About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX900-75
The AirTAC SAIJ200X900-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a massive 15708N push force at 0.5MPa and utilizes a SUS304 stainless steel rod to withstand corrosive environments. By turning the rear stopper screw, you can fine-tune the effective travel down from the 900mm nominal stroke, creating an 825-900mm usable window without physically swapping the actuator.
Equipped with a PT tapered G3/4 port and 50mm air cushions at both ends, this heavy-duty unit safely decelerates substantial loads. The extruded aluminum barrel includes dual sensor grooves, though this specific configuration ships without a magnet. Remember that the rear adjuster acts only as a travel stop; it cannot hold a load without continuous live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX900-75 Is Used
Variable End-Stop Positioning
Dial in the exact 825-900mm travel distance during machine setup to adapt the conveyor stroke length for different carton sizes on the fly.
Product Changeover Tuning
Use the 75mm rear adjustment range to quickly reposition the end-of-stroke stop when switching the production line to a new pallet format.
Heavy-Duty Press Buffering
Leverage the 50mm variable air cushions alongside the mechanical stopper to safely decelerate the 15708N push force at the end of the 900mm stroke.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX900-75 the Right Cylinder?
When sizing this 200mm bore actuator, dropping down to a 160mm bore reduces the 0.5MPa pull force to 9425N, while stepping up is impossible within the standard range. You select the SAIJ200X900-75 over a fixed SAI when a machine requires commissioning flexibility or variable end-stops to accommodate multiple product sizes on a single line. To replace this unit, match the 200mm bore, 900mm stroke, 75mm adjustment, PT port, and SUS304 rod material. Because the 900mm stroke is long and unsupported, adding an external guide rail is strongly recommended to prevent excessive side-loading on the rod.
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 SAIJ200BX900-75 FAQ
The rear adjuster screw physically limits the piston's retract travel, allowing you to shorten the 900mm nominal stroke by up to 75mm, resulting in an 825-900mm usable travel window.
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force, scaling up to 21991N push at 0.7MPa.
