About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X950-30
The AirTAC SAIJ63X950-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. With a 950 mm nominal stroke and a 30 mm adjustment range, it provides a usable travel window of 920-950 mm. This bore size delivers 1559 N of pull force at 0.5 MPa, making it robust enough for demanding industrial handling.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. The carbon steel piston rod features an M16x1.5 thread, and the PT tapered port ensures a secure pneumatic connection. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X950-30 Is Used
Long-Stroke Material Handling
Pushes or lifts products along a conveyor over a 950 mm distance, using the 30 mm adjuster to perfectly match the end-stop position to varying pallet sizes.
Machine Changeover Setup
Enables rapid reconfiguration of automated machinery for different product lengths, using the rear screw to trim the stroke back to 920 mm without changing hardware.
Assembly Line Positioning
Provides reliable linear actuation for large assembly stations, leveraging the 1559 N pull force to retract heavy tooling while fine-tuning the resting position.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X950-30 the Right Cylinder?
Choose this 63 mm bore cylinder when you need 1559 N pull force at 0.5 MPa with the flexibility to dial in a 920-950 mm travel window during commissioning. If your application requires less force, stepping down to a 50 mm bore yields 825 N of pull force. Because the 950 mm stroke is long and the rod is unsupported over much of its travel, an external guide is necessary to prevent excessive side-loading and premature seal wear.
The adjustable rear stopper allows for product changeovers without swapping the cylinder or adding external physical stops. For load-holding without continuous air pressure, this standard cylinder is insufficient; you should explore the SAIL (air-released lock) or BSAI (clamp-lock) variants instead. This model uses PT ports, a carbon steel rod, and a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ63X950-30 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm. This creates a usable travel window of 920-950 mm, allowing you to fine-tune the end position at commissioning without adding external stops.
At an operating pressure of 0.5 MPa, the SAIJ63X950-30 provides 1559 N of push force and 1402 N of pull force. At the maximum rated pressure of 1.0 MPa, it can deliver up to 318 kgf.
