About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-30S
The AirTAC SAIJ32X450-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 450 mm travel by up to 30 mm. This creates a precise 420-450 mm usable window for fine-tuning end positions at commissioning without adding external stops. It features a SUS420J2 stainless steel rod and a built-in magnet for position sensing.
Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit uses PT tapered ports and offers adjustable air cushions at both ends. The SAIJ series utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. The extruded aluminum barrel includes sensor grooves on both sides, fully compatible with AirTAC CMSE reed and DMSE electronic switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-30S Is Used
Machine Changeover
Dial in the 420-450 mm travel window during product size transitions to set new end positions rapidly without swapping cylinders.
Component Seating
Fine-tune the rear stopper to perfectly seat delicate parts at the end of the stroke, absorbing impact via the adjustable air cushion.
Tooling Setup
Establish exact end-of-travel limits during initial machine commissioning, tweaking the 30 mm adjustment range to perfect the process.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-30S the Right Cylinder?
Choose this specific adjustable model when your machine setup requires variable end stops or frequent product changeovers, avoiding the need to physically swap a fixed-stroke SAI cylinder. If your application demands greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Remember that the rear adjuster acts only as a travel stop to set deceleration, not as a lock; this cylinder will not hold a load without live air. For position holding, consider the SAIL or BSAI series.
Because this unit features a 450 mm stroke, the 12 mm rod diameter requires external guiding to prevent excessive side-loading on the seals. To match this exact ISO 15552 replacement, configure the 32 mm bore, 450 mm stroke, 30 mm adjustment, PT port thread, 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 SAIJ32AX450-30S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at its maximum 0.9 MPa operating pressure.
The rear adjuster allows you to shorten the effective travel from the 450 mm nominal stroke by up to 30 mm, creating a 420-450 mm usable window. This stopper sets the travel end and deceleration, but it does not lock or hold the load without continuous air pressure.
