About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-40S
The AirTAC SAIJ160X180-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 140-180 mm. Built with a robust 40 mm carbon steel rod and M36x2 thread, it delivers substantial thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa. This bore size operates at a controlled speed range of 30-500 mm/s and features PT tapered ports sized at G3/4.
Because this is an adjustable-stroke variant rather than a fixed SAI model, you can dial in the retract end-position during commissioning without adding external stops. The integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic sensors, which seat neatly into the sensor grooves on both sides of the extruded aluminum barrel. Note that the rear adjuster functions strictly as a travel stop to set deceleration, not as a lock to hold the load without live air.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-40S Is Used
Heavy Press Tuning
Fine-tune the exact bottoming position of a heavy press during initial commissioning, using the 40 mm rear adjuster to perfect the crush depth without machining external spacers.
Product Size Changeover
Adapt a high-thrust diverting arm on a conveyor line for different package heights, dialing the stroke back within the 140-180 mm window to accommodate new product dimensions rapidly.
Machine Setup Calibration
Establish precise end-stops for heavy material handling equipment, leveraging the 14074 N push force at 0.7 MPa while making minute adjustments to the retract position on the factory floor.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-40S the Right Cylinder?
Select this 160 mm bore when an application requires heavy thrust that exceeds the 5497 N push force of a 100 mm cylinder, but does not demand the extreme 21991 N output of a 200 mm unit. The 40 mm adjustment range is particularly useful for product changeovers on heavy machinery, allowing operators to trim the stroke by up to 40 mm on the fly instead of physically swapping cylinders. For any setup utilizing this 180 mm stroke, ensure external guides support the load, as the large rod diameter cannot compensate for excessive side-loading on its own.
When matching ISO 15552 dimensions for a replacement, verify the 160 mm bore, 180 mm stroke, G3/4 PT ports, and the -S magnet requirement. Remember that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. If your application requires true load-holding without continuous air pressure, a plain SAIJ adjuster will not suffice; consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ160X180-40S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. At the maximum rated pressure of 1.0 MPa, it achieves a peak push force of 18095 N.
The rear adjuster acts as an external stopper that allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 140 to 180 mm. It sets the end position and deceleration point, but it is not a locking device and will not hold the load without live air pressure.
