About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-100S
The AirTAC SAIJ160X120-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 20 to 120 mm, allowing you to dial back the 120 mm nominal stroke by up to 100 mm during commissioning. Belonging to the 160 mm bore class, it generates 14074 N of push force at 0.7 MPa and 18095 N at 0.9 MPa, making it suited for heavy-duty positioning tasks.
This unit includes a standard carbon steel rod and a -S magnet for position sensing. You can mount CMSE reed or DMSE electronic sensors directly into the extruded aluminum barrel grooves on both sides. It uses PT tapered G3/4 ports and relies on variable air cushions at both ends to decelerate the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-100S Is Used
Heavy Press Tuning
Dial in the exact 20 to 120 mm travel window during machine setup to apply precise clamping force without swapping out the entire cylinder.
Product Changeover
Quickly adjust the retract end-stop on a packaging line to accommodate varying product lengths on the fly, reducing downtime between runs.
Assembly Station Setup
Fine-tune the end position at commissioning to perfect the mating alignment of heavy components, relying on the 40 mm rod for rigid support.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-100S the Right Cylinder?
Choose this 160 mm bore cylinder when you need substantial thrust, such as 10053 N at 0.5 MPa, and highly flexible end-position tuning without machining external stopper blocks. If your application requires less force, stepping down to the 125 mm bore yields 6136 N at 0.5 MPa. The rear adjuster screw acts purely as a travel stop to fine-tune the retract position; it does not hold the load without live air. For true load-holding on power loss, select an SAIL pilot-lock or BSAI clamp-lock cylinder instead. Because the nominal stroke is 120 mm, an external guide is not strictly required, but the 40 mm rod diameter and M36x2 thread handle high side loads well if minor misalignment exists. This SAIJ configuration is dimensionally interchangeable per ISO 15552, featuring PT tapered G3/4 ports, a -S magnet, and mounting options limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160X120-100S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw lets you trim the effective travel back by up to 100 mm from the 120 mm nominal stroke, creating a 20 to 120 mm usable travel window. This stopper only sets the end position; it does not lock the load without continuous air pressure.
