About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X90-30S
The AirTAC SAIJ63X90-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 63mm bore and a 90mm nominal stroke that can be dialed back by up to 30mm, yielding a highly versatile 60-90mm usable travel window for precise end-position tuning. This bore size delivers a robust 1559N pull force at 0.5MPa and 2182N push at 0.7MPa, making it suitable for moderate to heavy actuation tasks.
This variant includes a standard magnet for position sensing, directly compatible with AirTAC CMSE reed and DMSE electronic sensors housed within the dual-sided barrel grooves. The carbon steel piston rod features an M16x1.5 thread, and the body utilizes PT tapered ports sized at G3/8. The rear adjustment screw functions strictly as a travel stop to decelerate the stroke end, not as a load-holding lock; true position holding without live air requires a SAIL or BSAI series cylinder.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X90-30S Is Used
Machine Changeover
Dial in the 60-90mm travel window during product size transitions without replacing the cylinder or adding external mechanical stops.
Clamping Calibration
Fine-tune the retraction end-position on clamping fixtures to accommodate varying part tolerances using the rear adjustment screw.
Sensor Equipped Setup
Leverage the integrated magnet with DMSE electronic or CMSE reed switches to confirm travel endpoints across the adjusted stroke range.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X90-30S the Right Cylinder?
Select this 63mm bore adjustable cylinder when your application requires exact end-stop calibration during commissioning or frequent product changeovers, avoiding the need to physically swap out a fixed-stroke SAI unit. If your fixture demands less force, stepping down to a 50mm bore yields 825N of pull force at 0.5MPa, whereas upgrading to an 80mm bore provides 2268N for heavier payloads. The 90mm stroke is well below the side-load risk threshold, so standard mounting suffices without needing external guides.
When replacing an ISO 15552 cylinder, match these exact parameters: 63mm bore, 90mm nominal stroke, 30mm adjustment range, PT G3/8 port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations, deliberately omitting FB, CA, CB, and CR brackets to streamline the adjustable rear assembly.

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 SAIJ63X90-30S FAQ
At 0.5 MPa, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. If operated at 0.7 MPa, the push force increases to 2182N.
The rear adjuster screw allows you to shorten the 90mm nominal stroke by up to 30mm, creating a usable travel window of 60-90mm. The adjuster acts as an external stop and does not lock the load without live air pressure.
