About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-100S
The AirTAC SAIJ32X850-100-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 850mm travel that can be dialed back by up to 100mm, yielding a usable window of 750-850mm for precise end-position tuning at commissioning.
This unit includes a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered ports. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet works directly with AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-100S Is Used
Product Changeover Lines
Dial the travel back by up to 100mm to accommodate different package lengths on a conveyor without changing the cylinder mounting.
Commissioning Fine-Tuning
Use the rear stopper to precisely set the 750-850mm retract end-position during machine setup, avoiding the need for external shims.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-100S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when a machine setup requires variable end-stops or product-size changeovers without physically swapping the cylinder or adding external stops.
Because the 850mm stroke is relatively long for the 32mm rod diameter, an external guide is recommended to prevent excessive side-loading and rod deflection. For an ISO 15552 replacement match, specify the 32mm bore, 850mm stroke, 100mm adjustment, PT port, and the -S magnet. Note that SAIJ uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits 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 SAIJ32BX850-100S FAQ
The nominal stroke is 850mm, but the rear adjuster allows you to shorten the effective travel by up to 100mm, providing an adjustable window of 750-850mm.
No, the rear adjuster is a travel stop, not a lock. The cylinder does not hold its load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series.
