About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-30S
The AirTAC SAIJ32X80-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 80mm nominal stroke by up to 30mm to achieve a precise 50-80mm usable travel window. Delivering 402N of push force and 345N of pull force at 0.5MPa, it suits light-duty positioning tasks. The integrated -S magnet enables position sensing via CMSE reed or DMSE electronic switches mounted in the dual-side sensor grooves.
This variant features a SUS304 stainless steel rod (option B) for superior corrosion resistance, paired with PT tapered port threads (G1/8) for a tight pneumatic seal. The rear adjustment screw acts purely as a mechanical stop to set the retract end-position during commissioning; it does not lock the load, meaning live air pressure is required to hold position.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-30S Is Used
Machine Changeover
Dial in the exact retract distance from 50 to 80mm when switching product sizes on a packaging line, eliminating the need to physically swap out the cylinder.
Sensor Setup
Leverage the internal magnet with DMSE solid-state sensors to confirm the adjusted end-position, ensuring repeatable signaling even if the stroke is dialed back.
Corrosive Environments
Rely on the SUS304 stainless steel rod for light-duty testing fixtures or washdown applications where standard carbon steel rods would pit or degrade.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-30S the Right Cylinder?
Choose this 32mm bore model when your application requires fine-tuning the end-of-stroke at machine setup without swapping cylinders or adding bulky external stops. If your changeover demands less force, stepping down is not an option in the ISO 15552 range, but if you need higher clamping power, stepping up to a 40mm bore yields 628N of push force at 0.5MPa. Because this cylinder features an 80mm stroke, side-load risks are minimal, but always ensure the M10x1.25 rod thread is aligned with your load to prevent binding.
For a true drop-in ISO 15552 replacement, verify your footprint matches the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces (the SAIJ series omits FB, CA, CB, and CR brackets). Remember that the rear adjuster and air cushions only decelerate the travel end; if you need to hold a load vertically without continuous air pressure, use an external pilot-operated check valve or select the AirTAC SAIL or BSAI locking cylinder series instead.

- ✓ 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 SAIJ32BX80-30S FAQ
The rear adjuster is a mechanical stop that lets you shorten the effective travel by up to 30mm, creating a usable 50-80mm stroke window. It allows fine-tuning the end position at commissioning without changing the cylinder, but it does not lock the load without live air pressure.
At 0.5MPa operating pressure, it provides 402N of push force and 345N of pull force. It operates at speeds between 30 and 800mm/s and features variable air cushions at both ends to manage deceleration.
