About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-30S
The AirTAC SAIJ200X165-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa and pulling 15080N at 1.0 MPa, making it ideal for heavy-duty operations. The integrated -S magnet enables position detection via AirTAC CMSE reed and DMSE electronic solid-state sensors housed in the dual-side barrel grooves.
This specific SKU features a 30mm adjustment range, allowing you to fine-tune the effective travel window from 135 to 165mm during commissioning without adding external stops. It features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and utilizes PT tapered port threads (G3/4) for a high-integrity pneumatic seal.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-30S Is Used
Heavy Machinery Setup
Dial in the 135-165mm stroke window during equipment commissioning to perfectly time heavy press strokes without machining custom spacers.
Product Size Changeover
Rapidly adjust the retract end-position by up to 30mm on packaging lines when switching between different large-format product dimensions.
Variable End-Stop Positioning
Use the rear stopper screw to fine-tune the final resting position of heavy 28274N loads on automated assembly lines.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-30S the Right Cylinder?
Choose this 200mm bore actuator when your application requires the highest standard force class, as stepping down to a 160mm bore reduces your 0.9 MPa push force to 18095N. The adjustable stroke is highly beneficial for machine setups requiring variable end-stops or product-size changeovers, functioning as a rear travel stop rather than a fixed-stroke SAI cylinder. Note that the rear adjuster and air cushions only decelerate the end-of-travel; they do not hold the load without live air. For static load-holding, consider an external rod lock or the AirTAC SAIL series.
Because the 165mm stroke is well below the 1500mm maximum standard stroke, it ships as a standard catalog item. However, with a 40mm rod diameter and M36x2 thread, long unsupported strokes still require an external guide to prevent side-loading damage. This SAIJ model uses the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets.
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 SAIJ200AX165-30S FAQ
At 0.9 MPa, this 200mm bore cylinder provides a push force of 28274N and a pull force of 15080N. At the maximum operating pressure of 1.0 MPa, it achieves a maximum push force of 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 165mm stroke by up to 30mm. This creates a usable travel window between 135mm and 165mm, allowing precise end-position tuning without replacing the cylinder.
