About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-10
The AirTAC SAIJ32X850-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402N of push force at 0.5MPa and provides a usable travel window of 840 to 850mm, letting you dial back the nominal 850mm stroke by up to 10mm during commissioning without adding external stops.
This specific SKU is configured with a SUS304 stainless steel rod for corrosion resistance and utilizes PT tapered port threads. Because the 850mm stroke is substantial for a 32mm bore, the 12mm rod diameter requires external guide support to prevent deflection and manage side loads over such a long unsupported distance.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-10 Is Used
Long-Travel Conveyor Positioning
Fine-tunes the extended end-stop by up to 10mm on 850mm travel axes to align pushers precisely with varying product sizes on a conveyor line.
Machine Commissioning
Eliminates the need to swap cylinders or add physical shims during initial setup, allowing operators to dial in the exact 840-850mm travel window on-site.
Stainless Rod Handling
Leverages the SUS304 rod material for light material transfer in environments where moisture or minor corrosion is a concern over long stroke distances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-10 the Right Cylinder?
Choose this 32mm bore model when you need precise end-position tuning on a long-stroke setup; if your application requires less force, stepping down is not an option in the SAIJ range, but stepping up to a 40mm bore increases push force to 628N at 0.5MPa. An adjustable stroke is selected over a fixed SAI cylinder when machine setups require variable end-stops or fine-tuning during product changeovers.
For ISO 15552 replacement matching, verify the 32mm bore, 850mm stroke, 10mm adjustment, PT G1/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for position holding, consider an SAIL or BSAI cylinder. Furthermore, strokes of 300mm or more demand external guiding to protect the piston rod from side-load damage.
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 SAIJ32BX850-10 FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can achieve a maximum push force of 724N at 0.9MPa.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective travel from 850mm down to 840mm. This adjuster only sets the travel end and does not lock the load without live air pressure.
