About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-75
The AirTAC SAIJ200X475-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, to handle heavy industrial loads. The built-in rear stopper allows you to shorten the effective travel, providing a precise 400-475 mm usable window for dialing in end positions during commissioning.
This model uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features a robust M36x2 rod thread paired with G3/4 PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. It operates at 30-500 mm/s and includes variable air cushions at both ends to decelerate high-mass payloads smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-75 Is Used
Heavy Press Tuning
Fine-tune the 400-475 mm stroke window during commissioning to set exact pressing depths on large metal components without adding external mechanical stops.
Product Line Changeover
Quickly adjust the retract end-position by up to 75 mm when switching machinery to accommodate different product sizes on the same assembly line.
Guided Heavy Lifting
Leverage the 28274N push force for lifting massive jigs, relying on an external guide to manage side loads on the long 475 mm stroke.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-75 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force—up to 21991N push at 0.7 MPa—and a variable end-stop. If your setup needs less thrust, stepping down to a 160 mm bore still yields 14074N at 0.7 MPa. The adjustable stroke is ideal for product changeovers where the exact end position varies, saving you from swapping out a fixed-stroke SAI cylinder or bolting on external stops.
Because this unit features a 475 mm stroke, the long unsupported piston rod is susceptible to side loads; always use an external guide to prevent binding. Remember that the rear adjuster and air cushions act only as travel stops and deceleration—they do not hold the load without live air. For fail-safe load holding, consider an external rod lock or the AirTAC SAIL or BSAI clamp-lock series. For an ISO 15552 replacement, match the 200 mm bore, 475 mm stroke, 75 mm adjustment, PT G3/4 ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2—omitting FB, CA, CB, CR).

- ✓ 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 SAIJ200AX475-75 FAQ
At 0.9 MPa, this 200 mm bore cylinder generates 28274N of push force and 3204 kgf at 1.0 MPa. It is designed for heavy-duty industrial applications requiring massive thrust.
The rear adjuster acts as a mechanical stop that lets you trim the nominal 475 mm stroke back by up to 75 mm, yielding a 400-475 mm usable travel window. It sets the end position but does not lock or hold the load without live air pressure.
