About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX180-20
The AirTAC SAIJ200X180-20 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a nominal 180 mm stroke that can be fine-tuned down by up to 20 mm via a rear adjusting screw. This yields a precise 160-180 mm usable travel window, allowing you to dial in the exact retract end position at commissioning without swapping out the cylinder or adding external stops. In the 200 mm bore class, it generates a substantial 15708 N of push force and 15080 N of pull force at 0.5 MPa, peaking at a 3204 kgf capacity at 1.0 MPa.
This configuration features a SUS304 stainless steel rod (material code B) for superior corrosion resistance, paired with PT tapered port threads and a G3/4 air supply. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. While the rear adjuster and variable air cushions effectively set and decelerate the travel end, neither will hold a load without live air pressure; for positive load-holding, consider an external rod lock or the AirTAC SAIL/BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX180-20 Is Used
Heavy Machinery Setup
Fine-tunes the 160-180 mm retract position on large presses and heavy material handlers during initial commissioning without external stopper hardware.
Product Line Changeover
Allows operators to quickly dial back the stroke by up to 20 mm to accommodate different sized products on an automated assembly line.
Corrosive Environment Actuation
Leverages the SUS304 stainless steel rod to deliver up to 15708 N of thrust in washdown or corrosive manufacturing settings requiring exact end-position tuning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX180-20 the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires extreme thrust—up to 15708 N at 0.5 MPa—and you need the flexibility to trim the retract stroke within a 160-180 mm window for product changeovers. If your force requirements are lower, stepping down to the 160 mm bore yields 10053 N of push force at 0.5 MPa, which may save space and air consumption. Because this is an adjustable-stroke model rather than a fixed-stroke SAI cylinder, it is ideal for machine setups where the exact end-of-stroke position must be tuned on-site. To ensure a seamless ISO 15552 replacement, verify the 180 mm stroke, 20 mm adjustment range, G3/4 PT ports, and your required mounting style. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR options. Although the stroke is under 300 mm, the massive 40 mm rod and M36x2 thread handle high side loads, though an external guide is still recommended for heavy off-center loads.
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 SAIJ200BX180-20 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf of thrust.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective stroke from its 180 mm nominal length down to 160 mm. This creates a 160-180 mm adjustable travel window for fine-tuning the end position without altering the cylinder mounting.
