About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-40
The AirTAC SAIJ63X100-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 100 mm stroke that can be fine-tuned backward by up to 40 mm, creating a usable travel window of 60 to 100 mm. Delivering 1559 N of pull force at 0.5 MPa, it handles robust actuation tasks while allowing precise end-position calibration without external stops.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and PT tapered port threads on its G3/8 ports. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. While the rear adjuster sets the travel limit, it functions strictly as a stop and does not hold the load without continuous air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-40 Is Used
End-Position Calibration
Dial in the exact retract distance during machine commissioning, trimming the 100 mm stroke back by up to 40 mm to perfect component seating without adding external stopper blocks.
Product Changeover
Quickly adjust the travel window from 60 to 100 mm on packaging lines when handling different product sizes, using the rear screw to set new end-stops on the fly.
Assembly Pressing
Leverage the 1559 N pull force at 0.5 MPa for pressing operations, using the adjustable stop to control insertion depth precisely across varying material thicknesses.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-40 the Right Cylinder?
Select this 63 mm bore cylinder when an application requires variable end-stops within a 60 to 100 mm range, stepping up from a 50 mm bore that yields 825 N of pull force at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring commissioning fine-tuning or product changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder. When matching ISO 15552 replacements, confirm the 100 mm stroke, 40 mm adjustment, PT port threads, and desired mounting style.
Because the stroke is 100 mm, side-load risks are minimal, but always ensure the load is guided to prevent binding. If your process requires the load to be held mechanically without live air pressure, this cylinder is not suitable; consider an AirTAC SAIL with an air-released lock or a BSAI clamp-lock cylinder instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

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 SAIJ63AX100-40 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 40 mm. This creates a usable travel window of 60 to 100 mm, enabling fine-tuning of the end position without changing the cylinder.
At a standard operating pressure of 0.5 MPa, the SAIJ63X100-40 provides 1559 N of pull force and 2182 N of push force. It can reach a maximum push force of 2805 N at 0.9 MPa.
