About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-10
The AirTAC SAIJ63X1000-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that permits up to 10 mm of end-position trimming. This yields a usable travel window of 990 to 1000 mm, enabling precise calibration without external stops. The extruded aluminum barrel integrates sensor grooves on three sides for straightforward position feedback. Equipped with a SUS420J2 stainless steel rod and PT tapered ports, it delivers 1402 N of pull force at 0.5 MPa and 2182 N of push force at 0.7 MPa.
Because the adjuster functions strictly as a mechanical stop and not a locking mechanism, the cylinder cannot hold loads without continuous live air pressure. For applications requiring secure position retention in the event of air loss, consider the SAIL or BSAI series. The standard variable air cushions at both ends manage deceleration, while the 20 mm rod and M16x1.5 thread provide robust resistance to side loads inherent in long-stroke setups.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-10 Is Used
Machine Setup Calibration
Dial in the exact end-of-stroke position during initial commissioning without swapping out the entire cylinder or adding external stopper blocks.
Product Changeover
Quickly adjust the travel window down by 10 mm when running a slightly shorter product variant on a packaging or handling line.
Long-Stroke Assembly
Handle extended reach pushing operations with 1559 N force at 0.5 MPa while relying on the rear stopper for final positioning tweaks.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-10 the Right Cylinder?
Selecting this 63 mm bore model makes sense when your application requires the 1559 N push force at 0.5 MPa, stepping up from the 50 mm bore which provides 982 N. The adjustable 990 to 1000 mm travel window is ideal for machine setups requiring exact end-position tuning during commissioning or product changeover, offering flexibility that a fixed-stroke SAI cylinder cannot match. To replace an ISO 15552 cylinder, match the 63 mm bore, 1000 mm stroke, 10 mm adjustment, PT port thread, and Basic/LB/TC mounting interface.
At a 1000 mm stroke, the unsupported rod length increases susceptibility to bending and side loads. Implementing an external guide rail is strongly recommended to prevent premature seal wear. The rear adjuster screw acts solely as a travel stop; it does not function as a brake or lock for load holding. If your setup requires true load holding without live air pressure, explore the SAIL or BSAI clamp-lock series instead.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ63AX1000-10 FAQ
The 63 mm bore generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. 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 10 mm, creating a 990 to 1000 mm usable travel window for fine-tuning the end position without changing the cylinder.
