About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-40S
The AirTAC SAIJ160X190-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 150 to 190 mm, letting you dial back the extend position by up to 40 mm during commissioning without adding external stops. In the 160 mm bore class, it delivers 14074 N of push force at 0.7 MPa.
This unit includes a magnetic piston for position detection and uses a PT G3/4 port. The extruded aluminum barrel offers sensor grooves on both sides for CMSE reed or DMSE solid-state switches. The standard carbon steel rod and M36x2 thread handle high side loads, while the rear adjuster acts purely as a travel stop, not a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-40S Is Used
Machine Setup Tuning
Dial in the exact 150-190 mm extend position during initial commissioning to align heavy clamping faces without machining custom spacers.
Product Size Changeover
Quickly adapt the end-stop on automated lines when switching between part sizes, using the 40 mm adjustment range to accommodate different material heights.
Heavy Forming End-Stop
Set a precise mechanical stop for high-force pressing or bending operations, relying on the 14074 N thrust at 0.7 MPa to drive the tooling.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-40S the Right Cylinder?
Choose this adjustable-stroke model when you need fine end-position tuning at machine setup or during product changeovers, avoiding the need to swap a fixed-stroke SAI cylinder. If you require less force, stepping down to the 125 mm bore yields 8590 N at 0.5 MPa. To replace an ISO 15552 cylinder, match the 160 mm bore, 190 mm stroke, 40 mm adjustment, PT G3/4 port, and -S magnet. For any application using 300 mm or more of stroke, adding an external guide is recommended to prevent rod binding under high side loads. Because the rear adjuster and air cushions only decelerate the load, use a SAIL or BSAI cylinder if you need to hold position without live air pressure.
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 SAIJ160X190-40S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. It reaches a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw lets you shorten the effective travel from the 190 mm nominal stroke down to 150 mm. This stopper only sets the end position and must not be used to hold a load without continuous air pressure.
