About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-100S
The AirTAC SAIJ100X800-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 800mm nominal stroke by up to 100mm for a usable travel window of 700-800mm. It delivers substantial thrust, pushing 7068N at 0.9MPa and pulling 3681N at 0.5MPa, making it robust enough for heavy industrial manipulation. The extruded aluminum barrel features sensor grooves on both sides, and because this unit includes the -S magnet, it directly supports AirTAC CMSE reed and DMSE solid-state switches for precise end-position detection.
This model utilizes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It operates at speeds from 30-800mm/s and uses PT tapered G1/2 ports. The integrated adjustable air cushions at both ends decelerate the heavy 100mm bore loads smoothly, while the rear mechanical stopper handles end-position tuning during commissioning without requiring physical cylinder swaps.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-100S Is Used
Variable End-Stop Positioning
Dial in the exact 700-800mm travel distance during machine commissioning to accommodate varying workpiece lengths without physically swapping out the entire cylinder.
Product Size Changeover
Quickly adjust the retract end-position on a packaging line when switching between different carton sizes, using the 100mm adjustment screw to adapt the stroke on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-100S the Right Cylinder?
The 100mm adjustment range is ideal for production lines running mixed product sizes, allowing operators to fine-tune the 700-800mm travel window during changeovers rather than repositioning hard stops. For any 800mm stroke, you must use an external guide rail to prevent side-loading damage to the 25mm rod and M20x1.5 rod thread, as long unsupported strokes are prone to deflection.
The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure. For load-holding applications without continuous air, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. To match this exact configuration for an ISO 15552 replacement, specify: 100mm bore, 800mm stroke, 100mm adjustment, PT G1/2 port, SUS420J2 rod, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet.
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 SAIJ100AX800-100S FAQ
At an operating pressure of 0.9MPa, the push force is 7068N and the pull force is 5497N.
The rear adjusting screw acts as an external stopper, allowing you to mechanically shorten the 800mm nominal stroke by up to 100mm. This creates a usable travel window of 700-800mm, enabling fine-tuning of the retract end-position without adding external stops or changing the cylinder.
