About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-75
The AirTAC SAIJ200X900-75 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 15708N of push force at 0.5 MPa. It features an external rear stroke adjuster that allows you to fine-tune the effective travel, creating a usable window of 825 to 900 mm without changing the cylinder body.
This unit utilizes an SUS420J2 stainless steel rod for enhanced durability against moisture and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches if needed.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-75 Is Used
Heavy Press Tuning
Dial in the exact 825-900mm end position during setup to accommodate varying workpiece heights without swapping tooling.
Product Changeover
Quickly adjust the stroke length by up to 75mm on a packaging line to handle different pallet or product sizes.
Large Assembly Stops
Use the rear stopper to set precise retraction limits for heavy 200mm bore automation equipment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-75 the Right Cylinder?
Choose this 200mm bore when the 160mm class (10053N push at 0.5 MPa) lacks the necessary thrust. The 75mm adjustment range is ideal for product-size changeovers on a line, letting you dial in the exact end-stop during commissioning rather than adding external stops. For this 900mm stroke, an external guide is recommended to handle side loading and protect the 40mm rod.
To match ISO 15552 interchangeability, specify the 200mm bore, 900mm stroke, PT ports, and your required mounting from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, TCM2. Note that the rear adjuster is a travel stop, not a lock; for load-holding without live air, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ200AX900-75 FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 900mm nominal stroke by up to 75mm, resulting in an effective travel range of 825-900mm. It only sets the end position and does not hold the load without live air.
