About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-100
The AirTAC SAIJ63X190-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the travel by up to 100 mm. This creates a wide 90-190 mm usable stroke window, letting you fine-tune the retract end-position at commissioning without swapping out the barrel or adding external stops. It delivers a robust 1559 N pull force at 0.5 MPa, making it suitable for moderate-to-heavy handling tasks.
This variant is configured with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is built without a magnet for position sensing. Remember that the rear adjuster acts purely as a travel stop to work alongside the standard air cushions; it does not lock or hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-100 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance from 90 to 190 mm during machine commissioning to accommodate different material widths without changing cylinders.
Product Size Changeover
Quickly adjust the stroke end-point on packaging lines when switching between different package sizes, reducing downtime and avoiding external mechanical stops.
Assembly Positioning
Provides 1559 N of pull force at 0.5 MPa for pressing or lifting tasks where the final end-position needs on-site fine-tuning to achieve perfect alignment.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-100 the Right Cylinder?
Choose this 63 mm bore when your application requires a pull force of 1559 N at 0.5 MPa (or up to 2805 N at 0.9 MPa). If your process demands less force, stepping down to a 50 mm bore yields 825 N of pull force at 0.5 MPa, whereas moving up to an 80 mm bore provides 2268 N. The massive 100 mm adjustment range is highly valuable for machines that process varying product sizes, acting as a variable end-stop that eliminates the need for custom fixed-stroke SAI cylinders for every part changeover.
Because the nominal stroke is 190 mm, you do not need external side-load guides, but always ensure the M16x1.5 rod thread is securely coupled to handle axial loads. If your machine requires true load-holding without continuous air pressure, this plain SAIJ cylinder will not suffice; you should instead look at the SAIL (air-released lock) or BSAI (clamp-lock) variants. This model uses a PT port thread and supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-100 FAQ
The cylinder has a 190 mm nominal stroke with a 100 mm rear adjuster, giving you an adjustable usable travel window of 90 to 190 mm. You turn the rear screw to set the exact retract position without adding external stops.
At 0.5 MPa it provides 1559 N of push force and 1402 N of pull force. If you operate at 0.9 MPa, the push force increases to 2805 N.
