About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-100
The AirTAC SAIJ32X290-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the retract position. With a nominal 290 mm stroke and a 100 mm adjustment range, it provides a highly flexible 190-290 mm usable travel window for dialing in exact end stops without adding external physical stops.
Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit utilizes a SUS304 stainless steel rod for superior corrosion resistance. It operates at speeds of 30-800 mm/s, uses a PT G1/8 tapered port, and includes variable air cushions at both ends to manage deceleration across its extended travel.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-100 Is Used
Product Changeovers
Quickly adapt the 190-290 mm travel window on packaging lines when switching between different container sizes without swapping out the entire actuator.
End-Stop Calibration
Fine-tune the retract position during machine setup to achieve exact placement, relying on the rear screw to set the boundary rather than external hard stops.
Variable Diverter Stroke
Adjust the pusher depth on a sorting conveyor on the fly, allowing operators to dial in the exact 190 to 290 mm extension needed for various product widths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-100 the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires precise position tuning during commissioning or frequent product changeovers, stepping up to a 40 mm bore (628 N push at 0.5 MPa) is only necessary if the load demands higher thrust. Because the stroke extends to 290 mm, an external guide is recommended to prevent excessive side-loading on the SUS304 piston rod. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure; for true load-holding without continuous air, consider an AirTAC SAIL or BSAI variant.
As a dimensionally interchangeable ISO 15552 cylinder, this model matches standard mounting footprints using a reduced SAIJ accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. To replicate this exact configuration, specify the 32 mm bore, 290 mm stroke, 100 mm adjustment, PT port thread, SUS304 rod, and no magnet.

- ✓ 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 SAIJ32BX290-100 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If your application requires more thrust, stepping up to a 40 mm bore yields 628 N of push force at the same pressure.
The rear adjuster screw allows you to mechanically shorten the effective stroke by up to 100 mm from the nominal 290 mm, creating a 190-290 mm travel window. This stopper only sets the end position and deceleration point; it does not lock the load without continuous air pressure.
