About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-20S
The AirTAC SAIJ160X45-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 10053N pull force at 0.5MPa and uses a PT tapered G3/4 port. With a 45mm nominal stroke and a 20mm adjustment range, you can fine-tune the usable travel window down to 25mm during commissioning without adding external stops.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel provides sensor grooves on both sides. Remember the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-20S Is Used
Press Fit Tuning
Dial in the exact 25-45mm insertion depth for varying product sizes on an assembly line without swapping out the entire cylinder.
Machine Changeover
Quickly reset the end-stop position during product family transitions using the rear adjuster screw to accommodate new part dimensions.
Heavy Forming End-Stop
Leverage the 10053N pull force for heavy-duty forming operations while precisely controlling the retract position via the rear stopper.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-20S the Right Cylinder?
Choose this 160mm bore when 10053N pull at 0.5MPa is required, or step down to the 125mm bore offering 5734N pull if your force needs are lower. The adjustable stroke is ideal for machine changeovers where the exact end-of-travel position varies. For load-holding without continuous air pressure, use an external rod lock or select the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 160mm bore, 45mm stroke, 20mm adjustment, PT G3/4 port, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Although the 40mm rod and M36x2 thread handle high side loads, any stroke over 300mm requires an external guide.
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 SAIJ160BX45-20S FAQ
At 0.5MPa operating pressure, this 160mm bore cylinder provides 10053N of pull force and 14074N of push force at 0.7MPa.
The rear adjuster screw lets you shorten the effective travel from the 45mm nominal stroke down to 25mm, creating a 25-45mm usable window for fine-tuning end positions without external stops.
