About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-75S
The AirTAC SAIJ63X100-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a highly versatile usable travel window of 25-100 mm. Delivering 1559 N of pull force at 0.5 MPa, it handles substantial workloads while allowing precise end-position tuning during commissioning without swapping out the cylinder.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions, and fluid control is managed through PT tapered G3/8 ports.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-75S Is Used
Variable Product Changeover
Ideal for packaging lines running mixed product sizes, using the 75 mm adjustment window to rapidly reconfigure the end-stop position for different carton depths without changing hardware.
Commissioning End-Tuning
Allows maintenance teams to dial in the exact 25-100 mm travel distance during machine setup, fine-tuning the stroke to perfect the seating force of pressing operations.
Sensor-Driven Positioning
The integrated magnet works with DMSE electronic sensors to confirm end-of-stroke arrival across the adjusted travel range, ensuring reliable operation in automated assembly cells.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX100-75S the Right Cylinder?
Choose this 63 mm bore when you need more force than a 50 mm cylinder (which provides 825 N pull at 0.5 MPa) but want to avoid the bulk of an 80 mm unit. The generous 75 mm adjustment range is ideal for machines requiring extreme product-size changeover flexibility, acting as an external stop built into the rear cap. To match this cylinder exactly when replacing an ISO 15552 unit, confirm the 100 mm nominal stroke, 75 mm adjuster, PT G3/8 port, and the -S magnet.
Because the rear adjuster acts only as a travel stop and the air cushions handle deceleration, this SAIJ model cannot hold a load without live air pressure. For dead-load holding requirements, consider an AirTAC SAIL pneumatic lock or an external pilot-operated check valve. 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 SAIJ63AX100-75S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its 100 mm nominal length down to as little as 25 mm. It sets the travel end-point but does not lock the load without continuous air pressure.
