About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-30S
The AirTAC SAIJ160X115-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the retract end position during commissioning. It provides a usable travel window of 85 to 115 mm, letting you shorten the effective stroke by up to 30 mm without swapping hardware or adding external stops. Featuring a 160 mm bore, 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.
This unit includes a magnet for CMSE reed and DMSE electronic sensors, which seat directly into the dual-side sensor grooves on the extruded aluminum barrel. It uses a robust 40 mm carbon steel rod with an M36x2 thread, handling high side loads well, though any long unsupported travel still requires an external guide. The mounting interface is dimensionally interchangeable with ISO 15552 cylinders, utilizing a reduced set of attachments (Basic, FA, LB, TC, FTC, TCM1, TCM2) that omits FB, CA, CB, and CR brackets.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-30S Is Used
Heavy Press Fine-Tuning
Dial in the exact 85-115 mm retract position during heavy press commissioning to accommodate material thickness variations without external stopper blocks.
Product Size Changeovers
Quickly adjust the end-stop on packaging or conveyor lines when switching to different product sizes, using the 30 mm adjustment range to adapt the stroke on the fly.
Automated Assembly Stops
Set precise retraction limits for heavy automated assembly stations, leveraging the 18095 N push force at 0.9 MPa to move substantial jigs while fine-tuning the rest position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-30S the Right Cylinder?
Select this 160 mm bore cylinder when an application demands substantial force—stepping down to a 125 mm bore yields 8590 N of push force at 0.5 MPa, whereas this 160 mm model provides 10053 N at the same pressure. Choose the SAIJ adjustable variant over a fixed SAI cylinder when you need variable end-stops for machine setup or product-size changeovers. To match this ISO 15552 replacement exactly, specify: 160 mm bore, 115 mm stroke, 30 mm adjustment, PT tapered port threads, the appropriate mounting option, and the -S magnet.
Remember that the rear adjuster acts purely as a mechanical stop to set deceleration and travel limits; it does not hold the load without live air. For load-holding without continuous pressure, consider an AirTAC SAIL, BSAI, or an external pilot-operated check valve. Since the 40 mm rod and M36x2 thread carry significant side loads, ensure proper guiding for your mechanics.

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 SAIJ160X115-30S FAQ
It features a rear adjuster screw that lets you shorten the nominal 115 mm stroke by up to 30 mm, creating an 85-115 mm usable travel window. This allows precise end-position tuning at commissioning or during product changeovers without replacing the cylinder.
At 0.7 MPa, the push force is 14074 N and the pull force is 9425 N. At 0.9 MPa, it delivers 18095 N of push force, providing substantial power for heavy-duty applications.
