About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-20S
The AirTAC SAIJ100X750-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. The integrated -20 mm adjustment mechanism creates a usable travel window between 730 and 750 mm, allowing you to dial in the exact end position without adding external stops.
This model includes a magnet for electronic DMSE or reed CMSE sensors, fitting into the dual-side sensor grooves on the extruded aluminum barrel. It utilizes PT tapered port threads and reaches speeds from 30 to 800 mm/s. The rear adjuster acts purely as a travel stop for fine-tuning during commissioning, not as a load-holding lock.

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 SAIJ100AX750-20S Is Used
Precision End-Stop Tuning
Fine-tune the retract position by up to 20 mm during machine commissioning to achieve exact product placement without machining external spacers.
Product Changeover Adjustments
Quickly adapt the 730-750 mm travel window on packaging lines when handling slightly different package sizes, reducing setup downtime.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-20S the Right Cylinder?
Choose this adjustable SAIJ variant when your machine setup requires precise end-position tuning within a 730-750 mm window, avoiding the need to physically swap cylinders for minor product changeovers. For fixed travel without adjustment, the standard SAI cylinder is the direct alternative.
Because this unit features a 750 mm stroke, the 25mm rod needs an external guide to prevent excessive side-loading and premature seal wear. Remember that the rear adjuster only sets the travel end and will not hold a load without live air pressure. For true load-holding requirements, select an SAIL or BSAI cylinder instead. This SKU uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts.
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 SAIJ100AX750-20S FAQ
The rear adjuster screw lets you shorten the nominal 750 mm stroke by up to 20 mm, providing a usable travel window of 730 to 750 mm. It acts as a mechanical stop to fine-tune the end position and does not hold the load without air pressure.
It uses a G1/2 port and operates at speeds between 30 and 800 mm/s.
