About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX210-100
The AirTAC SAIJ200X210-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 110-210 mm usable travel window by allowing you to trim the 210 mm nominal stroke back by up to 100 mm during commissioning. This massive bore generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it ideal for heavy-duty positioning.
This configuration uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel features sensor grooves on both sides for CMSE reed or DMSE electronic switches, though no magnet is specified for this specific SKU. The rear adjuster acts purely as a travel stop to fine-tune the end position, meaning it will not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX210-100 Is Used
Heavy Pressing Operations
Delivers 15708 N of thrust at 0.5 MPa for heavy assembly or pressing tasks, with the 100 mm rear adjuster allowing precise tuning of the final pressing depth.
Product Changeover Setup
Quickly adapt the 210 mm stroke down to a 110 mm effective travel window during line changeovers without physically replacing the cylinder or re-engineering external stopper blocks.
Large Material Handling
Moves substantial loads in automated facilities using the robust 40 mm SUS304 stainless steel rod, while the PT tapered ports ensure secure high-flow pneumatic connections.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX210-100 the Right Cylinder?
Select this 200 mm bore cylinder when your application requires extreme thrust up to 15708 N at 0.5 MPa, stepping up from a 160 mm bore that provides 10053 N. The 100 mm adjustment range is highly valuable for product changeovers, letting you dial back the 210 mm stroke to a precise shorter dimension without adding external stops or swapping the cylinder. For load-holding without continuous air pressure, this standard adjuster cannot lock the load; you would need to explore the SAIL air-released lock or BSAI clamp-lock series instead.
Because this is a large 200 mm bore cylinder driving a 210 mm stroke, the M36x2 rod thread and 40 mm rod diameter provide high rigidity, but any long unsupported stroke still requires an external guide to prevent side-loading damage. It supports the reduced SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Operating speed is rated for 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 SAIJ200BX210-100 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. The maximum operating pressure is 1.0 MPa, and the standard speed range is 30-500 mm/s.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 210 mm nominal stroke down to as little as 110 mm. This allows precise end-position tuning during commissioning, but it is only a stop and does not lock or hold the load without live air pressure.
