About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX950-20
The AirTAC SAIJ32X950-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides, and this specific configuration features a SUS420J2 stainless steel rod and PT tapered ports.
Because the 950 mm stroke approaches the 1000 mm maximum standard stroke limit for this 32 mm bore, the built-in rear stopper is critical for fine-tuning the end position without adding external physical stops. The 12 mm rod and M10x1.25 thread handle moderate loads, but at this extended length, an external guide is highly recommended to prevent side-load damage. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX950-20 Is Used
Extended Transfer Lines
Provides 930-950 mm of adjustable travel for long-bed conveyor indexing, letting operators fine-tune the retracted end position to match varying product lengths.
Machine Commissioning
The 20 mm rear stopper allows precise end-position tuning during equipment setup, eliminating the need to swap cylinders or bolt on external physical stops.
Product Changeover
Ideal for packaging lines running multiple package sizes, where dialing back the stroke by up to 20 mm accommodates a new format without changing the actuator.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX950-20 the Right Cylinder?
If your project requires less travel or a shorter footprint, stepping down to a shorter stroke is ideal, but if you need higher force, the 40 mm bore offers 628N at 0.5 MPa. The adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for machine setup or product changeovers.
For an exact ISO 15552 replacement match, verify the 32 mm bore, 950 mm nominal stroke, 20 mm adjustment range, PT port thread, and the SUS420J2 rod material. Note that SAIJ uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Because the stroke is 950 mm, you must use an external guide to support the load, as the rear adjuster and air cushions only decelerate the travel and do not lock or hold the load without live air pressure.
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 SAIJ32AX950-20 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 20 mm, providing a usable travel window of 930 to 950 mm. It only sets the travel end and does not lock or hold the load without live air pressure.
At 0.7 MPa, the push force increases to 563N.
