About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-10
The AirTAC SAIJ200X190-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 28274N at 0.9 MPa. It features an extruded aluminum barrel with sensor grooves on both sides and uses a robust 40mm piston rod with an M36x2 thread. Because this configuration uses code A, the rod is manufactured from SUS420J2 stainless steel for enhanced durability against harsh environments.
This model provides a 180-190mm adjustable travel window, allowing you to trim the nominal 190mm stroke by up to 10mm during commissioning. The PT tapered port threads ensure a tight pneumatic seal at the G3/8 connection. It operates at speeds of 30-500mm/s and relies on 50mm air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-10 Is Used
Heavy Press Tuning
Dial in the exact 180-190mm end position during machine commissioning to accommodate thick material variations without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper by up to 10mm on the fly when switching between slightly different product sizes on the line.
Large Assembly Jigs
Leverage the 28274N push force at 0.9 MPa to seat heavy components, using the fine adjustment to prevent over-travel damage.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX190-10 the Right Cylinder?
Select this 200mm bore cylinder when an application demands extreme force, such as 15708N push at a conservative 0.5 MPa, but still requires precise end-position tuning without external stops. If your setup only needs 10053N of push force at 0.5 MPa, stepping down to the 160mm bore saves space and air consumption. Choose the SAIJ adjustable version over a fixed SAI when you need a variable end-stop for product changeovers.
Since the 190mm stroke is below the 300mm threshold, side-load risks are moderate, but the heavy 40mm rod still requires proper external guiding for long-term seal integrity. Remember that the rear adjuster is a travel stop, not a locking device; this cylinder cannot hold a load without live air, so consider a SAIL or BSAI cylinder if true load-holding is required. For drop-in ISO 15552 replacement, match the 200mm bore, 190mm stroke, PT port, and mounting choices (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ Required force at your working pressure
- ✓ 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 SAIJ200AX190-10 FAQ
At 0.5 MPa it provides 15708N of push force and 15080N of pull force. At 0.9 MPa, the push force increases to 28274N.
The rear adjuster acts as an external stopper, letting you shorten the effective travel from 190mm down to 180mm. It sets the end position but does not lock the load without continuous air pressure.
