About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-40
The AirTAC SAIJ160X190-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 190 mm travel that can be dialed back by up to 40 mm, giving you a precise 150 to 190 mm usable window for end-position tuning. In this 160 mm bore class, it delivers heavy thrust up to 18095 N pull at 0.9 MPa, making it suitable for high-force press operations.
This model features a robust 40 mm carbon steel piston rod with an M36x2 thread, providing excellent rigidity against side loads. The fluid porting uses PT tapered G3/4 threads, and the extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. You can fine-tune the retract position at commissioning without adding external physical stops or changing the cylinder itself.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-40 Is Used
Press Tonnage Tuning
Dial in the exact 150-190 mm crush distance during heavy assembly press setup without re-engineering the machine frame.
Product Line Changeover
Quickly retract the end-stop by up to 40 mm to accommodate a shorter workpiece variant on the same conveyor.
Heavy Forming End-Stop
Use the M36x2 threaded rod and rigid 160 mm body to set precise metal forming limits while absorbing high shock loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-40 the Right Cylinder?
Choose this 160 mm bore when you need substantial force—stepping down to a 125 mm bore drops your 0.9 MPa pull force to 11045 N, while stepping up to a 200 mm bore increases it to 28274 N. The adjustable stroke is ideal for heavy machine setup or product changeover, allowing you to trim the end position on the fly rather than swapping a fixed-stroke SAI cylinder. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider an external rod lock or the AirTAC SAIL series. To match this ISO 15552 replacement exactly, specify the 190 mm stroke, 40 mm adjustment, PT G3/4 ports, and standard carbon steel rod.
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 SAIJ160X190-40 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides 18095 N of pull force and 14074 N at 0.7 MPa. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster screw lets you shorten the 190 mm nominal stroke by up to 40 mm, creating a 150 to 190 mm travel window. It functions as a physical stop for end-position tuning and is not a load-holding lock.
