About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-20
The AirTAC SAIJ160X65-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 65 mm nominal stroke by up to 20 mm for a precise 45-65 mm usable travel window. It delivers a substantial 10053 N pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. This configuration features a SUS304 stainless steel rod for superior corrosion resistance and PT tapered port threads.
Unlike a fixed-stroke SAI cylinder, this rear stopper screw lets you fine-tune the retract end-position during commissioning or product changeover without adding external stops. The adjuster acts purely as a travel stop and does not hold the load without live air pressure. For load-holding without continuous air supply, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-20 Is Used
Heavy Press Tuning
Dial in the exact 45-65 mm retract position on heavy metal forming presses to accommodate varying material thicknesses without external spacers.
Assembly Line Changeover
Rapidly adjust end-stops during product family changeovers on automated lines, using the rear screw to set new locking depths on the fly.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for heavy clamping or positioning tasks in washdown or chemical-heavy manufacturing zones.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-20 the Right Cylinder?
Select this 160 mm bore when a 125 mm bore (providing 6136 N pull at 0.5 MPa) is insufficient for your heavy load requirements. The adjustable 45-65 mm travel window is highly advantageous on machinery requiring variable retract end-stops for different product sizes, avoiding the need to physically swap cylinders during changeovers. To match this exact configuration for an ISO 15552 replacement, specify: 160 mm bore, 65 mm stroke, 20 mm adjustment, PT ports, SUS304 (B) rod material, and no magnet.
Because the stroke is relatively short at 65 mm, the 40 mm diameter rod and M36x2 thread provide exceptional rigidity, easily handling high side loads without requiring an external guide. Mounting options are restricted to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ160BX65-20 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating a 45-65 mm usable travel window. It acts as a mechanical stop to fine-tune the retract position at commissioning without swapping the cylinder.
At 0.5 MPa operating pressure, it provides 10053 N of pull force and 14074 N of push force. The maximum operating pressure is 1.0 MPa, and the operating speed range is 30-500 mm/s.
