About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-40
The AirTAC SAIJ160X65-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 65 mm stroke by up to 40 mm. This yields a highly flexible usable travel window of 25 to 65 mm, letting you fine-tune the retract end-position during commissioning without swapping out the cylinder or adding external stops. It delivers robust performance, generating 14074 N of push force at 0.7 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and carries a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the cylinder operates at speeds of 30-500 mm/s. Remember that the rear adjuster acts purely as a travel stop to set deceleration, not as a lock; it will not hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-40 Is Used
Variable End-Stop Machining
Dial in the exact retract distance for machining operations or clamping stations where material thickness varies, utilizing the 25-65 mm travel window.
Machine Setup & Changeover
Eliminate the need to physically swap cylinders during product line changeovers by simply turning the rear adjuster screw to shorten the stroke.
Heavy-Duty Positioning
Leverage the 14074 N push force at 0.7 MPa for heavy workpiece positioning, relying on the stopper to set the exact end-point without external hardware.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-40 the Right Cylinder?
Choose this 160 mm bore when an application requires substantial thrust—such as 10053 N push at 0.5 MPa—but demands on-the-fly end-position tuning for product changeovers. If your process only needs a fixed 65 mm stroke without commissioning adjustments, the standard SAI cylinder is a simpler choice. For load-holding without continuous air pressure, you must look outside this adjustable stopper to a SAIL pneumatic lock or an external pilot-operated check valve.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 65 mm stroke, 40 mm adjustment range, PT G3/4 port, and SUS304 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR foot and pivot brackets. Because the 40 mm adjustment range is large relative to the 65 mm stroke, ensure the moving load is properly guided to prevent side-loading the 40 mm rod during the shortest travel positions.

- ✓ 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 SAIJ160BX65-40 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 13235 N of pull force. It can deliver a maximum push of 18095 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to trim the 65 mm nominal stroke back by up to 40 mm. This provides a usable travel window of 25 to 65 mm, which can be fine-tuned during commissioning without changing the cylinder.
