About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-100
The AirTAC SAIJ160X150-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the 150 mm nominal travel back by up to 100 mm, creating a highly flexible 50-150 mm usable window. It delivers substantial thrust, pushing 18095 N at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
The rear adjustment screw acts as a hard mechanical stop to fine-tune the retract end-position during commissioning or product changeovers without swapping the cylinder. It utilizes a standard carbon steel rod with PT tapered ports, and the extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic sensors.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-100 Is Used
Variable Pressing Operations
Dial in the exact 50-150 mm stroke length during machine setup to accommodate different material thicknesses or compression depths without physically changing the cylinder.
Heavy Product Changeover
Rapidly adjust the retract end-stop on a production line when switching between heavy product variants, leveraging the 18095 N push force for robust actuation.
Commissioning End-Tuning
Use the 100 mm rear adjuster screw to precisely set the final resting position during initial equipment commissioning, avoiding the need to bolt on secondary external stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-100 the Right Cylinder?
Select this 160 mm bore cylinder when an application demands heavy force within a specific 50-150 mm travel window, such as variable pressing or forming operations. If your process requires less force, stepping down to a 125 mm bore yields 11045 N of push force at 0.9 MPa, whereas moving up to a 200 mm bore provides 28274 N. Because the stroke is 150 mm, it remains under the 1500 mm maximum standard stroke limit, meaning no external side-load guide is strictly required here.
Choose this adjustable variant over a fixed-stroke SAI when you need on-the-fly end-position tuning without adding external stops. Remember that the rear adjuster only sets the travel end and the air cushions manage deceleration; neither holds the load without live air pressure. For true fail-safe load holding, integrate an external SAIL pneumatic lock, a BSAI clamp-lock cylinder, or a pilot-operated check valve. This unit is dimensionally interchangeable per ISO 15552 mounting interfaces, featuring a PT port thread, carbon steel rod, and no integrated magnet.

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 SAIJ160X150-100 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of push force and 14074 N of pull force. The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the 150 mm nominal stroke by up to 100 mm, providing a usable travel window of 50 to 150 mm. It sets the end position but does not lock or hold the load without continuous air pressure.
