About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-100
The AirTAC SAIJ200X145-100 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708N and pulling 15080N at 0.5 MPa. The integrated rear stopper allows you to trim the effective travel, creating a 45-145mm usable window from the 145mm nominal stroke without swapping hardware.
This unit features a SUS420J2 stainless steel rod for enhanced durability and PT tapered port threads. It uses a G3/4 port and includes variable air cushions at both ends. The rear screw acts purely as a travel stop for product changeovers, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-100 Is Used
Heavy Press Tuning
Dial in the exact end-of-stroke position for high-force pressing applications during initial machine commissioning.
Product Changeovers
Adjust the 45-145mm travel window on the fly to accommodate different sized pallets or products on a packaging line.
Assembly Station Setup
Fine-tune the retract distance on heavy assembly lines without machining new hard stops or replacing the cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-100 the Right Cylinder?
Choose this 200mm bore when 160mm is insufficient, as the 160mm bore yields 10053N of push force at 0.5 MPa compared to the 15708N provided here. The 100mm adjustment range is ideal for machinery requiring frequent product-size changeovers, allowing precise end-position tuning at commissioning instead of adding external stops. For load-holding without continuous air pressure, select a SAIL or BSAI cylinder, as this adjuster is only a stop.
When replacing an ISO 15552 cylinder, match the 200mm bore, 145mm stroke, 100mm adjustment, G3/4 PT ports, and your required mounting style. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 145mm stroke is under 300mm, side-load concerns are minimal, but the 40mm rod and M36x2 thread handle high stresses well.
Quick checklist
- ✓ 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 SAIJ200AX145-100 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides a push force of 15708N and a pull force of 15080N. The maximum push force is 28274N at 0.9 MPa.
The rear adjuster screw lets you shorten the 145mm nominal stroke by up to 100mm, creating a usable travel window of 45 to 145mm. This allows precise end-position tuning without changing the cylinder.
