About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-100
The AirTAC SAIJ160X230-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from the 230 mm nominal stroke. This creates a highly versatile 130-230 mm usable window, letting you dial in the exact end-position at commissioning without swapping out the unit. It delivers substantial thrust, pushing with 10053 N and pulling with 9425 N at 0.5 MPa, making it suitable for heavy-duty positioning.
This specific SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features a PT tapered port thread. The 40 mm rod diameter and M36x2 thread provide excellent side-load capacity, though an external guide is still recommended for optimal performance. The rear adjuster acts purely as a mechanical stop to set the retract position and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-100 Is Used
Heavy-Duty Press Changeover
Dial in the 130-230 mm travel window on the fly to accommodate different material thicknesses during production line changeovers.
Variable End-Stop Positioning
Replace fixed external stops with the integrated rear adjuster to fine-tune the retract distance during machine commissioning.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for heavy thrust applications where standard carbon steel rods would degrade.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-100 the Right Cylinder?
Choose this 160 mm bore when your application requires heavy force that exceeds the 6136 N push of the neighboring 125 mm bore at 0.5 MPa. The 100 mm adjustment range is ideal for machinery that undergoes frequent product-size changeovers, allowing operators to reposition the end-stop quickly without fabricating new external stops. If you need fixed travel without on-the-fly adjustments, the standard SAI cylinder is a simpler alternative.
Because the nominal stroke is 230 mm, you do not need external side-load guidance for purely axial loads, but always ensure the load is properly supported. Remember that the rear adjuster and air cushions only decelerate the travel end; they do not lock the load. If your application requires true position holding without live air, consider the AirTAC SAIL or BSAI clamp-lock series. This model is dimensionally interchangeable per ISO 15552, features a PT port, and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX230-100 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear mechanical stopper lets you shorten the 230 mm nominal stroke by up to 100 mm, creating a usable travel window of 130 to 230 mm. The adjuster sets the retract end-position but does not act as a lock to hold the load without air pressure.
