About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-50S
The AirTAC SAIJ63X110-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits fine-tuning of the retract end-position. With a 110 mm nominal stroke and a 50 mm adjustment screw travel, you can dial back the effective stroke anywhere within a 60-110 mm usable window. This on-machine tuning eliminates the need to swap cylinders during product changeovers.
Equipped with a SUS420J2 stainless steel rod (option A) and an integrated magnet for position sensing, it delivers 1559 N of push force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides, seamlessly accepting AirTAC CMSE reed and DMSE solid-state switches. The rear stopper solely governs travel deceleration; it is not a lock, so live air is required to hold the load.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-50S Is Used
Product Changeover Tuning
Quickly dial back the stroke from 110 mm down to 60 mm via the rear adjuster to accommodate varying package lengths on a packaging line without changing hardware.
Variable End-Stop Positioning
Ideal for operations requiring precise end-position tuning at commissioning, allowing operators to set exact retract distances within the 60-110 mm window.
Sensor-Driven Detection
The integrated -S magnet works with CMSE and DMSE sensors mounted in the dual-side barrel grooves to confirm end-of-stroke travel across the adjusted range.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-50S the Right Cylinder?
Selecting this 63 mm bore adjustable cylinder makes sense when your machine setup requires variable end-stops rather than a fixed 110 mm stroke. At 0.5 MPa it yields 1559 N push and 1402 N pull force; if your application needs less force, stepping down to a 50 mm bore drops the push force to 982 N, whereas an 80 mm bore increases it to 2513 N. Because this specific SKU carries a 50 mm adjustment code, it provides a wide 60-110 mm travel window, making it highly versatile for product-size changes on a line.
For load-holding without continuous air pressure, this standard SAIJ is insufficient as the rear adjuster acts only as a travel stop, not a brake. In such cases, consider the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder, specify a 63 mm bore, 110 mm stroke, 50 mm adjustment range, PT tapered ports, a magnet for CMSE/DMSE sensors, and SUS420J2 rod material. Note that SAIJ supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts.

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 SAIJ63AX110-50S FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 50 mm. This creates a usable travel window between 60 mm and 110 mm, enabling fine-tuning of the end position without adding external stops.
