About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-40S
The AirTAC SAIJ160X700-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing 18095N at 0.9 MPa, while the external stopper screw allows you to fine-tune the effective travel window anywhere between 660 and 700 mm. This built-in adjustability eliminates the need to swap cylinders or add external stops during machine commissioning.
Equipped with a SUS304 stainless steel rod and a PT tapered port thread, this unit is tailored for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. Remember that the rear adjuster acts only as a travel stop, meaning live air pressure is required to hold the load in place.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-40S Is Used
Machine Setup & Changeover
Dial in the exact end-position during commissioning or product size changes, trimming the stroke by up to 40 mm without swapping the cylinder or adding external stops.
Heavy Pressing Operations
Leverage the 18095N push force at 0.9 MPa for heavy-duty forming or pressing tasks that require precise contact depth adjustment.
Long-Travel Positioning
Use the 660-700 mm adjustable travel window to position large fixtures accurately, relying on the SUS304 rod for durability in demanding industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-40S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires heavy thrust up to 18095N combined with precise end-position tuning. The 40 mm adjustment range is ideal for product changeovers on a line, letting you dial in the exact end-stop without changing the mounting footprint. If you need less force, stepping down to a 125 mm bore yields 11045N at 0.9 MPa. For load-holding without continuous air pressure, this cylinder is not a lock; you should pivot to the SAIL air-released lock or BSAI clamp-lock series.
Because the 700 mm stroke is substantial, the 40 mm rod diameter and M36x2 thread will carry significant side loads, but an external guide is still recommended to prevent rod binding over long unsupported travel. This SAIJ model shares the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. To replace an ISO 15552 cylinder, match the 160 mm bore, 700 mm stroke, 40 mm adjuster, G3/4 PT port, and the -S magnet requirement.
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 SAIJ160BX700-40S FAQ
This 160 mm bore cylinder provides 10053N of push force and 9425N of pull force at 0.5 MPa. At 0.9 MPa, the push force increases to 18095N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 700 mm nominal stroke by up to 40 mm, creating a usable travel window of 660 to 700 mm. It only sets the end position; it does not lock the load without live air pressure.
