About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-20
The AirTAC SAIJ32X550-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to 530 mm from its 550 mm nominal length. This unit utilizes a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads.
Because the adjuster acts purely as a mechanical stop, it sets the retract end position without holding the load pneumatically. For applications requiring position holding without live air pressure, an external rod lock or a related SAIL pneumatic locking cylinder is necessary. This model supports a speed range of 30-800 mm/s and includes adjustable air cushions at both ends to manage impact deceleration.

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 SAIJ32BX550-20 Is Used
Machine Setup Calibration
Dial in the exact retract position within the 530-550 mm window during initial commissioning without swapping out the entire actuator.
Product Size Changeovers
Quickly adjust the end-stop by up to 20 mm on packaging lines to accommodate varying product lengths on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX550-20 the Right Cylinder?
The adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for product changeovers, allowing up to 20 mm of trim without adding external stops. To replace an ISO 15552 cylinder, match the 32 mm bore, 550 mm stroke, PT port thread, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting interface.
With a 550 mm stroke, the 12 mm piston rod requires external guidance to prevent excessive side-loading and premature seal wear. Note that this SKU does not include a magnet; if sensor feedback is needed, select the -S option to enable CMSE reed or DMSE electronic switches.

- ✓ 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 SAIJ32BX550-20 FAQ
The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 550 mm down to 530 mm. It only sets the travel end and does not lock the load without continuous air pressure.
