About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-50S
The AirTAC SAIJ160X160-50-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 160 mm stroke that can be dialed back by up to 50 mm, creating a precise 110-160 mm usable travel window for commissioning flexibility. Belonging to the 160 mm bore class, it delivers substantial thrust, pushing with 14074 N at 0.7 MPa.
This unit includes a magnet for position sensing and uses a carbon steel rod with a PT tapered port thread. The extruded aluminum barrel features sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. Mounting options cover the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-50S Is Used
Press Stroke Calibration
Dial in the exact 110-160 mm end position during initial machine commissioning to accommodate varying material thicknesses without physically replacing the actuator.
Product Line Changeover
Rapidly adjust the retract stop by up to 50 mm when switching the manufacturing line to a new product size, ensuring precise positioning without external stopper blocks.
Heavy Forming End-Stop
Leverage the 14074 N push force at 0.7 MPa for heavy-duty forming operations while using the built-in rear screw to set the final travel limit accurately.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-50S the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high thrust (14074 N push at 0.7 MPa) alongside variable end-stop positioning. The 50 mm rear adjuster allows you to fine-tune the retract position during machine setup or product changeover without swapping the cylinder or adding external stops. If your force requirements are lower, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, which might better suit mid-range tasks.
Because this is a 160 mm stroke unit, it does not require external side-load guides, but the robust 40 mm rod and M36x2 thread handle substantial mechanical stress. Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither will hold a load without live air pressure. For load-holding requirements without continuous air, consider the SAIL pneumatic lock or BSAI clamp-lock series. To match this ISO 15552 replacement, specify: 160 mm bore, 160 mm stroke, 50 mm adjustment, PT ports, and the -S magnet option.

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 SAIJ160X160-50S FAQ
The -50 code means the cylinder has a 50 mm adjustment range. By turning the rear screw, you can shorten the 160 mm nominal stroke, providing a usable travel window of 110-160 mm to fine-tune the end position without swapping the cylinder.
At a 0.7 MPa operating pressure, the SAIJ160X160-50-S generates 14074 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it achieves up to 18095 N of push force.
