About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-75S
The AirTAC SAIJ160X115-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust thrust for heavy-duty automation. It yields 10053N push and 9425N pull force at 0.5 MPa. The integrated -75 adjustment code allows you to trim the nominal 115mm stroke back by up to 75mm, creating a highly versatile 40-115mm usable travel window for precise end-position tuning.
This model features a standard carbon steel piston rod and a PT tapered port. Because it carries the -S magnet option, it directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side extruded aluminum barrel grooves. The rear adjuster functions strictly as a travel stop to dial in the retraction point during product changeovers, not as a locking mechanism to hold loads without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-75S Is Used
Heavy Press Tuning
Dial in the exact 40-115mm retraction point on heavy pressing assemblies during setup, ensuring perfect contact force without machining custom spacers.
Product Changeover
Quickly adjust the end-stop distance on packaging lines when switching between different product sizes, minimizing machine downtime.
Variable End Positioning
Provide a customizable travel window for automated heavy-load handling where the exact retraction distance must be tweaked on the fly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-75S the Right Cylinder?
Select this 160mm bore cylinder when an application demands high force combined with variable end-stops, stepping up from a 125mm bore that provides 6136N push force at 0.5 MPa. The adjustable stroke is chosen over a fixed SAI cylinder when commissioning requires fine-tuning the retraction point without adding external stops or swapping the actuator. To match this ISO 15552 footprint for a direct replacement, verify the 115mm stroke, 75mm adjustment range, PT port thread, and the -S magnet requirement.
Although the 115mm stroke is relatively short for this bore size, always ensure the load is guided to prevent excessive side-loading on the 40mm rod. For applications requiring the load to be held securely in place without continuous compressed air, a standard SAIJ is insufficient; instead, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. Mounting options for this series include 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 SAIJ160X115-75S FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 115mm stroke by up to 75mm, resulting in a usable travel window of 40-115mm. It only sets the end position and does not lock the load without live air.
