About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX85-10
The AirTAC SAIJ200X85-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 75-85 mm. Delivering 15708 N of push force at 0.5 MPa, this 200 mm bore actuator handles heavy-duty positioning with precision. The extruded aluminum barrel features sensor grooves on both sides, though this specific configuration omits the magnet option.
This model features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The rear adjusting screw allows you to trim the effective stroke by up to 10 mm during commissioning without adding external stops. The standard variable air cushion at both ends decelerates the massive moving load, but remember the adjuster acts only as a travel stop, not a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX85-10 Is Used
Heavy Press Tuning
Fine-tune the 75-85 mm travel window during heavy press commissioning to achieve exact bottom-dead-center positioning without external stopper blocks.
Product Size Changeover
Quickly adapt large-scale automated machinery to new product dimensions by dialing the rear adjuster up to 10 mm instead of changing the entire cylinder.
High-Force Positioning
Leverage the 15708 N push force to move heavy pallets or industrial components, relying on the SUS304 rod for durability in harsh environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX85-10 the Right Cylinder?
Choose this 200 mm bore cylinder when an application demands up to 15708 N of thrust at 0.5 MPa and requires exact end-position tuning; if you need less force, stepping down to the 160 mm bore yields 10053 N of push force. The adjustable stroke is ideal for product changeovers on heavy machinery, allowing you to dial in the 10 mm trim window rather than swapping out a fixed-stroke SAI cylinder. For load-holding without live air pressure, integrate an external rod lock or look to the SAIL or BSAI series, as the SAIJ adjuster cannot hold a load.
When replacing an ISO 15552 actuator, match the 200 mm bore, 85 mm nominal stroke, 10 mm adjustment range, PT port threads, and SUS304 rod material. Because this is a large-bore actuator, ensure your mounting choice from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) adequately supports the weight, and always use an external guide to manage side loads.

- ✓ 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 SAIJ200BX85-10 FAQ
At a standard operating pressure of 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the 85 mm nominal stroke by up to 10 mm, creating a 75-85 mm usable travel window. It sets the end position but does not lock or hold the load without continuous air pressure.
