About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-50
The AirTAC SAIJ200X650-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust with a 15708N push force at 0.5 MPa. It features a SUS304 stainless steel rod and PT tapered ports. By turning the rear stopper screw, you can trim the effective travel within a 600-650 mm window, providing exact end-position tuning without swapping out the entire unit.
This adjustable-stroke design is ideal for product changeovers on heavy machinery. The extruded aluminum barrel includes sensor grooves on both sides, and because this configuration omits the magnet, you would add an -S suffix to utilize CMSE reed or DMSE electronic switches. The rear adjuster acts strictly as a travel stop to set deceleration, not as a lock to hold the load without live air.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-50 Is Used
Heavy Press Tuning
Dial in the exact 600-650 mm retraction depth during machine commissioning to accommodate varying material thicknesses without adding external stopper blocks.
Product Changeover
Quickly adjust the end-of-stroke position on a packaging line when switching to a different pallet size, leveraging the 50 mm trim window for rapid setup.
Large Assembly Fixtures
Position heavy components precisely using the 21991N push force at 0.7 MPa, relying on the rear stopper to set the final resting place accurately.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-50 the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires up to 21991N of push force at 0.7 MPa and on-the-fly stroke trimming. If you need less force, stepping down to a 160 mm bore yields 14074N at 0.5 MPa. The 50 mm adjustment range is perfect for fine-tuning the retracted position at commissioning, whereas a fixed-stroke SAI requires external stops for any travel changes. For load-holding without continuous air pressure, you must integrate an external pilot-operated check valve or switch to a SAIL or BSAI variant, as the SAIJ adjuster is not a brake.
Because the 650 mm stroke is substantial, the 40 mm diameter SUS304 rod will still experience deflection under high side loads; always use an external guide rail to prevent binding. This model is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Operating speed for this bore size ranges from 30-500 mm/s.

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 SAIJ200BX650-50 FAQ
At a 0.5 MPa operating pressure, it provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster screw lets you shorten the 650 mm nominal stroke by up to 50 mm, creating a 600-650 mm usable travel window. It acts as a mechanical stop for end-position tuning and does not lock the load without air pressure.
