About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-40
The AirTAC SAIJ160X700-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing with 18095N at 0.9 MPa, making it suited for heavy-duty industrial positioning. The built-in adjustment mechanism allows you to fine-tune the travel window from 660 to 700 mm directly at the machine without swapping out the unit.
This specific SKU is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts only as a travel stop to decelerate the piston; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-40 Is Used
Heavy Press Positioning
Provides 18095N of thrust at 0.9 MPa for heavy pressing operations, with a 660-700 mm adjustable window to dial in the exact compression distance.
Product Line Changeover
Quickly adapt machinery to new part sizes by turning the rear stopper up to 40 mm, avoiding the need to physically swap out long-stroke cylinders.
Large Material Handling
Shifts substantial payloads across a 700 mm travel distance, relying on the robust 40 mm stainless steel rod and external guides for stable motion.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-40 the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore (providing 4523N push at 0.9 MPa) cannot generate enough force for heavy loads. The 40 mm adjustment range is ideal for product changeovers, letting you shift the end-stop by up to 40 mm during commissioning rather than installing a fixed-stroke SAI cylinder. Because this unit lacks a magnet, you cannot mount CMSE or DMSE sensors for position detection.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 700 mm nominal stroke, 40 mm adjustment, PT port thread, and SUS304 rod material. Since the 700 mm stroke is long, the 40 mm diameter rod needs external guidance to prevent excessive side-load wear. For applications requiring the load to be held without continuous air pressure, select a SAIL or BSAI series cylinder instead of this standard SAIJ.
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 SAIJ160BX700-40 FAQ
The rear adjuster screw lets you shorten the effective travel by up to 40 mm, creating a 660 to 700 mm usable window. It acts as a mechanical stop to set the end position precisely during setup.
At 0.9 MPa operating pressure, the push force is 18095N and the pull force is 9425N. It can achieve a maximum force of 2050 kgf at 1.0 MPa.
