About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-30S
The AirTAC SAIJ32X800-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402 Newtons of push force at 0.5 MPa and features a 12 mm SUS420J2 stainless steel rod. With an 800 mm nominal stroke and a 30 mm adjustment range, you can dial back the effective travel to anywhere within a 770-800 mm window during commissioning.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when fine-tuning machine positions. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports AirTAC CMSE (reed) and DMSE (electronic) solid-state switches for precise position detection.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-30S Is Used
Long-Stroke Conveying
Fine-tune the 770-800 mm retraction point on extended conveyor diverters without physically changing the cylinder length during product changeovers.
Machine Setup Calibration
Dial in the exact end-stop position during initial commissioning using the rear 30 mm adjuster, avoiding the need for external shims or spacer blocks.
Variable End-Stop Positioning
Adjust the effective travel window on the fly for long-stroke assembly presses that handle slightly varying part lengths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX800-30S the Right Cylinder?
Choose this 32 mm bore when you need 402 N of push force at 0.5 MPa with exact end-position tuning over a long 770-800 mm travel window. If your application requires less force, dropping down is not an option in this bore range, but stepping up to a 40 mm bore increases push force to 628 N. The rear adjuster acts purely as a mechanical stop and does not hold the load without live air; for dead-air load holding, consider an AirTAC SAIL or BSAI lock cylinder.
Because this cylinder features an 800 mm stroke, the 12 mm rod requires external guidance to prevent excessive side-loading and premature seal wear. To match this ISO 15552 cylinder exactly, specify the 32 mm bore, 800 mm stroke, 30 mm adjustment, PT tapered port threads, the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), and the -S magnet option.
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 SAIJ32AX800-30S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm. This provides a usable travel window of 770-800 mm. Note that the adjuster only sets the end position; it does not lock or hold the load without continuous air pressure.
At 0.5 MPa operating pressure, the SAIJ32X800-30-S generates 402 Newtons of push force and 345 Newtons of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
