About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX700-50
The AirTAC SAIJ50X700-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 982N of push force at 0.5 MPa. It features a 50mm adjustment range that creates a 650-700mm usable travel window, allowing precise end-position tuning without swapping out the entire unit. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This SKU is configured with an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and PT tapered port threads. Because the 700mm stroke is relatively long, the 20mm rod diameter handles standard axial loads well, but an external guide is recommended to prevent excessive side-loading on the extended rod.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX700-50 Is Used
Product Changeover
Dial in the 650-700mm stroke window during format changes on packaging lines, fine-tuning the retract position without changing the cylinder.
Machine Setup
Perfect for commissioning long-stroke equipment where the exact end-of-travel position must be trimmed by up to 50mm on-site.
Variable End Stops
Ideal for automated assembly stations requiring flexible retraction limits to handle different part sizes on the same fixture.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX700-50 the Right Cylinder?
Choose this 50mm bore when an application requires approximately 982N of push force at 0.5 MPa, or step up to the 63mm bore if you need 1559N. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers, avoiding the need to bolt on external stops or buy a fixed-stroke SAI cylinder. It supports the standard ISO 15552 mounting interface with a reduced set of options: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
When ordering a replacement, verify the 50mm bore, 700mm stroke, 50mm adjustment, PT ports, and SUS420J2 rod material. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding without pneumatic pressure, consider an external rod lock or the SAIL/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 SAIJ50 Adjustable Cylinder SAIJ50AX700-50 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 50mm, providing a usable travel window of 650-700mm. This lets you fine-tune the end position at commissioning without adding external stops.
At 0.5 MPa operating pressure, the SAIJ50X700-50 provides 982N of push force and 825N of pull force. It can reach up to 1767N push force at 0.9 MPa.
