About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-30S
The AirTAC SAIJ160X450-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. It provides a usable travel window of 420-450 mm, letting you dial back the 450 mm nominal stroke by up to 30 mm during commissioning without adding external stops. In the 160 mm bore class, it delivers 10053 N of push force and 9425 N of pull force at 0.5 MPa.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for electronic DMSE or reed CMSE position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, and the PT tapered port threads match the G3/4 interface. It supports the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and relies on adjustable air cushions at both ends to decelerate heavy 30-500 mm/s loads.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-30S Is Used
Heavy Press Tuning
Dial in the exact 420-450 mm end position during machine setup to accommodate varying material thicknesses without physically remounting the cylinder.
Product Changeover
Quickly adapt the retract stroke by up to 30 mm on a packaging line when switching between different product sizes, minimizing downtime.
Washdown Actuation
Leverage the SUS304 stainless steel rod for robust performance in food or chemical processing environments requiring frequent washdowns.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-30S the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore (providing 2513 N push at 0.5 MPa) is insufficient, but a 200 mm bore is too large. The 30 mm adjustment range is ideal for product changeovers requiring precise end-position tuning rather than swapping a fixed-stroke SAI cylinder. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ does not hold position without live air, so use a SAIL or BSAI cylinder for load-holding without pressure.
For a true ISO 15552 interchangeable replacement, match the 160 mm bore, 450 mm stroke, 30 mm adjustment, G3/4 PT ports, SUS304 rod, and the -S magnet. Because the 450 mm stroke is relatively long, the 40 mm rod diameter still requires an external guide to prevent excessive side-loading on the unsupported piston rod.
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 SAIJ160BX450-30S FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 2050 kgf.
A rear external stopper screw lets you shorten the 450 mm nominal stroke by up to 30 mm, creating a 420-450 mm adjustable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
