About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-20S
The AirTAC SAIJ200X160-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end position by up to 20 mm. This creates a highly flexible 140-160 mm usable travel window, which is ideal for dialing in exact end-of-stroke positions during machine commissioning without adding external stops. It features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and a PT tapered port thread.
Delivering massive thrust, this 200 mm bore generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling up to 21991 N push at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and because this is an -S variant, it contains a magnet ready to interface with CMSE reed and DMSE solid-state switches. The robust 40 mm rod and M36x2 thread handle heavy loads, while the standard speed range is 30-500 mm/s.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-20S Is Used
Heavy Press Fine-Tuning
Dial in the exact 140-160 mm pressing depth during machine commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Changeover Setup
Quickly adjust the retract end-stop on automated heavy-duty assembly lines when switching to a new product size or format.
Large Fixture Positioning
Securely position large industrial jigs and fixtures, leveraging the 15708 N push force while making micro-adjustments to the final resting point.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-20S the Right Cylinder?
Choose this adjustable-stroke model when your setup requires precise end-position tuning on product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If you need to scale down force, the neighboring 160 mm bore offers 10053 N push at 0.5 MPa. For load-holding applications, note that the rear adjuster functions strictly as a travel stop and cannot hold a load without live air pressure; for true fail-safe holding, consider the SAIL pneumatic lock or BSAI clamp-lock series. As a dimensionally interchangeable ISO 15552 cylinder, it matches replacements using a 200 mm bore, 160 mm stroke, PT port, and -S magnet, but note the SAIJ mounting set omits FB, CA, CB, and CR options.
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 SAIJ200AX160-20S 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 0.7 MPa, the push force increases to 21991 N.
A rear external screw acts as a mechanical stopper, allowing you to shorten the 160 mm nominal stroke by up to 20 mm. This provides a usable travel window of 140-160 mm for precise end-position tuning.
