About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-10S
The AirTAC SAIJ63X190-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down to 180-190 mm without swapping the unit. Delivering 1559 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod for enhanced durability against moisture and light corrosion. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works seamlessly with CMSE reed and DMSE electronic switches for exact position feedback.
Because the rear screw acts purely as a mechanical stop to set the end position, it does not lock the load without live air pressure. For applications requiring true position holding, consider the SAIL or BSAI series. The 63 mm bore utilizes a G3/8 port and a 36 mm cushion length to absorb kinetic energy, while the M16x1.5 rod thread handles high side loads effectively.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-10S Is Used
End-Stop Calibration
Dial in the exact 180-190 mm travel distance during machine setup to accommodate varying material thicknesses without external stops.
Product Changeover
Quickly adjust the rear screw on the line when switching product sizes, minimizing downtime and avoiding cylinder disassembly.
Assembly Positioning
Leverage the 1559 N push force and fine-tuned travel to seat components accurately, using the integrated magnet for DMSE sensor feedback.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-10S the Right Cylinder?
Select this 63 mm bore adjustable cylinder when you need precise end-position tuning during commissioning or product changeovers, stepping down from an 80 mm bore (2268 N pull at 0.5 MPa) to save space, or up from a 50 mm bore (982 N push) when you need extra thrust. The 10 mm adjustment window is ideal for dialing in exact stops without adding external spacers. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. To match this ISO 15552 replacement exactly, specify the 190 mm stroke, 10 mm adjust, G3/8 PT port, SUS420J2 (A) rod material, and the -S magnet.

- ✓ 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 SAIJ63AX190-10S 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 reach up to 318 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster screw allows you to shorten the effective travel from the nominal 190 mm down to 180 mm. This provides a 180-190 mm usable window for fine-tuning the end position at commissioning, but it acts only as a stop and does not lock the load without continuous air pressure.
