About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX90-30
The AirTAC SAIJ200X90-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust with 15708N push and 15080N pull at 0.5 MPa. Its defining feature is the external stopper screw, which creates a 60-90 mm usable travel window from the 90 mm nominal stroke. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
This unit features a SUS304 stainless steel rod (option B) for superior corrosion resistance and is configured with PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches, though this specific SKU is supplied without a magnet. Operating at 30-500 mm/s, it relies on its 50 mm air cushions to decelerate heavy loads, while the rear adjuster acts strictly as a travel stop rather than a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX90-30 Is Used
Heavy Press Tuning
Dial in the exact 60-90 mm travel window during heavy press commissioning to achieve perfect contact force without machining custom spacers.
Product Size Changeover
Quickly adjust the end-stop position on a production line when switching between heavy product variants, minimizing machine downtime.
Robotic End Effectors
Utilize the 15708N thrust and SUS304 rod for robust, corrosion-resistant actuation in demanding industrial automation environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX90-30 the Right Cylinder?
Choose this 200 mm bore cylinder when an application requires extreme force, as stepping down to a 160 mm bore reduces the 0.5 MPa push force to 10053N. An adjustable stroke is ideal for heavy machine setup or product-size changeovers, allowing operators to dial in the exact 60-90 mm travel distance on the fly instead of machining custom spacers. For any stroke at or above 300 mm, an external guide is required to manage side loads, though this 90 mm unit is compact enough to rely on its robust 40 mm rod and M36x2 thread for structural stability.
When specifying a replacement, ensure you match the 200 mm bore, 90 mm stroke, 30 mm adjustment range, PT port threads, and SUS304 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If the machine requires the load to be held without live air pressure, note that this cylinder's adjuster is only a stop; you must select an external rod lock or a related type like the SAIL or BSAI.

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 SAIJ200BX90-30 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708N and a pull force of 15080N. At the maximum 1.0 MPa pressure, it achieves a push force of 31416N.
The rear adjuster screw acts as a mechanical stop, allowing you to trim the effective stroke back by up to 30 mm from the 90 mm nominal length, creating a 60-90 mm usable travel window. It only sets the end position and does not lock or hold the load without continuous air pressure.
