About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-50
The AirTAC SAIJ160X170-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers substantial thrust, generating 10053N of pull force at 0.5 MPa and pushing 14074N at 0.7 MPa. By turning the rear stopper screw, you can fine-tune the effective travel down from the 170mm nominal stroke, yielding a 120-170mm usable positioning window for exact product changeovers.
This heavy-duty actuator features a SUS304 stainless steel piston rod for superior corrosion resistance and uses PT tapered port threads. It includes variable air cushions at both ends to absorb kinetic energy, operating at speeds of 30-500mm/s. The extruded aluminum barrel integrates sensor grooves on both sides for flexible mounting of CMSE reed or DMSE solid-state sensors.

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 SAIJ160BX170-50 Is Used
Heavy Press Tuning
Dial in the exact 120-170mm travel window during setup to accommodate varying material thicknesses in large pneumatic presses.
Product Changeover Stops
Adjust the retract end-position on the fly when switching a conveyor line to handle different package dimensions.
Assembly Station Setup
Fine-tune the end-of-stroke position without swapping the entire cylinder or adding bulky external mechanical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-50 the Right Cylinder?
Choose this 160mm bore actuator when a fixed-stroke SAI cylinder cannot accommodate slight mechanical variations during machine commissioning. If you need less force, stepping down to a 125mm bore yields 5734N of pull force at 0.5 MPa; stepping up to a 200mm bore provides 15080N. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure—use a SAIL or BSAI lock cylinder for fail-safe load holding. This unit is dimensionally interchangeable per ISO 15552, requiring a 160mm bore, 170mm stroke, PT G3/4 ports, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
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 SAIJ160BX170-50 FAQ
At 0.7 MPa, the push force increases to 14074N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 170mm nominal stroke by up to 50mm, providing a usable travel window of 120-170mm for precise end-position tuning.
