Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-20S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 145mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-20S
The AirTAC SAIJ160X145-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers robust thrust, pushing 10053 N and pulling 9425 N at 0.5 MPa. By turning the rear screw, you can trim the effective travel back by up to 20 mm, creating a precise 125-145 mm usable stroke window without swapping out the actuator. This profile design features an extruded aluminum barrel with sensor grooves on both sides, and the -S suffix means it includes a magnet for position detection.
This 160 mm bore actuator uses a G3/4 PT port and a 40 mm carbon steel rod with an M36x2 thread, providing high structural rigidity. It supports variable air cushions at both ends to manage kinetic energy, and operates at speeds of 30-500 mm/s. The rear stopper sets the end position, but it does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-20S Is Used
Press Stroke Calibration
Dial in the exact 125-145 mm end position during machine commissioning to accommodate material thickness variations without adding external hard stops.
Heavy Product Changeover
Quickly adjust the rear stopper by up to 20 mm when switching production lines to different sized parts, leveraging the 10053 N thrust for robust actuation.
Position Feedback Setup
Utilize the integrated magnet with AirTAC CMSE reed or DMSE electronic sensors to confirm the adjusted end-of-stroke position in automated control systems.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-20S the Right Cylinder?
Choose this 160 mm bore when an application requires heavy thrust, such as 10053 N push force at 0.5 MPa, but demands finer end-position tuning than a fixed-stroke SAI offers. If your force requirements are lower, stepping down to a 125 mm bore yields 6136 N push force. The adjustable 125-145 mm travel window is ideal for machine setups requiring on-the-fly end-stop calibration during product changeovers. Because the stroke is 145 mm, side-load risks are manageable, but always ensure external guides support the load. For load-holding without continuous air pressure, select a SAIL or BSAI model, as the SAIJ rear adjuster functions only as a travel stop, not a brake.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 160 mm bore, 145 mm nominal stroke, 20 mm adjustment range, G3/4 PT port, and the -S magnet option. The compatible mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations.

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 SAIJ160X145-20S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides a push force of 10053 N and a pull force of 9425 N. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf of push force.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 145 mm nominal stroke by up to 20 mm. This creates a usable travel window of 125-145 mm for fine-tuning the retract end position at commissioning. It is a stop, not a lock, and cannot hold the load without air pressure.
