About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-100
The AirTAC SAIJ63X150-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down from a 150 mm nominal stroke to a highly flexible 50-150 mm usable range. Delivering 1559 N of push force at 0.5 MPa and 2182 N at 0.7 MPa, it provides robust actuation for mid-scale industrial tasks.
This SKU is configured with a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and uses PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic solid-state switches if a magnet is added later.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-100 Is Used
Product Changeover Lines
Dial in the exact end-stop for different package sizes on the fly. The 50-150 mm window lets operators reconfigure actuator travel during format changes without replacing the cylinder.
Prototype Machine Setup
Perfect for R&D benches where the optimal stroke distance is unknown. The 100 mm adjustment screw allows precise tuning of the retract position during commissioning.
Variable Positioning Jigs
Provides adaptable clamping or positioning in automated welding and assembly fixtures, allowing the same actuator to handle multiple part heights.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX150-100 the Right Cylinder?
Select this 63 mm bore when your application requires a 1559 N push force 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 100 mm adjustment range is exceptionally broad, making it ideal for prototyping or production lines where the exact end-of-stroke position varies significantly between product changeovers, completely removing the need to physically swap out cylinders for different travel lengths.
Because the nominal stroke is 150 mm, an external guide is recommended to manage side loads. When matching this for an ISO 15552 replacement, specify the 63 mm bore, 150 mm stroke, 100 mm adjust, PT G3/8 port, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set. Remember that the rear adjuster acts only as a travel stop, not a lock; for fail-safe load holding without live air pressure, utilize an external pilot-operated check valve or select an AirTAC SAIL or BSAI cylinder.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAIJ63AX150-100 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw acts as a mechanical stop that trims the retract stroke. For this SAIJ63X150-100, the 150 mm nominal stroke can be dialed back by up to 100 mm, creating a usable travel window of 50 to 150 mm without changing the cylinder itself.
