About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-40
The AirTAC SAIJ100X800-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 800 mm stroke with a 40 mm adjustment range, yielding a usable travel window of 760 to 800 mm for precise end-position tuning during commissioning. Equipped with a 25 mm carbon steel rod and an M20x1.5 thread, it delivers 5497 N of push force at 0.7 MPa and includes variable air cushions at both ends to protect against impact.
This model uses a G1/2 PT port and operates at speeds between 30 and 800 mm/s. The extruded aluminum barrel integrates dual sensor grooves for CMSE reed or DMSE electronic switches, though this specific SKU is configured without a magnet. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-40 Is Used
Variable End-Stop Positioning
Dial in the exact retraction point within a 760-800 mm window during machine commissioning to accommodate varying product sizes without hardware changes.
Product Changeover Systems
Quickly adjust the rear stopper on automated lines to handle different package lengths, reducing setup time between production runs.
Heavy-Duty Material Handling
Leverage the 5497 N push force at 0.7 MPa to move heavy pallets or workpieces while fine-tuning the travel end to prevent mechanical collisions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-40 the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires high thrust (5497 N at 0.7 MPa) alongside variable end-stop positioning. If you need less force, the 80 mm bore offers 3518 N at 0.7 MPa; for heavier loads, the 125 mm bore provides 8590 N. The adjustable-stroke design is ideal for machine setups requiring fine-tuning without swapping cylinders or adding external stops. Because the stroke is 800 mm, an external guide is strongly recommended to prevent excessive side-loading on the long, unsupported rod.
When specifying an ISO 15552 replacement, verify the 100 mm bore, 800 mm stroke, 40 mm adjustment range, G1/2 PT port, and the required mounting style. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series instead.
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 SAIJ100 Adjustable Cylinder SAIJ100X800-40 FAQ
It features a rear adjusting screw that allows you to mechanically shorten the effective stroke by up to 40 mm. This creates a usable travel window of 760 to 800 mm, enabling fine-tuning of the end position at commissioning without adding external stops.
At a standard operating pressure of 0.7 MPa, the SAIJ100X800-40 provides 5497 N of push force and 5497 N of pull force. It can deliver up to 7068 N of push force at 0.9 MPa.
