Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-40S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 1000mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-40S
The AirTAC SAIJ32X1000-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 1000 mm nominal stroke that can be trimmed back by up to 40 mm, creating a precise 960-1000 mm usable travel window for fine-tuning end positions at commissioning. Delivering 402 N of push force and 345 N of pull force at 0.5 MPa, it suits lighter-duty tasks requiring exact positioning.
This variant features a standard carbon steel rod and a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. Because the 1000 mm stroke reaches the maximum standard limit for this 32 mm bore, it is produced as a made-to-order non-standard length, and the long unsupported travel requires an external guide to prevent rod side-load damage.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-40S Is Used
Long-Stroke Part Ejection
Dial in the exact 960-1000 mm retract position to consistently eject parts of varying widths from a machine bed without repositioning the cylinder mount.
Product Changeover Stops
Quickly adjust the end-stop by up to 40 mm to accommodate new package lengths on a conveyor line during production format changes.
Sensor-Verified Positioning
Leverage the integrated magnet with DMSE solid-state sensors to confirm end-of-stroke arrival at both the fully extended and adjusted retract positions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-40S the Right Cylinder?
Select this 32 mm bore when you need 402 N of push thrust at 0.5 MPa over a very long distance, stepping up to the 40 mm bore yields 628 N if your payload increases. The integrated -40 mm rear adjuster allows you to dial in the exact retract end-stop during machine setup or product changeover without swapping the cylinder or adding external stops. The PT tapered porting and standard carbon steel rod are configured for general industrial air systems.
For a 1000 mm stroke, supporting the load with an external guide rail is essential to prevent rod binding. Remember that the rear adjuster acts only as a travel stop, not a locking device; this plain SAIJ cylinder will not hold its load without live air pressure. For positive load-holding, select an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

- ✓ 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 SAIJ32X1000-40S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
A rear external screw acts as a mechanical stopper, allowing you to shorten the 1000 mm nominal stroke by up to 40 mm, resulting in a 960-1000 mm usable travel window. The adjuster only sets the end position; it does not lock the load without live air pressure.
