About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X160-50S
The AirTAC SAIJ63X160-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 1559N push force at 0.5MPa and features a carbon steel piston rod with an M16x1.5 thread. Because this SKU includes the -S magnet option, it is fully compatible with AirTAC CMSE reed and DMSE electronic sensors that seat directly into the dual-side extruded barrel grooves.
With a nominal 160mm stroke and a 50mm adjustment range, you get a usable travel window of 110-160mm. This built-in stopper lets you fine-tune the retract end-position during commissioning or product changeovers without swapping out the cylinder or adding external stops. The rear adjuster acts purely as a travel stop to set the end-point, not as a lock, so it will not hold a load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X160-50S Is Used
Machine Changeover
Dial in the 110-160mm travel window during product size transitions without disassembling the line or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract stroke end during commissioning to perfect seating forces, utilizing the 50mm rear adjustment screw.
Automated Forming
Leverage the 1559N push force to press or form parts, adjusting the travel on the fly for different material thicknesses.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X160-50S the Right Cylinder?
Choose this 63mm bore if you need more thrust than the 50mm bore (982N push at 0.5MPa) but less bulk than the 80mm bore (2513N). An adjustable stroke is ideal for machine setups requiring variable end-stops, whereas a fixed SAI cylinder is better for set-and-forget applications. If your process needs to hold a position without continuous air, use an SAIL air-released lock or BSAI clamp-lock instead of relying on this adjuster. To replace an ISO 15552 cylinder, match the 63mm bore, 160mm stroke, 50mm adjuster, PT tapered port, and -S magnet; mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ63X160-50S FAQ
At 0.5MPa operating pressure, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. At 0.7MPa, the push force increases to 2182N.
The rear adjuster screw lets you shorten the effective travel from the 160mm nominal stroke down to 110mm. This creates a 110-160mm usable window for fine-tuning the end position at commissioning.
