About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-50S
The AirTAC SAIJ32X700-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 650 to 700 mm, allowing you to dial back the end-of-stroke position by up to 50 mm during commissioning. In the 32 mm bore class, it delivers 563 N of push force and 345 N of pull force at 0.7 MPa. This variant includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and a built-in magnet for position sensing.
The extruded aluminum barrel incorporates sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position without adding external stops. It does not lock or hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-50S Is Used
Product Changeover Setup
Dial in the exact retract distance within the 650-700 mm window during format changes without replacing the cylinder or adding external mechanical stops.
Variable End-Stop Diverter
Fine-tune the stroke end position on the fly to handle varying package sizes on a moving conveyor line, ensuring precise routing.
Machine Commissioning
Trim the travel back by up to 50 mm during initial machine setup to perfectly synchronize tooling positions without machining new mountings.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-50S the Right Cylinder?
Choose this 32 mm bore model when your application requires 563 N push force at 0.7 MPa and a highly variable end-stop within a 650 to 700 mm range. If you need less force, there is no smaller standard ISO 15552 bore in this range, but stepping up to a 40 mm bore yields 879 N push force. The adjustable rear screw is ideal for product changeovers, letting you fine-tune travel without swapping the cylinder. For load-holding without live air, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead of relying on the SAIJ adjuster.
Because the 700 mm stroke is long relative to the 12 mm rod diameter, it is highly susceptible to side-loading and buckling. Always use an external guide rail to support the load and prevent rod damage. This SKU specifies PT tapered port threads and includes the -S magnet for use with CMSE and DMSE sensors.
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 SAIJ32BX700-50S FAQ
At 0.7 MPa operating pressure, this 32 mm bore double-acting cylinder provides 563 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the effective travel from the 700 mm nominal stroke down to 650 mm. This mechanical stopper only sets the end position; it does not hold the load without live air pressure.
