About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-75S
The AirTAC SAIJ160X170-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 170 mm travel by up to 75 mm. This creates a highly versatile 95-170 mm usable stroke window, perfect for fine-tuning end positions during machine commissioning without swapping hardware.
This unit features a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered ports match the G3/8 standard for this bore. It operates at speeds of 30-500 mm/s and relies on adjustable air cushions at both ends to decelerate the load smoothly.

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 SAIJ160BX170-75S Is Used
Heavy Press Tuning
Dial in the exact 95-170 mm end position for heavy pressing tasks, ensuring precise force application without needing to swap out the entire cylinder.
Product Line Changeover
Quickly adapt machinery to new product sizes by adjusting the retract stroke up to 75 mm, drastically reducing setup times between production runs.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-75S the Right Cylinder?
The 75 mm adjustment range is ideal for product changeovers requiring variable end-stops, eliminating the need to bolt on external stops or replace a fixed-stroke SAI cylinder. For stroke lengths of 300 mm or more, an external guide is recommended to handle side loads, though this 170 mm stroke is well within standard limits. Remember that the rear adjuster is a travel stop, not a lock; this SAIJ model cannot hold a load without live air, so for true position holding, consider an SAIL or BSAI cylinder. As a dimensionally interchangeable ISO 15552 cylinder, ensure your replacement matches the 160 mm bore, 170 mm stroke, 75 mm adjust, G3/8 PT ports, and -S magnet.
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 SAIJ160BX170-75S FAQ
At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 75 mm from the 170 mm nominal stroke, creating a 95-170 mm usable window. It only sets the travel end and does not lock the load without live air pressure.
