About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-100S
The AirTAC SAIJ63X160-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 1559N pull force at 0.5MPa and uses a 20mm diameter SUS420J2 stainless steel rod. The built-in adjuster allows you to trim the nominal 160mm stroke back by up to 100mm, creating a highly flexible 60-160mm usable travel window for precise commissioning.
Because the barrel is an extruded aluminum profile rather than a tie-rod design, it carries sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear mechanism acts purely as a physical stop to set the end position; it does not lock the load. For position holding without live air pressure, an external rod lock or a SAIL pneumatic-lock cylinder is required.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-100S Is Used
Variable End-Stop Tuning
Dial the travel down from 160mm to exactly 60mm during commissioning to match varying product widths without changing the cylinder.
Machine Changeover
Rapidly adjust the retract end-position for new product runs using the rear stopper screw, minimizing downtime between batches.
Position Sensing Setup
Utilize the -S magnet and dual sensor grooves to mount DMSE electronic switches precisely at the newly tuned end-position.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-100S the Right Cylinder?
Choose this 63mm bore when a 50mm bore (825N pull at 0.5MPa) lacks the power to retract your tooling, but an 80mm bore (2268N pull) would be physically oversized. The 100mm adjustment range is ideal for machines that run multiple product sizes, allowing operators to dial in the exact end-stop without swapping cylinders or adding external stops. The PT tapered G3/8 port matches the bore size, and the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omits FB, CA, CB, and CR. Since the 160mm stroke is below the 300mm side-load threshold, standard mounting is sufficient without an external guide.
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 SAIJ63AX160-100S FAQ
At 0.5MPa, it provides 1559N of retract (pull) force and 2182N of extend (push) force. The maximum thrust is 318 kgf at 1.0MPa.
The rear adjuster acts as a travel stop, allowing you to shorten the effective stroke from 160mm down to 60mm. This creates a 60-160mm usable window for fine-tuning end positions without replacing the cylinder.
