About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-20S
The AirTAC SAIJ200X105-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from 105 mm to a minimum of 85 mm. Delivering 15708 N of push force at 0.5 MPa and up to 28274 N at 0.9 MPa, it handles massive loads while maintaining a dimensionally interchangeable ISO 15552 mounting interface.
This SKU is equipped with a SUS420J2 stainless steel rod (code A) and a magnet for position sensing. It is designed for 30-500 mm/s operating speeds and includes variable air cushions at both ends to manage kinetic energy, while the PT tapered ports ensure a tight pneumatic seal.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-20S Is Used
Heavy Press Tuning
Dial in the exact 85-105 mm pressing distance during commissioning to accommodate different material thicknesses without swapping cylinders.
Assembly Line Changeover
Adjust the rear stopper quickly when switching product sizes on the line, reducing setup time and eliminating the need for external mechanical stops.
Large Fixture Positioning
Move and fine-tune heavy industrial fixtures with up to 28274 N of force at 0.9 MPa, relying on the robust SUS420J2 rod for durability.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-20S the Right Cylinder?
Choose this 200 mm bore when you need extreme thrust that smaller bores cannot provide, such as moving heavy assemblies. If you need less force, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa. The 20 mm adjustment range is ideal for dialing in exact end positions during machine commissioning or product changeover without adding external stops. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For load-holding, consider the SAIL or BSAI series. This cylinder uses the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is compatible with AirTAC CMSE reed and DMSE electronic sensors.

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 SAIJ200AX105-20S FAQ
The rear adjusting screw allows you to shorten the nominal 105 mm stroke by up to 20 mm, providing an effective travel window of 85-105 mm. This lets you set precise end positions at commissioning without changing the cylinder.
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At 0.9 MPa, the push force increases to 28274 N.
