About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX20-20
The AirTAC SAIJ200X20-20 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 15708N of thrust at 0.5 MPa. A rear-mounted stroke adjuster allows you to fine-tune the nominal 20mm travel down to a 0mm fully retracted stop, providing a 0-20mm usable window for precise machine setup. This built-in adjustability eliminates the need to swap cylinders or bolt on external stops during product changeovers.
Equipped with a durable SUS420J2 stainless steel rod (material code A) and PT tapered port threads, this 200mm bore unit is built for demanding environments. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Unlike a tie-rod design, this profile cylinder integrates adjustable air cushions at both ends to decelerate the massive 3204kgf peak load smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX20-20 Is Used
Heavy Press Tuning
Dial in the exact 0-20mm travel window during machine commissioning to set precise pressing forces on heavy assemblies without changing hardware.
Product Changeover
Quickly adjust the rear stopper on the assembly line when switching between product variants that require slightly different short-stroke end positions.
High-Force Clamping
Leverage the 15708N thrust at 0.5 MPa for heavy-duty clamping tasks, using the rear screw to fine-tune the clamping depth precisely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX20-20 the Right Cylinder?
Selecting the SAIJ200X20-20 is ideal when your application requires extreme force combined with exact end-position tuning at commissioning. If you need slightly less thrust, stepping down to a 160mm bore yields 10053N at 0.5 MPa, but this 200mm model provides the maximum 15708N push force for high-inertia loads. The rear adjuster acts strictly as a travel stop to set the 0-20mm window, not a lock; it cannot hold a load without live air pressure. For fail-safe load holding without continuous air, consider the SAIL pneumatic lock series or an external pilot-operated check valve. This cylinder uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets.

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 SAIJ200AX20-20 FAQ
It features a rear adjusting screw that lets you shorten the 20mm nominal stroke by up to 20mm, creating a 0-20mm usable travel window. This allows you to fine-tune the retract end position at commissioning without adding external stops.
At a standard 0.5 MPa operating pressure, the SAIJ200X20-20 delivers 15708N of push force and 15080N of pull force. It can reach a maximum thrust of 28274N at 0.9 MPa.
