About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-20
The AirTAC SAIJ160X190-20 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a 170-190 mm usable travel window by allowing you to dial back the 190 mm nominal stroke by up to 20 mm during commissioning. In the 160 mm bore class, it generates 10053 N of push force and 9425 N of pull force at 0.5 MPa, making it suited for heavy-duty positioning tasks.
This model uses a robust 40 mm carbon steel piston rod with an M36x2 thread, offering high resistance to bending under heavy loads. It features adjustable air cushions at both ends to absorb kinetic energy, but the rear adjuster acts only as a travel stop—it does not hold the load without live air pressure. For position holding without continuous air, an external rod lock or AirTAC SAIL cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-20 Is Used
Heavy-Duty Press Tuning
Dial in the exact end-of-stroke position for a large press during setup, trimming the travel by up to 20 mm to accommodate different material thicknesses without changing the cylinder.
Product Changeover Stops
Quickly adjust the retract end-stop on a packaging line when switching to a new product size, using the rear screw to fine-tune the 170-190 mm travel window.
Assembly Line Positioning
Position heavy components accurately on an assembly line, relying on the 10053 N push force and adjustable end-stop to perfect the motion path during commissioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-20 the Right Cylinder?
Choose the SAIJ160X190-20 when your application requires precise end-position tuning without adding external stops or swapping cylinders. If you need slightly less force, stepping down to a 125 mm bore yields 6136 N of push force at 0.5 MPa; stepping up to a 200 mm bore provides 15708 N. This 160 mm bore operates at speeds of 30-500 mm/s and uses a G3/4 PT port.
Because the 190 mm stroke approaches the mid-range for this bore size, ensure your mounting configuration supports the load adequately. The SAIJ series supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. When replacing an ISO 15552 cylinder, match the 160 mm bore, 190 mm stroke, 20 mm adjustment, G3/4 port, and mounting hardware. For strokes of 300 mm or more, an external guide is recommended to prevent rod side-loading, though this 190 mm travel is well within standard limits.

- ✓ 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 SAIJ160X190-20 FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 20 mm. This creates a 170-190 mm usable travel window for fine-tuning the end position at commissioning without replacing the cylinder.
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates a push force of 10053 N and a pull force of 9425 N. It can achieve up to 14074 N of push force at 0.7 MPa.
