About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX185-10S
The AirTAC SAIJ63X185-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 175-185 mm, letting you dial back the nominal 185 mm stroke by up to 10 mm during commissioning without adding external stops. In the 63 mm bore class, it delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa, giving you robust thrust for mid-range actuation.
This SKU ships with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides. It supports a speed range of 30-800 mm/s and uses a G3/8 port, while the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX185-10S Is Used
Machine Changeover
Dial in the exact 175-185 mm end position during product size changes without swapping out the entire actuator.
Variable End Stops
Use the 10 mm rear adjustment screw to fine-tune the retract stroke precisely to the sensor target.
Assembly Positioning
Provides 1559 N of thrust at 0.5 MPa for pressing or locating parts accurately on the production line.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX185-10S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires precise end-position tuning at changeover rather than a fixed stop. If your application needs less force, stepping down to a 50 mm bore yields 982 N of push force at 0.5 MPa; stepping up to an 80 mm bore provides 2513 N. Because the SAIJ63X185-10-S uses a 20 mm piston rod with an M16x1.5 thread, it handles moderate side loads well, though any long unsupported stroke still requires an external guide.
For an exact ISO 15552 replacement, match the 63 mm bore, 185 mm stroke, 10 mm adjustment range, PT tapered port threads, and the -S magnet option. The compatible mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that this cylinder does not hold loads pneumatically without live air; for fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ63AX185-10S FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 318 kgf of push force.
The rear adjuster acts as a mechanical stop that trims the effective travel back from the 185 mm nominal stroke down to as little as 175 mm. This allows fine-tuning of the end position at commissioning, but it is not a lock and will not hold the load without live air pressure.
