About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-50
The AirTAC SAIJ32X450-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 400-450 mm window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This adjustable model omits the FB, CA, CB, and CR mounting options, offering a focused set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories. The rear adjuster acts purely as a mechanical stop to trim the stroke and must not be confused with a locking mechanism, as it cannot hold a 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 SAIJ32BX450-50 Is Used
Product Changeovers
Dial in the 400-450mm travel window on the fly to accommodate slight variations in product sizes without changing the cylinder.
Machine Setup
Fine-tune the retract end-position during initial commissioning to perfect the pickup or placement point of a tooling head.
Variable End Stops
Adjust the stroke dynamically for sorting or diverting tasks on a conveyor line where the physical stop location must shift.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-50 the Right Cylinder?
Choose this 32mm bore when you need precise end-position tuning during machine commissioning or product changeovers, avoiding the need to physically swap cylinders. Because the 450mm stroke is relatively long for a 12mm rod, an external guide is recommended to manage side loads and prevent rod deflection.
For an ISO 15552 replacement, match the 32mm bore, 450mm nominal stroke, 50mm adjustment range, PT ports, and the desired mounting kit. Note that the rear adjustment screw and the variable air cushions only decelerate the load; for true position holding without live air, select an AirTAC SAIL or BSAI series cylinder.

- ✓ 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 SAIJ32BX450-50 FAQ
It can reach up to 82 kgf at its maximum 1.0 MPa pressure.
The rear adjuster acts as a mechanical stop that lets you shorten the 450mm nominal stroke by up to 50mm, creating a usable 400-450mm travel window. It is a travel stop, not a lock, so it cannot hold a load without continuous air pressure.
