About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-100
The AirTAC SAIJ200X200-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 100 to 200 mm usable travel window. In this configuration, the massive 200 mm bore generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it suited for heavy-duty pressing and lifting. The standard extruded aluminum barrel includes sensor grooves on both sides for straightforward position monitoring.
This variant utilizes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Pneumatic flow is managed via PT tapered G3/4 ports, while variable air cushions at both ends decelerate the heavy moving mass. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position without needing external physical stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-100 Is Used
Heavy Press Tuning
Dial in the exact 100 to 200 mm travel window during heavy-duty press setup, ensuring precise end-position control without physically swapping large actuators.
Assembly Line Changeover
Adapt a 200 mm stroke automated lifting station to new product sizes instantly by turning the rear stopper, minimizing mechanical downtime between runs.
Large Fixture Positioning
Set variable retract end-stops for heavy industrial fixtures, leveraging the 15708 N push force to move substantial payloads while fine-tuning the final resting position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-100 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires up to 3204 kgf of maximum thrust at 1.0 MPa, but demands on-the-fly travel adjustments during product changeovers. If 15708 N at 0.5 MPa is excessive for your load, stepping down to a 160 mm bore yields 10053 N of push force, halving air consumption while retaining a robust profile. The integrated 100 mm adjustment window allows operators to dial in the exact end position at commissioning without swapping out the cylinder.
Because this is a double-acting single-rod cylinder, the rear adjuster and air cushions function only as travel stops and deceleration devices; they cannot hold a load without continuous live air pressure. For fail-safe load holding, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve. To match this ISO 15552 dimensionally interchangeable cylinder, specify a 200 mm bore, 200 mm stroke, 100 mm adjustment range, PT G3/4 port, and the SUS420J2 (A) rod material. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting 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 SAIJ200AX200-100 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf. The operational speed range for this bore size is 30-500 mm/s.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 200 mm down to as little as 100 mm, creating a 100-200 mm usable travel window. It allows fine-tuning of the retract end position during commissioning without adding external stops, but it is not a lock and cannot hold the load without live air pressure.
