About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-75
The AirTAC SAIJ100X300-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 225 to 300 mm, allowing you to dial back the nominal 300 mm stroke by up to 75 mm during commissioning.
This model features a G1/2 PT tapered port and variable air cushions at both ends to manage deceleration. The extruded aluminum barrel includes sensor grooves on both sides, supporting CMSE reed and DMSE electronic switches if a magnet is specified later. The rear adjuster acts purely as a travel stop to fine-tune end positions without adding external stops.

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 SAIJ100AX300-75 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 225 and 300 mm for product-size changeovers without swapping out the entire cylinder assembly.
Machine Setup Commissioning
Fine-tune the final end-position during initial startup using the rear stopper screw, avoiding the need to bolt on external physical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-75 the Right Cylinder?
An adjustable stroke is ideal for product changeovers and variable end-stops, whereas a fixed SAI cylinder suits fixed-repeat motions. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.
Because the 300 mm stroke is long, an external guide is recommended to prevent rod side-loading. To replace an ISO 15552 cylinder, match the 100 mm bore, 300 mm stroke, 75 mm adjustment, G1/2 port, and mounting style. Note that the SAIJ adjuster and cushions do not hold loads without live air; for pilot-operated locking, consider the SAIL or BSAI series.
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 SAIJ100AX300-75 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 300 mm down to 225 mm. It trims the retract end-position without changing the cylinder, but it is a stop, not a lock, and requires live air to hold the load.
It operates at speeds between 30 and 800 mm/s.
