requiring 982N of force.
Large Door Actuation
Opens and closes large machine safety doors or heavy gates where a long extension is required.
Is the Airtac SAI50 Standard Cylinder SAI50X1000S the Right Cylinder?
A 50mm bore provides 982N push and 825N pull force at 0.5 MPa. If your application requires less force, stepping down to a 40mm bore yields 628N push, while moving up to a 63mm bore increases output to 1559N. This model uses PT (tapered) port threads and a G1/4 connection.
At 1000mm of stroke, the unsupported rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, use an external guide rail or a dedicated guided cylinder for heavy offset loads. Additionally, this standard cylinder does not hold position unpressurized; if your machine requires fail-safe load holding, consider the SAIL variant with an air-released lock.
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 SAI50X1000S FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982N of push force and 825N of pull force. At 0.7 MPa, the push force increases to 1374N.
The 1000mm stroke creates a long unsupported rod vulnerable to bending under side load. You should use an external guide rail or switch to a guided cylinder to protect the rod bearing.
