About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-75
The AirTAC SAIJ200X375-75 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion control. A rear adjusting screw allows you to dial back the effective travel by up to 75mm, creating a highly versatile 300-375mm usable stroke window. This on-cylinder fine-tuning eliminates the need to swap out hardware or bolt on external stops during machine commissioning or product changeovers.
Equipped with a sizable 40mm carbon steel rod and M36x2 thread, this unit handles substantial side loads, though a 375mm stroke still necessitates an external guide to prevent rod binding. The extruded aluminum barrel incorporates sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic switches. It operates efficiently between 30-500mm/s and utilizes PT tapered G3/4 ports, while the rear stopper strictly manages end-position deceleration rather than locking the load.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-75 Is Used
Heavy Press Positioning
Dial in the exact 300-375mm end position for large stamping or pressing operations without physically remounting the cylinder.
Product Changeover Stops
Adjust the travel limit on the fly when switching between different sized products on a heavy-duty transfer line.
Large Assembly Tuning
Fine-tune the retraction point during machine setup to perfectly align heavy components prior to final clamping.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-75 the Right Cylinder?
Select this 200mm bore model when an application demands extreme thrust up to 15708N at 0.5MPa, stepping up significantly from the 160mm bore which provides 10053N. The 75mm rear adjuster is ideal for variable end-stop positioning, letting operators trim the travel window down to 300mm without replacing the cylinder.
Because the stroke is 375mm, supporting the load with an external guide is critical to prevent excessive wear on the rod seal. Remember that the SAIJ rear adjuster functions only as a travel stop and cannot hold a load without live air pressure; for true fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series. This cylinder is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200X375-75 FAQ
The rear adjusting screw acts as an external stopper that shortens the retract stroke by up to 75mm. This gives the 375mm stroke cylinder a usable travel window of 300-375mm, allowing precise end-position tuning at commissioning without swapping out the cylinder.
At the maximum 1.0MPa pressure, the push force reaches 3204kgf.
