About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-10S
The AirTAC SAIJ160X210-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 200 to 210 mm usable travel window, allowing you to dial back the nominal 210 mm stroke by up to 10 mm during machine commissioning. It delivers substantial thrust, generating 10053 N of pull force at 0.5 MPa and 14074 N of push force at 0.7 MPa.
This unit includes a SUS304 stainless steel rod for corrosion resistance and a pre-installed magnet for position sensing. The barrel features sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid ports are PT tapered thread type, and the extruded aluminum design ensures it is dimensionally interchangeable with ISO 15552 cylinders without being a tie-rod type.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-10S Is Used
Heavy Press Fit Tuning
Dial in the exact 200 to 210 mm end-stop during press assembly commissioning to accommodate material variances without swapping cylinders.
Product Changeover Setup
Quickly adjust the retract end-position by up to 10 mm when switching between similar product sizes on a high-force production line.
Material Forming End-Stop
Use the rear stopper to precisely set the forming depth on heavy industrial machinery, relying on the 10053 N pull force for retraction.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-10S the Right Cylinder?
Choose this 160 mm bore when an application demands heavy force but requires precise end-position tuning without adding external stops. If you need slightly less force, stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa. The rear adjuster screw on this SAIJ model acts solely as a travel stop to fine-tune deceleration; it does not hold the load without live air. For true load-holding without pneumatic pressure, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 210 mm stroke, 10 mm adjustment range, PT G3/4 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, intentionally omitting FB, CA, CB, and CR brackets. Because the 210 mm stroke is relatively short for this large bore, side-load risks are minimal, but long unsupported strokes still require an external guide.

- ✓ 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 SAIJ160BX210-10S FAQ
The rear adjusting screw acts as an external stopper that lets you shorten the effective stroke by up to 10 mm. This creates a 200 to 210 mm usable travel window for fine-tuning end positions at commissioning without changing the cylinder.
At 0.5 MPa, it provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N. The maximum operating pressure is 1.0 MPa.
