About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX25-10S
The AirTAC SAIJ32X25-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 15 to 25 mm. Designed for fine end-position tuning at commissioning, it allows you to dial back the 25 mm nominal stroke by up to 10 mm without swapping the cylinder or adding external stops. In the compact 32 mm bore class, it delivers a push force of 402 N and a pull force of 345 N at 0.5 MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It is compatible with AirTAC CMSE reed and DMSE electronic solid-state switches fitted into the sensor grooves on both sides of the extruded aluminum barrel. The rear adjuster acts purely as a travel stop to set the retraction end, meaning it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX25-10S Is Used
Micro-Clamp Positioning
Dial in the exact 15 to 25 mm clamping depth on delicate workpieces, preventing deformation during automated machining operations.
Product Changeover
Quickly readjust the retract end-stop by up to 10 mm on packaging lines when switching between slightly different product sizes.
Sensor Actuation Timing
Leverage the integrated magnet and DMSE electronic sensors to confirm exact end positions while fine-tuning the stroke during machine commissioning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX25-10S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires precise mechanical end-stop tuning rather than the fixed stroke of a standard SAI model. If your setup needs less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore increases the 0.5 MPa push force to 628 N. For load-holding without continuous air pressure, this cylinder is insufficient since the adjuster is not a lock; consider an external pilot-operated check valve or the SAIL lock variant instead.
To match this exact ISO 15552 interchangeable replacement, specify a 32 mm bore, 25 mm stroke, 10 mm adjustment range, PT tapered port threads, and the -S magnet option. Because the stroke is only 25 mm, side-load risks are minimal, but always ensure the M10x1.25 rod thread is properly aligned to prevent binding. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

- ✓ 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 SAIJ32BX25-10S FAQ
At a standard operating pressure of 0.5 MPa, this 32 mm bore cylinder provides a push force of 402 N and a pull force of 345 N. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a usable travel window of 15 to 25 mm. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
