About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX170-40S
The AirTAC SAIJ200X170-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, generating up to 28274N of push force at 0.9 MPa, making it suitable for heavy-duty operations. The integrated -S magnet enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed within the dual-side sensor grooves.
This specific SKU features a 170 mm nominal stroke that can be dialed back by up to 40 mm, creating a usable travel window of 130-170 mm. The adjustment is achieved via an external stopper screw at the rear, allowing you to fine-tune the retract end position during commissioning without swapping the cylinder or adding external stops. It utilizes a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread for a robust pneumatic connection.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX170-40S Is Used
Heavy Press Tuning
Dial in the exact 130-170 mm retract position during heavy press commissioning to accommodate varying material thicknesses without mechanical rebuilds.
Product Size Changeover
Quickly adjust the end-stop on automated assembly lines when switching between different product sizes, leveraging the 40 mm trim range for rapid setup.
High-Force Positioning
Utilize the 28274N push force to move heavy pallets or fixtures, relying on the SUS304 rod for durability in harsh industrial environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX170-40S the Right Cylinder?
Select this 200 mm bore cylinder when an application demands extreme force alongside positional flexibility; if lower thrust is acceptable, stepping down to a 160 mm bore yields 18095N of push force at 0.9 MPa. The adjustable 130-170 mm travel window is perfect for product-size changeovers on a line, providing a variable end-stop that a fixed-stroke SAI cylinder cannot offer. Keep in mind the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding, consider an SAIL or BSAI cylinder.
Because this is a large-bore cylinder with a 170 mm stroke, the 40 mm diameter rod and M36x2 thread provide substantial rigidity against side loading, though any long unsupported stroke still requires an external guide. To ensure exact ISO 15552 replacement compatibility, verify the 200 mm bore, 170 mm stroke, 40 mm adjustment, PT port thread, and the -S magnet requirement. Mounting options are limited to the SAIJ subset: 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 SAIJ200BX170-40S FAQ
At an operating pressure of 0.9 MPa, this 200 mm bore cylinder generates a push force of 28274N and a pull force of 15080N. The maximum thrust at 1.0 MPa is 3204 kgf.
The rear adjuster screw acts as a mechanical stop that shortens the effective stroke from its 170 mm nominal length. This provides a usable travel window of 130-170 mm, allowing you to fine-tune the end position at commissioning, but it does not lock the load without continuous air pressure.
