About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X850-100S
The AirTAC SAIJ63X850-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 1559N pull force at 0.5 MPa and uses a G3/8 port. The built-in rear stopper allows you to dial back the 850mm nominal stroke by up to 100mm, creating a precise 750-850mm usable travel window for exact end-position tuning.
This adjustable-stroke variant includes a magnet for CMSE reed and DMSE electronic sensors. Because the 850mm stroke is long, the 20mm rod and M16x1.25 thread will still need an external guide to handle side loads. The rear screw acts as a travel stop for commissioning, not a lock, so it will not hold loads without live air.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X850-100S Is Used
Changeover Adjustment
Fine-tune the 750-850mm travel window during product size changeovers without physically swapping the cylinder or adding external stops.
Long-Stroke Forming
Handles 1559N pull force for pressing or forming tasks, using the rear stopper to precisely set the retraction end position.
Automated Conveying
Uses DMSE electronic sensors to confirm long-stroke part ejection, relying on the adjuster to dial in the exact reject distance.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X850-100S the Right Cylinder?
Choose this 63mm bore when you need 1559N pull at 0.5MPa, stepping up from a 50mm bore that yields 825N. The adjustable 750-850mm window is ideal for machine changeovers where you need a variable end-stop without swapping the cylinder. If you need to step up force further, an 80mm bore provides 2268N pull.
For ISO 15552 replacement matches, specify bore 63, stroke 850, 100mm adjustment, PT tapered port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. For load-holding without live air, use an external rod lock or explore the SAIL or BSAI series instead.
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 SAIJ63X850-100S FAQ
At 0.5 MPa it provides a 1559N pull force and a 2182N push force. It can deliver up to 318 kgf at its maximum 1.0 MPa operating pressure.
The rear adjuster acts as a stopper that lets you shorten the 850mm nominal stroke by up to 100mm, resulting in a 750-850mm usable travel window. It sets the end position but does not lock the load without live air.
