About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-40
The AirTAC SAIJ32X700-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 700 mm nominal stroke by up to 40 mm for a precise 660-700 mm usable travel window. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, utilizing a G1/8 port and a 12 mm rod. This configuration features a SUS420J2 stainless steel rod and PT tapered port threads.
Because the stroke extends to 700 mm on a 32 mm bore, an external guide is recommended to manage side-load risks on the unsupported piston rod. The rear adjuster acts purely as a travel stop for end-position tuning during commissioning or product changeover; it does not lock the load without live air. For load-holding requirements, consider an external rod lock or the SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-40 Is Used
Machine Changeover
Quickly fine-tune the 660-700 mm travel end during product size changes without physically replacing the cylinder or bolting on external stoppers.
Variable End Stops
Ideal for diverter gates on conveyors where the exact extended position needs slight calibration to accommodate different package dimensions.
Long-Stroke Dosing
Provides a 700 mm nominal reach with 40 mm of rear adjustment, allowing precise calibration of the fully extended position for long-throw assembly tasks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-40 the Right Cylinder?
Selecting the SAIJ32X700-40 is ideal when you need variable end-stops without swapping cylinders or adding external stops. If your application requires less force, stepping down is not an option below 32 mm in this line, but if you need more rigidity, a 40 mm bore provides 628 N of push force at 0.5 MPa. Remember that the rear screw and air cushions only decelerate the travel end—they do not hold the load without continuous air pressure. For secure positioning without live air, explore the SAIL or BSAI clamp-lock series.
To match this ISO 15552 cylinder exactly, specify the 32 mm bore, 700 mm stroke, 40 mm adjustment range, PT tapered port thread, SUS420J2 rod material, and no magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The operating speed ranges from 30-800 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 Adjustable Cylinder SAIJ32 SAIJ32AX700-40 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster allows you to shorten the effective stroke by up to 40 mm, creating a 660-700 mm adjustable travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
