About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-40S
The AirTAC SAIJ200X600-40-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. Featuring a 200mm bore and a 600mm stroke, it integrates a rear adjusting screw that allows you to shorten the effective travel by up to 40mm. This creates a usable 560-600mm travel window, enabling fine-tuning at commissioning without swapping the cylinder or adding external stops. At 0.5 MPa, it delivers 15708N of push force and 15080N of pull force.
This variant features a SUS420J2 stainless steel rod for enhanced durability against moisture and a PT tapered port thread for a robust pneumatic seal. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors. It operates at 30-500 mm/s and utilizes variable air cushions at both ends to manage deceleration. Remember that the rear adjuster and cushions act as travel stops, not as locks; use a SAIL or BSAI cylinder if you need to hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-40S Is Used
Heavy Press Tuning
Dial in the exact 560-600mm travel end-stop during press commissioning to accommodate varying material thicknesses without machining new spacers.
Product Changeover
Quickly adjust the retract position on automated assembly lines when switching between different product sizes, minimizing downtime.
Large Mold Positioning
Fine-tune the end-of-stroke contact point for heavy mold alignment, relying on the rigid 40mm rod and external guides to handle the load.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-40S the Right Cylinder?
Selecting this 200mm bore model provides massive thrust, pushing 21991N at 0.7 MPa, making it ideal for large presses and heavy material handling. If your application requires less force, stepping down to a 160mm bore yields 10053N at 0.5 MPa, which might better suit mid-range actuation without oversized valving. The adjustable stroke is specifically chosen for machine setups where product changeovers require variable end-stops, offering flexibility that a fixed-stroke SAI cylinder cannot provide.
When replacing an ISO 15552 cylinder, match the 200mm bore, 600mm stroke, PT port, and the 40mm adjustment range. Because the 600mm stroke is substantial and the rod is 40mm in diameter, long unsupported strokes still require an external guide to prevent side-loading damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR brackets to focus on rigid linear and foot-mount configurations.

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 SAIJ200AX600-40S FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 21991N.
The rear adjuster screw allows you to trim the 600mm nominal stroke back by up to 40mm, creating a usable travel window of 560 to 600mm. This stopper sets the retract end position but does not lock the load without live air pressure.
