About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-20S
The AirTAC SAIJ160X210-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 210 mm stroke by up to 20 mm. This yields a precise 190-210 mm usable travel window for commissioning without adding external stops. In the 160 mm bore class, it delivers substantial thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa.
This configuration features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a travel stop to decelerate the end-of-stroke position, so it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-20S Is Used
Heavy Press Tuning
Dial in the exact 190-210 mm end-stop during machine commissioning to accommodate material thickness variations without swapping tooling.
Product Changeover
Adjust the retract position on the fly to handle different package sizes on a heavy-duty handling line, utilizing the 20 mm travel window.
Assembly Station Setup
Fine-tune the clamping travel of large components, relying on the 14074 N push force and the SUS304 rod for durable operation.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-20S the Right Cylinder?
Select this adjustable-stroke model when an application requires exact end-position tuning during setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. If your process demands less force, stepping down to a 125 mm bore yields 8590 N of push force at 0.7 MPa; conversely, moving up to a 200 mm bore provides 21991 N.
To replace this cylinder on an ISO 15552 footprint, match the 160 mm bore, 210 mm stroke, 20 mm adjustment range, PT tapered port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 210 mm, ensure adequate external guiding to manage side loads over the travel distance.
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 SAIJ160 Adjustable Cylinder SAIJ160BX210-20S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At its maximum operating pressure of 1.0 MPa, it can deliver up to 18095 N of push force.
The rear adjuster screw lets you shorten the effective travel from the nominal 210 mm down to 190 mm, creating a 190-210 mm usable window. This stopper only sets the end position and decelerates the travel; it does not lock or hold the load without live air pressure.
