About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-40S
The AirTAC SAIJ63X160-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end-of-travel position without adding external stops. With a 160 mm nominal stroke and a 40 mm adjustment range, it provides a usable travel window of 120-160 mm. This specific SKU features a SUS420J2 stainless steel rod (material code A) and a built-in magnet for position sensing. It delivers a robust 1559 N push force at 0.5 MPa, scaling up to 2805 N at 0.9 MPa, making it well-suited for mid-range actuation tasks.
The rear adjuster acts purely as a mechanical stop to set the retract distance and is not a locking device. It utilizes a PT tapered port thread and includes variable air cushions at both ends to manage impact deceleration. For load-holding without live air pressure, you would need a separate SAIL or BSAI cylinder instead of relying on this adjuster.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-40S Is Used
Machine Changeover
Dial in the retract stop from 120 to 160 mm during product size transitions on a packaging line without swapping the entire cylinder.
End-Position Tuning
Fine-tune the final end-of-stroke position during commissioning to achieve exact material feeding or clamping depth.
Assembly Line Actuation
Provide reliable mid-range thrust up to 2805 N for pressing or lifting tasks while accommodating varying part dimensions.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-40S the Right Cylinder?
Choose this 63 mm bore if your application requires a push force around 1559 N at 0.5 MPa, stepping up from a 50 mm bore that provides 982 N, or down from an 80 mm bore yielding 2513 N. The adjustable stroke is ideal for machine setups requiring commissioning fine-tune capabilities or product-size changeovers, offering more flexibility than a fixed-stroke SAI cylinder. To match this ISO 15552 interchangeable replacement exactly, specify: 63 mm bore, 160 mm stroke, 40 mm adjustment, PT ports, SUS420J2 rod, and the -S magnet option.
Since the stroke is 160 mm, side loading is minimal but always ensure proper rod alignment. The integrated magnet supports AirTAC CMSE reed and DMSE electronic solid-state sensors mounted in the dual-side barrel grooves. The 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 SAIJ63AX160-40S FAQ
It delivers a push force of 1559 N and a pull force of 1402 N at 0.5 MPa, reaching up to 2805 N push at 0.9 MPa. The operational speed range for this 63 mm bore cylinder is 30-800 mm/s.
The rear adjuster screw lets you mechanically shorten the effective travel from 160 mm down to 120 mm, creating a 120-160 mm usable window. This stopper only sets the end position and does not lock the load without live air pressure.
