About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-100
The AirTAC SAIJ200X375-100 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster. It provides a nominal 375 mm stroke that can be fine-tuned down by up to 100 mm, yielding a usable travel window of 275-375 mm. This allows precise end-position calibration during commissioning without swapping out the physical cylinder. As an extruded aluminum profile barrel, it integrates cleanly into standard setups.
Built for heavy loads, this 200 mm bore generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling up to a maximum of 3204 kgf at 1.0 MPa. It features a durable SUS304 stainless steel rod, PT tapered ports, and variable air cushions at both ends. Note that the rear adjuster acts strictly as a travel stop to decelerate the piston, not as a locking device to hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-100 Is Used
Heavy Press Tuning
Dial in the exact 275-375 mm end-stop during heavy press commissioning to accommodate different material thicknesses without adding external stops.
Product Changeover
Adjust the rear stopper by up to 100 mm on the fly to handle varying package sizes on a high-thrust transfer line.
Large Assembly Jigs
Leverage the 15708 N push force at 0.5 MPa to move heavy structural components, fine-tuning the final seating position during machine setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX375-100 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires massive thrust, such as 15708 N push force at 0.5 MPa, and demands on-the-fly stroke trimming. If you need a shorter fixed stroke without adjustment, the standard SAI series is simpler, but the SAIJ200X375-100 shines in product-size changeovers where the end-stop varies by up to 100 mm. To match this SKU exactly for an ISO 15552 replacement, specify: 200 mm bore, 375 mm stroke, 100 mm adjustment, PT ports, SUS304 rod, and no magnet.
Because the stroke is 375 mm, the M36x2 piston rod must handle significant leverage; ensure you use an external guide to prevent excessive side-loading on the seals. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. If your process requires true load-holding without continuous air pressure, integrate an external pilot-operated check valve or select the SAIL or BSAI locking cylinder series instead.

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 SAIJ200BX375-100 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf of thrust.
The rear adjuster screw lets you shorten the effective travel from the nominal 375 mm down to 275 mm. This creates a flexible 275-375 mm window for fine-tuning the end position at commissioning, though it functions only as a stop and does not lock the load without air pressure.
