About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-30S
The AirTAC SAIJ32X850-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down by up to 30 mm, creating a precise 820-850 mm usable window. Using a 32 mm bore, it provides 563 N of push force and 345 N of pull force at 0.5 MPa. The integrated -S magnet supports position sensing with AirTAC CMSE reed or DMSE solid-state switches.
This variant is equipped with a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It uses a 12 mm rod with an M10x1.25 thread, and the adjustable rear stopper acts purely as a travel end-deceleration mechanism, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-30S Is Used
Product Changeover Tuning
Dial in the 820-850 mm travel window during line changeovers to accommodate slightly different package lengths without physically replacing the actuator.
Long-Stroke Assembly Press
Provides 563 N of push force at 0.7 MPa for pressing components, with the rear screw allowing precise calibration of the final end-position.
Variable End-Stop Diverter
Acts as a diverter on a conveyor where the exact stopping position of 32 mm bore parts must be adjusted on the fly for different product sizes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-30S the Right Cylinder?
Choose this 32 mm bore model when your application requires 563 N of push force at 0.7 MPa and demands exact end-position tuning during commissioning without swapping out the cylinder. The rear adjuster allows you to dial in the 850 mm stroke within an 820-850 mm window to accommodate product changeovers. If your setup requires less force, stepping down is an option, but if you need significantly higher thrust, consider a larger bore. For load-holding without live air pressure, this cylinder is insufficient since the adjuster is only a stop; you would need to look at the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 850 mm stroke, 30 mm adjustment, PT port threads, and the -S magnet. Because the stroke is 850 mm, the extended 12 mm rod is highly susceptible to side-loading; an external guide rail is strongly recommended to prevent premature seal wear and binding. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

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 SAIJ32BX850-30S FAQ
At 0.7 MPa operating pressure, this 32 mm bore cylinder generates 563 N of push force and 483 N of pull force. The maximum operating speed is 800 mm/s.
The rear adjuster screw lets you shorten the 850 mm nominal stroke by up to 30 mm, providing an effective travel range of 820 to 850 mm. This stopper only sets the travel end and does not lock or hold the load without continuous air pressure.
