About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-75S
The AirTAC SAIJ32X700-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 625 to 700 mm window. Delivering 402 N of push force at 0.5 MPa, it is equipped with a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and a PT tapered port thread. The integrated magnet (-S) enables direct mounting of CMSE reed or DMSE electronic solid-state sensors along the dual-side extruded aluminum barrel grooves.
Because the nominal 700 mm stroke is relatively long for a 32 mm bore, the 12 mm rod diameter and M10x1.25 thread mean external guidance is highly recommended to prevent excessive side-loading on the piston. The rear adjuster acts purely as a mechanical stop to set the exact retract end-position during commissioning or product changeover, without needing to swap out the cylinder or bolt on external stops. It does not lock or hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-75S Is Used
Machine Changeover
Dial in the exact retract position from 625 to 700 mm during product size transitions without replacing the cylinder or re-engineering fixed external stops.
Variable End-Stop Positioning
Set precise rejection or sorting distances on a conveyor line by trimming the stroke up to 75 mm to accommodate different package dimensions.
Commissioning Calibration
Fine-tune the end-of-stroke position during initial machine setup to perfectly align tooling, absorbing mechanical tolerances without adding spacer shims.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-75S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke model when your machine setup requires variable end-stops or precise end-position tuning on the fly, offering a clear advantage over a fixed-stroke SAI cylinder. If your application needs greater thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa, but for lighter-duty tasks requiring exact 625 to 700 mm travel, this SKU is ideal. When sourcing an ISO 15552 replacement, ensure you match the 32 mm bore, 700 mm stroke, up to 75 mm adjustment, PT port, and the -S magnet requirement.
For any stroke length of 300 mm or more, side-load management becomes critical; always pair this cylinder with an external linear guide to support the load. Remember that the rear adjuster and the variable air cushions at both ends only decelerate the travel end—they do not function as a brake. If your application requires true load-holding without live air pressure, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder series instead.

- ✓ 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 SAIJ32AX700-75S FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw lets you mechanically shorten the effective travel from the nominal 700 mm down to as little as 625 mm. This creates a 75 mm usable tuning window for setting the exact retract end-position without changing the cylinder's physical mounting.
