About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-30S
The AirTAC SAIJ160X185-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 155 to 185 mm usable travel window, allowing you to dial back the nominal 185 mm stroke by up to 30 mm during commissioning. Delivering 10053 N of push force at 0.5 MPa, this carbon-rod actuator handles heavy loads with a 40 mm rod and M36x2 thread. The extruded aluminum barrel features sensor grooves on both sides, and the -S magnet enables precise position detection with AirTAC CMSE reed and DMSE electronic switches.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops when tuning end positions. The rear adjuster acts strictly as a travel stop to set deceleration, not a lock, meaning it cannot hold the load without live air. For true fail-safe load holding, consider the SAIL or BSAI series. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-30S Is Used
Machine Changeovers
Fine-tune the 155-185 mm travel window on the fly to accommodate different product sizes without swapping actuators or adding external mechanical stops.
Heavy Pressing
Leverage the 10053 N push force at 0.5 MPa for heavy pressing or forming tasks, using the rear stopper to precisely set the final position.
Assembly Stations
Utilize the dual sensor grooves and CMSE/DMSE compatibility to verify end positions in automated assembly lines, adjusting the stroke as tooling wears.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X185-30S the Right Cylinder?
Select this 160 mm bore actuator when an application requires 10053 N of push force at 0.5 MPa with a variable end-stop. If your setup needs less force, stepping down to a 125 mm bore yields 6136 N; if you need more power, a 200 mm bore provides 15708 N. Choose this adjustable model over a fixed SAI cylinder when machine changeovers require fine end-position tuning without mechanical rebuilds. Because this is a 185 mm stroke, ensure external guides support any heavy side loads to prevent rod binding.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 160 mm bore, 185 mm stroke, 30 mm adjustment range, PT tapered port threads, and the -S magnet option. The standard carbon steel rod and TPU seals suit general industrial environments, while the 30-500 mm/s speed range ensures smooth operation.

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 SAIJ160X185-30S FAQ
The rear adjuster allows you to shorten the 185 mm nominal stroke by up to 30 mm, creating a usable travel window of 155 to 185 mm. It functions as a mechanical stop to set the end position and deceleration, but it does not lock or hold the load without continuous air pressure.
At a 0.5 MPa operating pressure, the SAIJ160X185-30-S generates 10053 N of push force and 9425 N of pull force. It can reach up to 18095 N of push force at 0.9 MPa.
