About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-100S
The AirTAC SAIJ160X180-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning. With a nominal 180 mm stroke and a 100 mm adjustment range, it provides a highly flexible 80-180 mm usable travel window. This allows you to dial back the retract distance at commissioning or during product changeovers without swapping out the barrel or adding external stops.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical stop for deceleration and positioning; it is not a lock, so the cylinder cannot hold a load without live air pressure. For load-holding applications, consider the SAIL or BSAI series.

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 SAIJ160BX180-100S Is Used
Product Changeover Dials
Quickly adjust the 80-180 mm travel window during packaging line changeovers to accommodate different carton sizes without changing hardware.
Heavy Press End-Stop
Fine-tune the final pressing position of a 10053 N assembly operation at commissioning, using the rear screw to avoid hard mechanical crashes.
Corrosive Forming Station
Leverage the SUS304 stainless steel rod and 160 mm bore thrust for reliable actuation in humid or washdown manufacturing environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-100S the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires substantial thrust—up to 10053 N at 0.5 MPa—and variable end-stops. The 100 mm adjustment range on this 180 mm stroke model is ideal for machines processing multiple product sizes, letting operators fine-tune the retract distance on the fly. Unlike a fixed-stroke SAI cylinder, this SAIJ variant removes the need for external spacers during setup. When replacing an ISO 15552 cylinder, match the 160 mm bore, 180 mm stroke, 100 mm adjuster, PT G3/8 ports, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Although the stroke is under 300 mm, the heavy 40 mm rod and M36x2 thread handle high side loads, but an external guide is still recommended for heavy offset loads.
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 SAIJ160BX180-100S FAQ
The rear adjuster acts as a mechanical stopper that lets you shorten the effective stroke by up to 100 mm. This creates an 80-180 mm usable travel window for fine-tuning end positions without swapping cylinders. The adjuster only sets the travel end and does not lock or hold the load without live air pressure.
