About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-10
The AirTAC SAIJ200X175-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 165-175 mm usable travel window, letting you trim up to 10 mm off the nominal 175 mm stroke during machine setup. In the 200 mm bore class, it generates 15708 N of push thrust and 15080 N of pull thrust at 0.5 MPa, making it suited to moving heavy loads.
This variant features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is supplied without a magnet. The rear adjustment mechanism acts purely as a travel stop for end-position tuning, not as a lock, so live air pressure is required to hold the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-10 Is Used
Heavy Press Tunning
Dial in the exact 165-175 mm retract position on a heavy press without adding external mechanical stops or changing the cylinder.
Product Changeover
Quickly adjust the end-stop by up to 10 mm on a production line to accommodate a slightly shorter new product variant.
Large Assembly Alignment
Fine-tune the end position of heavy components during automated assembly, relying on the 15708 N push force to move the load.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-10 the Right Cylinder?
Select this 200 mm bore cylinder when an application demands very high thrust—up to 15708 N at just 0.5 MPa—combined with a 165-175 mm adjustable stroke window. The 10 mm rear stopper is ideal for fine-tuning the retract end position during commissioning or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. Because the standard stroke is 175 mm, an external guide is recommended to manage side loads on the 40 mm rod.
When specifying a replacement, verify the 200 mm bore, 175 mm nominal stroke, 10 mm adjustment range, PT G3/4 port threads, and SUS420J2 rod material. Note that this plain SAIJ model does not hold position without live air; for fail-safe load holding, consider the SAIL or BSAI series. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the 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 SAIJ200AX175-10 FAQ
At 0.5 MPa operating pressure, 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 its maximum 1.0 MPa pressure rating.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 175 mm down to 165 mm. It is used for fine-tuning the end position at commissioning and does not lock or hold the load without live air pressure.
