About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-20S
The AirTAC SAIJ200X165-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 145-165 mm, allowing you to dial back the nominal 165 mm stroke by up to 20 mm during commissioning. Delivering massive thrust, it pushes with 15708 N and pulls with 15080 N at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This specific SKU is equipped with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threads with a G3/4 connection. The integrated magnet (-S) supports position feedback via AirTAC CMSE reed and DMSE electronic sensors. It features variable air cushions at both ends to manage heavy kinetic energy.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-20S Is Used
Heavy Press Tuning
Fine-tune the 145-165 mm travel window during machine setup to set precise pressing depths on heavy-duty assembly lines without mechanical rework.
Product Changeover
Quickly adjust the end-stop for varying large product sizes on a conveyor, using the rear screw to adapt the stroke on the fly.
Large Mold Handling
Position heavy molds accurately using the 15708 N push force, relying on the SUS420J2 stainless rod for durability in industrial environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-20S the Right Cylinder?
Choose this 200 mm bore when maximum force is required, stepping up from a 160 mm bore that pushes 10053 N at 0.5 MPa. The adjustable stroke is ideal for product changeovers, letting you fine-tune the end position without swapping the cylinder or adding external stops. The rear adjuster and air cushions only set the travel end and decelerate the load; they do not hold the load without live air. For true load-holding, use an external rod lock or explore the SAIL or BSAI series.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. The robust 40 mm rod and M36x2 thread handle high side loads, but because the stroke is 165 mm, always ensure proper external guiding for heavy loads.
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 SAIJ200 Adjustable Cylinder SAIJ200AX165-20S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. It can reach a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 165 mm down to 145 mm. This creates a 145-165 mm adjustable window, allowing precise end-position tuning at commissioning without replacing the cylinder.
