About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-40S
The AirTAC SAIJ63X1000-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 960 to 1000 mm. Delivering 2182N of push force at 0.7 MPa, it features a SUS420J2 stainless steel rod and a built-in magnet for CMSE and DMSE electronic solid-state or reed sensors. The PT tapered ports and extruded aluminum barrel with dual-side sensor grooves ensure robust, dimensionally interchangeable performance.
Because the nominal 1000 mm stroke is near the maximum standard limit for this bore, the 40 mm adjustment screw allows you to dial back the retract end-position precisely during commissioning without adding external stops. The rear adjuster acts purely as a travel stop for end-position tuning and deceleration; it does not hold the load without live air pressure. For load-holding requirements, an external rod lock or a SAIL pneumatic locking cylinder is required.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-40S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within a 960 to 1000 mm window during machine commissioning without physically swapping the cylinder or bolting on external stopper blocks.
Product Size Changeover
Quickly adapt automated machinery to new product lengths by turning the rear adjuster screw, saving setup time on production lines that run multiple SKUs.
Long-Stroke Assembly
Execute 1000 mm travel assembly or pressing tasks where the 63 mm bore provides 2182N of force, using the 40 mm adjustment to fine-tune the final end position.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-40S the Right Cylinder?
Choose this 63 mm bore cylinder when an application requires 2182N of thrust at 0.7 MPa, stepping up from a 50 mm bore that provides 1374N, or down from an 80 mm bore yielding 3518N. An adjustable-stroke model is preferred over a fixed SAI cylinder when you need fine end-position tuning at commissioning or during product changeovers. To match this exact replacement, specify a 63 mm bore, 1000 mm stroke, 40 mm adjustment range, PT port threads, and the -S magnet option.
At a 1000 mm stroke, the 20 mm rod diameter and M16x1.25 rod thread provide substantial support, but long unsupported strokes still need an external guide to prevent side-load damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Remember that the variable air cushions at both ends manage deceleration but do not function as a brake or holding device.

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 SAIJ63AX1000-40S FAQ
At 0.7 MPa operating pressure, this 63 mm bore cylinder generates 2182N of push force and 1402N of pull force. It can deliver up to 2805N push force at its maximum 0.9 MPa pressure.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 960 to 1000 mm. It functions as a mechanical stop for end-position tuning and does not lock or hold the load without continuous air pressure.
