About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-30
The AirTAC SAIJ200X165-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 135 to 165 mm. Equipped with a SUS420J2 stainless steel rod (code A) and PT tapered port threads, it delivers massive thrust up to 15708 N at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible positioning of CMSE or DMSE switches.
This adjustable variant allows you to fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-30 Is Used
Heavy Press Tuning
Dial in the exact 135-165 mm end position during machine commissioning to ensure precise pressing force without mechanical shims.
Product Changeover
Quickly adjust the retract stop to accommodate different workpiece sizes on the same production line without changing cylinders.
Assembly Station Setup
Fine-tune the end-stop on heavy assembly fixtures to adapt for part tolerances, ensuring consistent clamping every cycle.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-30 the Right Cylinder?
Choose this 200 mm bore when the 160 mm class (offering 10053 N push at 0.5 MPa) is insufficient for your heavy-duty application. An adjustable stroke is ideal for product-size changeovers where the exact end-stop needs slight tuning. For load-holding without live pressure, select the SAIL or BSAI series instead. To match an ISO 15552 replacement, verify the 200 mm bore, 165 mm stroke, 30 mm adjust, PT ports, and no magnet.
Because the stroke is under 300 mm, side-load risks are lower, but the heavy 40 mm rod diameter and M36x2 thread still require proper guiding for long unsupported 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 SAIJ200AX165-30 FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach up to 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 165 mm stroke by up to 30 mm, creating a usable travel window of 135 to 165 mm. It acts as a mechanical stop and does not lock the load without air pressure.
