About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-30
The AirTAC SAIJ160X170-30 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, enabling you to dial back the nominal 170 mm stroke by up to 30 mm. This yields a precise 140-170 mm usable travel window, allowing exact end-position tuning during commissioning without swapping out the barrel or adding external stops.
Because the rear adjuster functions purely as a travel stop and works in tandem with the adjustable air cushions, it decelerates the piston but does not hold the load without live air pressure. For fail-safe load holding, you would need a related SAIL pneumatic lock or an external pilot-operated check valve. The extruded aluminum body includes sensor grooves on both sides for adding CMSE reed or DMSE electronic switches if needed.

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 SAIJ160BX170-30 Is Used
Press Tonnage Setup
Fine-tune the 140-170 mm stroke window to set exact pressing depth for different material thicknesses during machine changeover.
Variable End-Stop Positioning
Use the rear 30 mm adjuster to dial in the exact retraction point without disassembling the cylinder or mounting external physical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-30 the Right Cylinder?
Selecting this 160 mm bore over the neighboring 125 mm size gives you a significant thrust jump, moving from 8590 N to 14074 N at 0.7 MPa. The adjustable-stroke design is chosen over a fixed SAI cylinder when a machine requires variable end-stops to accommodate product changeovers or fine-tuning at setup. It supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Even though the stroke is under 300 mm, the substantial 40 mm rod diameter and M36x2 thread handle high side loads well, though an external guide remains best practice for heavy masses.
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 SAIJ160BX170-30 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 170 mm stroke by up to 30 mm, providing a usable travel window of 140 to 170 mm for fine-tuning at commissioning.
