About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-50
The AirTAC SAIJ63X110-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 60-110 mm usable travel window by allowing you to trim up to 50 mm off the nominal 110 mm stroke. Delivering 1559 N of push force at 0.5 MPa, it handles robust actuation tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position detection.
This variant uses a SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the end position at commissioning; it does not lock or hold the load without continuous live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-50 Is Used
Machine Changeover
Quickly adapt the stroke window from 60 to 110 mm when switching production lines to different product sizes without changing hardware.
End-Position Tuning
Fine-tune the retract end-stop during commissioning to perfect part seating or clamping force without machining external stops.
Variable Assembly Stops
Adjust the travel end-point on the fly for flexible assembly stations that handle multiple component heights.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-50 the Right Cylinder?
Choose this 63 mm bore when you need higher thrust than a 50 mm cylinder (982 N push at 0.5 MPa) but less bulk than an 80 mm bore (2513 N). The 50 mm adjustment range is excellent for product changeovers, letting you dial in a new end position without swapping the cylinder or adding external stopper blocks. For fixed travel needs, a standard SAI cylinder is simpler.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 110 mm stroke, 50 mm adjustment, G3/8 PT port, and your required mounting interface. Because the stroke is 110 mm, side-load risks are moderate, but always guide the load for long unsupported travel. If you need true load-holding without air pressure, select a SAIL or BSAI cylinder instead of relying on the adjuster.
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 SAIJ63AX110-50 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. It can deliver up to 318 kgf at its maximum 1.0 MPa pressure.
The rear adjuster screw lets you mechanically shorten the effective stroke from 110 mm down to as little as 60 mm. It acts as a travel stop for end-position tuning and does not function as a load-holding brake.
