About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-100
The AirTAC SAIJ32X850-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402N of push force and 345N of pull force at 0.5 MPa, operating at speeds between 30 and 800 mm/s. This specific model uses a PT tapered G1/8 port and a SUS304 stainless steel rod (code B) for enhanced corrosion resistance.
Equipped with a 100mm adjustment mechanism, this SKU allows you to trim the nominal 850mm stroke back, providing a usable travel window of 750 to 850mm. This built-in rear stopper lets you fine-tune end positions at commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE and DMSE switches, though a magnet (-S) is not specified for this configuration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-100 Is Used
Variable End-Stop Machining
Dial in the exact 750-850mm clamping distance during machine setup without swapping out the entire cylinder body.
Product Changeover Lines
Quickly adjust the retract position by up to 100mm to accommodate different product lengths on the same conveyor setup.
Commissioning Fine-Tuning
Use the rear stopper screw to precisely tune the end-of-stroke position during initial commissioning, avoiding mechanical dead stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-100 the Right Cylinder?
Choose this 32mm bore when your application requires 402N of push force at 0.5 MPa and a variable end-stop between 750 and 850mm. If your setup demands higher thrust, stepping up to the 40mm bore yields 628N of push force. The rear adjuster on this SAIJ acts purely as a travel stop to set deceleration, meaning it will not hold a load without live air pressure; for true load-holding, consider an AirTAC SAIL or BSAI cylinder.
Because the nominal stroke is 850mm, the 12mm rod requires external guidance to prevent excessive side-load wear. This cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
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 SAIJ32BX850-100 FAQ
At an operating pressure of 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 100mm. This creates a usable travel window of 750 to 850mm, allowing you to fine-tune the end position without replacing the cylinder.
