About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-100S
The AirTAC SAIJ63X170-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 100 mm. This creates a wide 70-170 mm usable stroke window, giving you immense flexibility to dial in exact end positions during commissioning without swapping hardware. It delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa, fitting perfectly into medium-duty automation setups.
This SKU ships configured with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a piston magnet (-S) for seamless position feedback. It is fully compatible with AirTAC CMSE reed and DMSE solid-state sensors, which seat neatly into the dual-sided sensor grooves on the extruded aluminum barrel. The G3/8 port and M16x1.5 rod thread provide robust pneumatic flow and mounting strength for dynamic cycling at 30-800 mm/s.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-100S Is Used
Variable End-Stop Tuning
Dial in the exact 70-170 mm travel distance during machine commissioning to accommodate varying material lengths without adding external mechanical stops.
Product Changeover
Quickly reconfigure the retract position on a packaging line when switching between different carton or product sizes, minimizing downtime.
Sensor Calibration
Leverage the built-in magnet and CMSE/DMSE sensor grooves to verify and fine-tune the end-of-stroke position precisely against the mechanical adjuster.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-100S the Right Cylinder?
Choose this 63 mm bore when your application requires around 1559 N of push force at 0.5 MPa. If you need less force, stepping down to a 50 mm bore yields 982 N; if your load demands more, stepping up to an 80 mm bore provides 2513 N. The massive 100 mm adjustment range is perfect for machines running multiple product sizes, acting as a variable end-stop. Remember that the rear adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure. For true load-holding, consider SAIL or BSAI cylinders. As an ISO 15552 interchangeable cylinder, replacement requires matching the 63 mm bore, 170 mm stroke, PT tapered G3/8 ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounts, and the -S magnet.
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 SAIJ63AX170-100S FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. If operating at 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw lets you shorten the 170 mm nominal stroke by up to 100 mm, creating a usable travel window of 70 to 170 mm. The adjuster acts as a mechanical stop to set the exact end position and does not lock the load without live air.
