About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-30S
Its built-in adjustment screw provides a usable travel window of 260-290mm, allowing you to trim the effective stroke by up to 30mm without swapping the cylinder. This is ideal for fine-tuning end positions during commissioning or product changeovers.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and carries PT tapered port threads sized G3/4. The extruded aluminum barrel includes sensor grooves on both sides, and the included magnet (-S) supports position detection using AirTAC CMSE reed or DMSE electronic solid-state switches. With a 290mm stroke, the robust 40mm rod diameter helps manage side loads, though an external guide is still recommended for heavy unsupported masses.

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 SAIJ160BX290-30S Is Used
Product Size Changeover
Dial in the 260-290mm travel window during format changes on a packaging line, avoiding the need to physically swap out cylinders for different carton depths.
Heavy Press Tuning
Precisely set the retraction end-stop for a high-force pressing or clamping operation, using the 10053N pull force at 0.5 MPa to secure components.
Machine Commissioning
Fine-tune the final resting position of heavy actuators during initial machine setup, compensating for mechanical tolerances without adding external stopper blocks.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-30S the Right Cylinder?
The adjustable 260-290mm window eliminates the need to bolt on external stops or machine a new fixed-length SAI cylinder when product sizes change. Because the stroke is 290mm, ensure adequate external guiding to handle side loads over the extended travel.
For a direct ISO 15552 interchangeable replacement, match the 160mm bore, 290mm stroke, 30mm adjustment code, PT G3/4 ports, and the -S magnet requirement. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI series cylinder instead. Mounting options for this series include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX290-30S FAQ
The rear adjuster screw allows you to shorten the nominal 290mm stroke by up to 30mm, creating a usable travel window of 260-290mm. The adjuster acts as a mechanical stop to fine-tune the retract position and does not lock the load without continuous air pressure.
