About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX70-30
The AirTAC SAIJ160X70-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 30 mm. This specific SKU provides a usable 40-70 mm adjustable window, letting you dial in the exact retract position during commissioning without adding external stops. It delivers a robust 9425 N pull force at 0.5 MPa.
Built with a SUS304 stainless steel rod for maximum corrosion resistance, this 160 mm bore unit uses PT tapered ports and includes adjustable air cushions at both ends. The rear adjuster functions strictly as a travel stop to set the end position, meaning it will not hold the load if air pressure drops. For true load-holding without live air, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX70-30 Is Used
Press Stroke Tuning
Fine-tune the 40-70 mm travel window during machine commissioning to set precise clamping or pressing depths without swapping cylinders.
Product Changeover
Quickly adjust the retract stop on a production line to accommodate different material thicknesses or part sizes on the fly.
Heavy Forming Operations
Leverage the 160 mm bore's high thrust capacity for metal bending or forming tasks while using the rear screw to limit over-travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX70-30 the Right Cylinder?
Select this 160 mm bore cylinder when your application requires heavy thrust (up to 14074 N push at 0.7 MPa) combined with precise end-position tuning. You might step down to a 125 mm bore (offering 5734 N pull at 0.5 MPa) if your load is lighter, but the SAIJ160X70-30 is ideal when you need the extra force margin and a specific 40-70 mm travel window. The SUS304 rod and PT port threads are fixed on this configuration.
Because the stroke is relatively short at 70 mm, side-load stress on the rod is minimal, though an external guide is always recommended for heavy loads. This adjustable model is chosen over a fixed-stroke SAI when your machine setup requires variable end-stops for product changeovers. It uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

- ✓ 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 SAIJ160BX70-30 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 70 mm stroke by up to 30 mm, providing an effective 40-70 mm travel window. It sets the end position but does not lock or hold the load without live air pressure.
At 0.5 MPa, it provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
