About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-50
The AirTAC SAIJ200X145-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers immense thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa. By integrating a 50 mm adjustment mechanism, this unit creates a usable travel window of 95 to 145 mm, allowing technicians to dial in the exact retract distance without swapping components.
This heavy-duty actuator features a SUS420J2 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads with a G3/4 connection. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning position sensing via CMSE or DMSE switches requires adding the -S option.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-50 Is Used
Heavy Press Tuning
Fine-tune the retract distance of high-tonnage pressing operations within the 95-145 mm window to accommodate varying material thicknesses without external stopper blocks.
Product Changeover
Rapidly adjust the end position on a machining line during product family transitions, using the 50 mm trim range to set new operational limits at commissioning.
Assembly Actuation
Drive large-scale assembly tooling with 15708 N of thrust at 0.5 MPa, relying on the SUS420J2 stainless rod to withstand harsh industrial environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-50 the Right Cylinder?
Selecting this 200 mm bore actuator is ideal when an application demands up to 3204 kgf of maximum force at 1.0 MPa alongside precise end-stop tuning. If the 95-145 mm adjustable retract distance is excessive, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa. Because the 145 mm stroke is below the 300 mm threshold, external side-load guides are less critical, though the robust 40 mm rod and M36x2 thread naturally handle substantial mechanical stress.
The rear screw functions purely as a travel stop and works with the variable air cushions to decelerate the payload, but it cannot hold the load without live air pressure. For secure load-holding in the event of pressure loss, consider the SAIL pneumatic lock or BSAI clamp-lock series. This profile cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200AX145-50 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that shortens the effective stroke. For this 145 mm nominal stroke cylinder, the 50 mm adjustment creates a usable travel window of 95 to 145 mm, enabling precise end-position tuning without replacing the cylinder.
