About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX500-100
The AirTAC SAIJ100X500-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 500 mm travel by up to 100 mm. This yields a usable end-position window of 400 to 500 mm, letting you fine-tune machine stops at commissioning without adding external physical stops. It delivers robust thrust, pushing 7068 N at 0.9 MPa, making it well-suited for heavy-duty positioning tasks.
This SKU is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for standard CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop to set deceleration alongside the air cushions; it does not hold the load without live air pressure.

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 SAIJ100AX500-100 Is Used
Variable End-Stop Positioning
Dial in the exact 400 to 500 mm travel distance required for different part sizes on a machining line without swapping out the entire cylinder body.
Machine Setup and Changeover
Use the 100 mm adjustment screw to fine-tune the retract end-position during initial commissioning or product line changeovers, saving setup time.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX500-100 the Right Cylinder?
An adjustable-stroke cylinder is preferred over a fixed SAI model when you need variable end-stops for rapid product changeover or precise end-position tuning during machine setup. For load-holding without continuous air pressure, this cylinder is not a lock; consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 500 mm nominal stroke, 100 mm adjustment range, PT port threads, and the required mounting bracket from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Because the stroke is 500 mm, the 25 mm rod and M20x1.5 thread will carry moderate side loads, but an external guide is strongly recommended to prevent binding on long unsupported travels.
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 SAIJ100AX500-100 FAQ
At 0.5 MPa, it pushes 3927 N and pulls 3681 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 500 mm nominal stroke by up to 100 mm. This creates a usable travel window of 400 to 500 mm, allowing precise end-position tuning without external stops.
