About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX185-10S
The AirTAC SAIJ200X185-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial the effective travel down by 10 mm to a 175-185 mm window. In the 200 mm bore class, it delivers substantial thrust, pushing 28274 N at 0.9 MPa and pulling 15080 N at 0.5 MPa. This specific SKU is built with a SUS304 stainless steel rod (option B) and features PT tapered ports.
Because the adjustment mechanism acts purely as a mechanical stop at the retract end, it does not lock the load without live air pressure. For true load-holding, you would need a SAIL pneumatic lock, a BSAI clamp-lock, or an external pilot-operated check valve. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed and DMSE electronic switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX185-10S Is Used
Heavy Press Tuning
Dial in the exact 175-185 mm bottoming position on a large press to accommodate material thickness variations without swapping cylinders.
Product Changeover
Adjust the retract stopper quickly on automated assembly lines when switching to a new product size that requires a slightly shorter travel.
Automated Welding
Position large weldments accurately using the 28274 N push force at 0.9 MPa, fine-tuning the stroke to maintain precise electrode gaps.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX185-10S the Right Cylinder?
Choose this 200 mm bore if your application requires extreme force—such as the 21991 N generated at 0.7 MPa—and needs precise end-position tuning during commissioning without adding external stops. If you can operate with less push force, stepping down to a 160 mm bore yields 14074 N at 0.7 MPa, which might better suit medium-duty cycles.
When replacing an ISO 15552 cylinder, match the 200 mm bore, the 185 mm nominal stroke, the 10 mm adjustment range, the PT port thread, and the -S magnet requirement. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Since the 40 mm diameter rod and M36x2 thread handle heavy side loads, ensure your external guide supports the load for this long stroke.
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 SAIJ200BX185-10S FAQ
The rear adjuster screw lets you shorten the nominal 185 mm stroke by up to 10 mm, creating a 175-185 mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At 0.9 MPa operating pressure, the SAIJ200X185-10-S generates a push force of 28274 N and a pull force of 15080 N at 0.5 MPa. The maximum operating pressure is 1.0 MPa.
