About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX150-100
The AirTAC SAIJ80X150-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 150 mm travel back by up to 100 mm. This creates a highly flexible 50-150 mm usable travel window, enabling precise end-position tuning at commissioning without swapping the cylinder or bolting on external stops.
This unit is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU lacks a magnet, adding one enables compatibility with AirTAC CMSE reed and DMSE electronic sensors. The generous 100 mm adjustment range makes it exceptionally versatile for product-size changeovers on a production line.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80AX150-100 Is Used
Machine Setup & Commissioning
Dial in the exact end-stop during initial machine commissioning, trimming the 150 mm stroke back by up to 100 mm to perfectly align tooling without machining custom spacers.
Product-Size Changeovers
Quickly adapt a packaging or assembly line for different product sizes by adjusting the cylinder travel window down to 50 mm, maximizing production line flexibility.
Variable End-Stop Positioning
Establish a precise, variable end-stop for multi-stage forming or pressing operations where the final stroke length must be fine-tuned on the fly per batch.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX150-100 the Right Cylinder?
If you need less force, stepping down to a 63 mm bore yields 1559 N, while moving up to a 100 mm bore provides 3927 N. The rear adjuster acts purely as a mechanical travel stop to decelerate the piston; it does not hold the load without live air pressure. For true load-holding without continuous air, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 150 mm nominal stroke, 100 mm adjustment range, PT G3/8 port, and your required mounting interface. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because this SKU has no magnet (-S), position sensing requires adding a magnetic piston. The 25 mm piston rod and M20x1.5 thread handle high side loads well, though long unsupported strokes still need an external guide.
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 SAIJ80 Adjustable Cylinder SAIJ80AX150-100 FAQ
An external adjusting screw at the rear acts as a mechanical stop, allowing you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 50-150 mm. The adjuster only sets the travel end and does not lock or hold the load without live air pressure.
