About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-50
The AirTAC SAIJ160X190-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for heavy-duty pneumatics. It features a 160 mm bore generating 14074 N of push force at 0.7 MPa, utilizing a PT tapered port thread and a 40 mm carbon steel rod. By incorporating a 50 mm adjustment range, this model provides a usable travel window between 140 mm and 190 mm, allowing technicians to dial in the exact retract end-position during commissioning.
This adjustable-stroke design eliminates the need to swap out the entire cylinder or bolt on external stops when fine-tuning machine movements. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement, while the variable air cushions at both ends manage deceleration. It is important to note that the rear adjuster functions strictly as a travel stop, not a load lock; maintaining position without live air requires an external rod lock or a related SAIL pneumatic lock cylinder.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-50 Is Used
Heavy-Duty Press Tuning
Dial in the exact 140 to 190 mm pressing depth during commissioning without swapping cylinders, ensuring perfect force application for large assembly tasks.
Product Line Changeover
Quickly adjust the retract end-stop by up to 50 mm to accommodate different product sizes on the same fixture, minimizing downtime between production runs.
Large Fixture Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy industrial pallets, using the rear stopper to precisely set the retracted resting position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-50 the Right Cylinder?
Selecting this 160 mm bore cylinder is ideal when an application demands high thrust, such as 18095 N push force at 0.9 MPa, combined with variable end-stop positioning. If the workload requires less force, stepping down to a 125 mm bore yields 11045 N of push at 0.9 MPa, whereas moving up to a 200 mm bore provides 28274 N. The 50 mm adjustment window is particularly advantageous for product changeovers, enabling rapid setup modifications without replacing the cylinder.
For an exact ISO 15552 replacement match, verify the 160 mm bore, 190 mm nominal stroke, 50 mm adjustment code, PT port threads, and standard carbon steel rod. Because this unit lacks the -S magnet option, it will not work with CMSE or DMSE electronic sensors without modification. Furthermore, the 40 mm rod and M36x2 thread provide substantial side-load resistance, but any application approaching the 190 mm stroke limit should still employ an external guide to prevent premature seal wear.
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 SAIJ160X190-50 FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. When operating at 0.9 MPa, the push force increases to 18095 N, making it suitable for heavy-load applications.
The rear adjuster acts as a mechanical stopper that allows you to shorten the effective stroke by up to 50 mm. This creates a usable travel window of 140 to 190 mm, enabling fine-tuning of the end position without changing the cylinder.
