About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-30S
The AirTAC SAIJ160X145-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 145 mm nominal travel by up to 30 mm for a precise 115-145 mm usable window. This fine-tuning capability is ideal for product changeovers, letting you set exact end positions at commissioning without swapping hardware or adding external stops. It delivers formidable force, pushing with 14074 N and pulling with 9425 N at 0.7 MPa.
This bore uses a robust 40 mm piston rod with an M36x2 thread, paired with 50 mm of adjustable pneumatic cushioning at both ends to manage heavy impact loads. The barrel is extruded aluminum with sensor grooves on both sides, and because this SKU includes the -S magnet, it interfaces directly with AirTAC CMSE reed and DMSE electronic solid-state switches. The rod is crafted from SUS304 stainless steel for superior corrosion resistance, and ports are PT tapered.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 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 SAIJ160 Adjustable Cylinder SAIJ160BX145-30S Is Used
Heavy Press Tuning
Dial in the exact 115-145 mm retraction depth during heavy press commissioning without installing external mechanical stops.
Product Changeover
Quickly adapt the end-of-stroke position on a conveyor diverter when switching to a new package size.
Assembly Station Setup
Fine-tune the clamping travel window on heavy assembly lines to accommodate varying part dimensions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX145-30S the Right Cylinder?
An adjustable stroke is selected over a fixed SAI cylinder when a machine requires variable end-stops or precise retraction limits during setup. Remember that the rear adjuster is a travel stop, not a lock; it cannot hold a load without live air pressure. For true fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series.
To replace an ISO 15552 cylinder, match the 160 mm bore, 145 mm stroke, 30 mm adjustment, PT G3/4 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting the FB, CA, CB, and CR brackets found on other variants. Because the 40 mm rod and M36x2 thread handle high side loads, this cylinder is well-suited for rigid assemblies, though any long unsupported stroke still requires an external guide.
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 SAIJ160 Adjustable Cylinder SAIJ160BX145-30S FAQ
At its maximum 1.0 MPa pressure, it reaches 2050 kgf.
The rear adjuster screw allows you to shorten the 145 mm nominal stroke by up to 30 mm, creating a usable travel window of 115 to 145 mm. It acts as a mechanical stop to fine-tune end positions, but it is not a lock and requires live air to maintain position.
