About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-10
The AirTAC SAIJ160X45-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 18095N at 0.9 MPa. It features a robust 40mm SUS304 stainless steel rod and PT tapered ports. By integrating an external adjusting stopper, this model allows you to fine-tune the retract end position, creating a precise 35-45mm usable travel window from its 45mm nominal stroke.
This adjustable design eliminates the need to swap cylinders or add external stops during commissioning. The extruded aluminum barrel includes sensor grooves on both sides for straightforward positioning feedback. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air pressure; for dead-air locking, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-10 Is Used
Heavy Press Tuning
Dial in the exact 35-45mm pressing depth during machine commissioning to accommodate material thickness variations without changing the cylinder.
Product Changeover
Quickly adjust the retract end-stop on a packaging line when switching to a new product size, minimizing downtime and avoiding external stop hardware.
High-Force Positioning
Leverage the 18095N thrust capacity to move heavy assemblies into a precise final position, using the 10mm adjustment window to perfect the endpoint.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-10 the Right Cylinder?
Choose this 160mm bore when an 80mm cylinder (providing 4523N push at 0.9 MPa) cannot meet your force requirements, or step down if you do not need the full 18095N output. An adjustable stroke is ideal for applications requiring variable end-stops or precise setup tuning without buying a fixed-stroke SAI cylinder. To match this ISO 15552 footprint exactly, specify the 160mm bore, 45mm stroke, 10mm adjustment, PT ports, and your required mounting style.
Although the stroke is short, the 40mm SUS304 rod handles high side loads well, but any application with long unsupported travel still requires an external guide. The SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Operating speed for this bore is 30-500 mm/s.
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 SAIJ160BX45-10 FAQ
At 0.9 MPa operating pressure, this 160mm bore cylinder provides a push force of 18095N and a pull force of 9425N. It achieves a maximum push force of 10053N at 0.5 MPa.
The rear adjuster acts as a mechanical stop that trims the effective stroke back by up to 10mm. This creates a usable travel window of 35-45mm from the 45mm nominal stroke, allowing precise end-position tuning at commissioning without replacing the cylinder.
