About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-20
The AirTAC SAIJ160X230-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract position. With a nominal 230 mm stroke and a 20 mm adjustment range, the usable travel window is 210-230 mm. This enables precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
Belonging to the 160 mm bore class, it delivers substantial thrust, pushing 18095 N at 0.9 MPa. This specific SKU is configured with a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-20 Is Used
Machine Setup & Changeover
Dial in the 210-230 mm travel window during product size transitions without machining new external stopper blocks.
Heavy Pressing Operations
Leverage the 18095 N push force at 0.9 MPa for heavy-duty assembly tasks while fine-tuning the final end position.
Position Calibration
Use the rear adjuster screw to precisely set the retract stroke limit during initial commissioning of automated equipment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-20 the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires up to 18095 N of push force at 0.9 MPa. If you need less force, stepping down to the 125 mm bore yields 11045 N at 0.9 MPa. The adjustable stroke is ideal for machine setups requiring a variable end-stop during product changeovers, unlike a fixed-stroke SAI cylinder. Remember that the rear adjuster is a travel stop, not a lock; for load-holding without live air pressure, consider an SAIL or BSAI cylinder. To match this ISO 15552 replacement exactly, specify bore 160, stroke 230, 20 mm adjustment, PT port, and no magnet.
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 SAIJ160BX230-20 FAQ
The 160 mm bore generates a push force of 14074 N at 0.7 MPa and 18095 N at 0.9 MPa, with a pull force of 9425 N at 0.7 MPa.
The rear adjuster acts as a stopper that lets you shorten the effective travel from the nominal 230 mm down to 210 mm, providing a 210-230 mm usable window without replacing the cylinder.
