About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-40
The AirTAC SAIJ160X75-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 14074N of push force at 0.7MPa and incorporates a SUS304 stainless steel rod for superior corrosion resistance. By turning the external stopper screw, you can fine-tune the effective travel window down from the 75mm nominal stroke to a 35mm minimum, achieving precise end-position calibration without swapping hardware.
This 160mm bore unit uses PT tapered ports and operates at 30-500mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster functions purely as a mechanical travel stop to set the retraction endpoint, meaning it will not hold a load if air pressure is lost.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-40 Is Used
Press Fit Tuning
Dial in the exact insertion depth of heavy bearings on a press line by trimming the stroke from 75mm down to 35mm during setup.
Product Changeover
Adjust the retraction endpoint on the fly when switching a packaging line to a different pallet height without changing the cylinder.
Heavy Material Handling
Move heavy workpieces with 14074N of force while using the rear stopper to guarantee consistent mechanical positioning against hard stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX75-40 the Right Cylinder?
Choose this adjustable model when your assembly requires exact end-position tuning during commissioning or frequent product-size changeovers, avoiding the need to bolt on external stops or buy multiple fixed-stroke SAI cylinders. If your application needs less force, stepping down to a 125mm bore yields 8590N at 0.7MPa. For load-holding without live air pressure, this cylinder is insufficient; you must specify an SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock.
To match this ISO 15552 cylinder for a direct replacement, verify the 160mm bore, 75mm nominal stroke, 40mm adjustment range, PT G3/4 port thread, and SUS304 (B) rod material. Because the 75mm stroke is relatively short for this large bore, side-load risks are minimal, but heavy loads should still use an external guide.
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 SAIJ160BX75-40 FAQ
At 0.7MPa operating pressure, this 160mm bore cylinder generates 14074N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 75mm nominal stroke down to a 35mm effective travel window. It sets the retraction endpoint for fine-tuning but does not lock the load without live air pressure.
