About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-40
The AirTAC SAIJ160X160-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a 120-160 mm usable travel window from its 160 mm nominal stroke. In the 160 mm bore class, it generates 14074 N of push force at 0.7 MPa and up to 18095 N at 0.9 MPa, making it a robust choice for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch mounting.\n\nThis adjustable variant allows operators to fine-tune the retract end-position at commissioning without adding external stops. It features a 40 mm carbon steel rod with an M36x2 thread, providing substantial rigidity, though long unsupported strokes still require an external guide. The mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. Standard seals are TPU, with Viton H available for high-temperature environments.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-40 Is Used
Heavy Machinery Positioning
Dial in the exact retract distance for large metal fabrication presses, allowing quick adaptation to different die sizes without external stopper blocks.
Assembly Line Changeover
Fine-tune the end-of-stroke position during product family transitions, reducing setup time and ensuring components are seated perfectly every time.
Material Handling Stops
Adjust the pusher stroke on the fly to accommodate varying pallet widths in automated packaging lines, ensuring precise alignment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-40 the Right Cylinder?
Choose this 160 mm bore if your application requires up to 14074 N of thrust at 0.5 MPa; stepping down to a 125 mm bore yields 8590 N, while moving up to 200 mm provides 21991 N. An adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for product changeovers or precise machine setup. When matching ISO 15552 replacements, specify the 160 mm bore, 160 mm stroke, 40 mm adjustment, PT tapered ports, and the desired mounting kit. Because the stroke is under 300 mm, side-load stress is moderate, but the heavy mass still benefits from a guide. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series.
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 SAIJ160X160-40 FAQ
At 0.7 MPa, the 160 mm bore provides 14074 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw lets you shorten the effective travel from the 160 mm nominal stroke down to 120 mm, creating a 120-160 mm adjustable window. It acts as a physical stop to decelerate the load and is not a lock.
