About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-100S
The AirTAC SAIJ63X110-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a wide 10-110 mm usable travel window from its 110 mm nominal stroke. It delivers 2182 N of push force at 0.7 MPa, matching the standard SAI thrust class for robust mid-range actuation. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for direct switching via CMSE reed or DMSE solid-state sensors.
This model uses a SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threads (G3/8). The rear adjuster acts strictly as a mechanical stop to fine-tune the retract end-position during commissioning without swapping the cylinder. It is important to note that this adjuster and the variable air cushions decelerate the load but do not hold it without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-100S Is Used
Variable End-Stop Tuning
Dial in the retract position from 10 to 110 mm on the fly, perfect for testing prototype fixture placements before finalizing a machine design.
Product-Size Changeover
Quickly adapt a packaging line to different carton lengths by adjusting the rear stopper screw rather than physically swapping out the actuator.
Assembly Machine Setup
Fine-tune the stroke end-position during initial commissioning to prevent over-travel and ensure precise component placement without external stops.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-100S the Right Cylinder?
Choose this 63 mm bore when your application requires 2182 N push force at 0.7 MPa, stepping up from a 50 mm bore that provides 1374 N, or down from an 80 mm bore delivering 3518 N. The massive 100 mm adjustment range is ideal for machines that undergo frequent product-size changeovers, allowing operators to dial in the exact end-stop without adding external physical stops. If you need to hold a load securely without continuous air pressure, this standard SAIJ will not suffice; you should select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 110 mm stroke, 100 mm adjustment, PT port thread, and -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles found in some other series.

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 SAIJ63AX110-100S FAQ
At 0.7 MPa operating pressure, this 63 mm bore cylinder provides 2182 N of push force and 1402 N of pull force. It can deliver a maximum push force of 2805 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from 110 mm down to as little as 10 mm. This creates a 10-110 mm usable window for fine-tuning the end position at commissioning without swapping cylinders.
