About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-100
The AirTAC SAIJ63X160-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 60-160 mm usable travel window from its 160 mm nominal stroke. It delivers 2182 N of push force at 0.7 MPa, making it well-suited for medium-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, and the rod is constructed from SUS420J2 stainless steel for enhanced corrosion resistance.
Equipped with PT tapered port threads (G3/8) and a 20 mm rod diameter, this model handles robust duty cycles. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It does not hold the load without live air pressure; for dead-load holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-100 Is Used
Variable Product Changeover
Dial in the exact 60 to 160 mm retract position on packaging lines handling different carton sizes without physically swapping the actuator.
Machine Setup Tuning
Fine-tune the end-stop during initial commissioning to absorb mechanical tolerances and achieve precise end-of-stroke positioning.
Medium-Duty Clamping
Apply up to 2182 N of clamping force at 0.7 MPa on machining fixtures, relying on the rear stop to set the exact clamp depth.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-100 the Right Cylinder?
Choose this 63 mm bore when you need more thrust than the 50 mm bore (982 N push at 0.5 MPa) but want to avoid the larger footprint of an 80 mm cylinder. The 100 mm adjustment range is ideal for machines processing variable product sizes, allowing you to dial back the stroke by up to 100 mm on the fly instead of swapping cylinders. Mounting options include the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets. To replace an ISO 15552 cylinder, match the 63 mm bore, 160 mm stroke, 100 mm adjustment, PT G3/8 port, and desired mounting interface. Since the stroke is under 300 mm, side-load risks are moderate, but an external guide is still recommended for heavy lateral loads.
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 SAIJ63AX160-100 FAQ
At an operating pressure of 0.7 MPa, this 63 mm bore cylinder generates 2182 N of push force and 1402 N of pull force. It can reach a maximum push force of 2805 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from 160 mm down to as little as 60 mm. It sets the end position but does not lock the load without continuous air pressure.
