About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-100
The AirTAC SAIJ32X190-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the effective travel back by up to 100 mm. This creates a highly flexible 90-190 mm usable stroke window, letting you dial in the exact retract position during commissioning without swapping out the physical unit. It delivers 402 N of push force at 0.5 MPa and utilizes a SUS420J2 stainless steel rod for enhanced durability against moisture.
Equipped with a 12 mm carbon-steel-derived piston rod and a PT G1/8 tapered port, this 32 mm bore actuator operates efficiently at speeds between 30 and 800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for easy switch mounting, though this specific configuration ships without a magnet. The rear stopper screw acts purely as a travel end-deceleration point and does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-100 Is Used
Product Changeover
Quickly adapt the retract distance on packaging lines when switching between different product sizes, using the 100 mm adjustment range to avoid physically replacing the actuator.
Commissioning Calibration
Fine-tune the end-of-stroke position during initial machine setup to achieve precise mechanical alignment without adding bulky external stopper blocks.
Variable End-Stop Assembly
Provide a customizable 90-190 mm travel window on automated assembly stations where multiple parts are tested at slightly different distances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-100 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke model when your machine setup requires variable end-stops or frequent product-size changeovers, avoiding the need to maintain a large inventory of fixed-stroke SAI cylinders. If your application requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa; conversely, dropping to a smaller bore is not standard below 32 mm in this series.
Because the nominal stroke is 190 mm, external side-load guides are recommended if the load is heavy or unsupported. To match this exact replacement, specify: 32 mm bore, 190 mm stroke, 100 mm adjustment, PT G1/8 port, SUS420J2 rod material, and no magnet. For applications requiring the cylinder to hold its position without continuous air pressure, note that this rear adjuster is strictly a stop, not a lock; you should explore an AirTAC SAIL or BSAI series cylinder instead.
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 SAIJ32AX190-100 FAQ
At a standard operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If the pressure is increased to 0.7 MPa, the push force rises to 563 N.
The rear adjuster screw allows you to shorten the 190 mm nominal stroke by up to 100 mm, creating a usable travel window of 90 to 190 mm. The adjuster acts as a mechanical stop to set the end position and is not a locking mechanism.
