About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-20S
The AirTAC SAIJ200X475-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers massive thrust, pushing with 28274N of force at 0.9 MPa, making it suitable for heavy-duty press operations. The built-in -S magnet enables position sensing via CMSE reed or DMSE electronic switches fitted into the dual-side barrel grooves.
This specific variant provides a 455-475 mm usable travel window, allowing technicians to dial back the nominal 475 mm stroke by up to 20 mm. It features an SUS420J2 stainless steel rod and a PT tapered port thread. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not lock the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-20S Is Used
Press Tuning
Dial in the exact 455-475 mm end-stop during heavy press commissioning to accommodate material thickness variations without external spacers.
Product Changeover
Quickly adjust the stroke window on automated assembly lines when switching between product sizes, saving setup time and avoiding cylinder swaps.
Heavy Material Handling
Utilize the 28274N push force at 0.9 MPa to move heavy pallets or components, relying on the SUS420J2 rod for durability in harsh environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-20S the Right Cylinder?
Select this 200 mm bore cylinder when an application requires up to 3204 kgf of maximum force at 1.0 MPa alongside precise end-position tuning. If you need less force, stepping down to a 160 mm bore yields 18095N of push force at 0.9 MPa. Choose the adjustable SAIJ format over a fixed SAI when a machine requires variable end-stops for product changeovers without swapping hardware. For load-holding without continuous air pressure, select a BSAI clamp-lock or SAIL pneumatic lock cylinder instead, as the SAIJ adjuster is only a travel stop.
Because the 475 mm stroke is substantial, the 40 mm diameter rod and M36x2 thread provide rigidity, but an external guide is still recommended to manage side loads. This SAIJ model uses PT port threads and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Operating speed is 30-500 mm/s.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ200AX475-20S FAQ
The nominal stroke is 475 mm, but the rear adjuster allows you to shorten the effective travel by up to 20 mm, creating a usable stroke window of 455 to 475 mm for fine-tuning end positions.
Because this model includes the -S magnet, it works directly with AirTAC CMSE reed switches and DMSE electronic solid-state sensors, which mount into the sensor grooves on both sides of the aluminum profile barrel.
