Airtac Adjustable Cylinder SAIJ32 SAIJ32BX1000-40S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX1000-40S 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 SAIJ32BX1000-40S
The AirTAC SAIJ32X1000-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 1000 mm nominal stroke to a 960-1000 mm usable window. Delivering a 402 N push force at 0.5 MPa, this unit is built for precise end-position calibration during commissioning. Because the 1000 mm length exceeds the standard 1000 mm maximum for this bore, it is supplied as a non-standard, made-to-order component.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a built-in magnet (-S) compatible with AirTAC CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper acts purely as a travel end-deceleration point, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX1000-40S Is Used
Machine Changeover
Dial in the 960-1000 mm travel window during product size transitions without physically swapping the cylinder or repositioning hard stops.
Long-Stroke Positioning
Use the 40 mm adjustment range to perfectly calibrate the extended end-position on a 1000 mm stroke axis, ensuring precise placement of parts.
Assembly Line Setup
Fine-tune the retract end-stop during initial commissioning to compensate for mechanical tolerances across long-stroke automated machinery.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX1000-40S the Right Cylinder?
Choose this 32 mm bore when your application requires a 402 N push force at 0.5 MPa and you need to dial in the exact end-stop without adding external shims. The adjustable stroke is ideal for product changeovers, whereas a fixed-stroke SAI cylinder requires manual modifications to alter the travel. If your setup demands higher thrust, stepping up to the 40 mm bore yields a 628 N push force at the same pressure.
When ordering, confirm the PT tapered port threads, the SUS304 rod material, and the -S magnet option. Because this is a 1000 mm stroke, the 12 mm rod and M10x1.25 thread will experience significant side-loading if the load is unsupported; an external guide rail is strongly recommended to prevent premature wear. For any load-holding requirements without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is only a stop.

- ✓ 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 SAIJ32BX1000-40S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides a 402 N push force and a 345 N pull force. At 0.7 MPa, the push force increases to 563 N. The operational speed range is 30-800 mm/s.
The rear adjusting screw allows you to shorten the effective stroke by up to 40 mm, creating a 960-1000 mm usable travel window. This stopper only sets the travel end and does not hold the load without live air pressure.
