About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-100
The AirTAC SAIJ32X190-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel between 90 and 190 mm. Using the nominal 190 mm stroke, the external stopper can be dialed back by up to 100 mm, providing immense flexibility during machine commissioning or product changeovers without swapping the physical cylinder. In the 32 mm bore class, it generates 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant uses a SUS304 stainless steel piston rod (option B) for superior corrosion resistance, paired with PT tapered port threads on its G1/8 supply ports. The extruded aluminum barrel includes sensor grooves on both sides for mounting standard switches. The rear adjuster acts purely as a mechanical stop to set the end position, working alongside the 27 mm variable air cushions at both ends to decelerate the load.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-100 Is Used
Product Changeovers
Dial in the exact end-position from 90 to 190 mm on packaging lines when switching to a different product size, eliminating the need to physically swap cylinders or add external shims.
Machine Setup
Fine-tune the retract stroke during initial commissioning to perfectly time the 402 N push force against a workpiece without re-machining hard stops.
Variable End Stops
Provide an adjustable mechanical stop for light-duty testing rigs, allowing operators to quickly test multiple stroke lengths within the 100 mm adjustment window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-100 the Right Cylinder?
Choose this 32 mm bore model when your application requires a wide variable end-stop window within a compact ISO 15552 footprint. If your setup demands higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa, but increases the physical envelope. The SAIJ32X190-100 is selected specifically when you need to trim the stroke during commissioning rather than relying on a fixed-stroke SAI cylinder. To match this cylinder for an ISO 15552 replacement, verify the 32 mm bore, 190 mm stroke, 100 mm adjustment range, PT port thread, and the absence of a magnet (-S not specified). Because the stroke is under 300 mm, side-load concerns are minimal, but an external guide is still recommended for heavy lateral loads.
Remember that the rear adjuster is a travel stop, not a locking mechanism. It will not hold a load in place without live air pressure. If your application requires true fail-safe load holding, consider the SAIL air-released lock or BSAI clamp-lock cylinder series instead.

- ✓ 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 SAIJ32BX190-100 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 the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 190 mm stroke by up to 100 mm, creating a usable travel window of 90 to 190 mm. It sets the end position but does not lock the load without live air pressure.
