About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX185-100
The AirTAC SAIJ160X185-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. This built-in stopper eliminates the need to swap components or bolt on external stops when fine-tuning end positions.
This heavy-duty unit is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. It operates at speeds of 30-500mm/s and includes variable air cushions at both ends to decelerate the load. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder cannot hold a load without live air pressure.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX185-100 Is Used
Heavy Machinery Changeover
Quickly reconfigure the 85-185mm travel window on packaging or forming lines during product size transitions without changing out the entire actuator.
Commissioning Fine-Tuning
Dial in the exact retract end-position during machine setup using the rear stopper, avoiding the cost and complexity of adding external mechanical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX185-100 the Right Cylinder?
Choose this 160mm bore variant when an application requires high thrust (10053N at 0.5MPa) alongside a highly flexible 85-185mm travel range. If you need less force, stepping down to the 125mm bore yields 6136N at 0.5MPa, whereas moving up to the 200mm bore provides 15708N. The extensive 100mm adjustment range is ideal for product changeovers on a line, allowing variable end-stops without replacing the cylinder.
To match this exact ISO 15552 replacement, specify the 160mm bore, 185mm stroke, 100mm adjustment, PT port threads, and the SUS304 (B) rod material. Because the nominal stroke is under 300mm, side-load concerns are minimal, but long unsupported loads still require an external guide. For true load-holding without continuous air pressure, select a related SAIL or BSAI series cylinder instead of relying on the adjuster.
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 SAIJ160BX185-100 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke from 185mm down to a minimum of 85mm, creating a 100mm adjustable travel window.
At the maximum 1.0MPa pressure, the push force reaches 20000N.
