About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-30S
The AirTAC SAIJ160X165-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. With a 165 mm nominal stroke and a 30 mm adjustment range, it provides a usable travel window of 135 to 165 mm. This enables precise retraction tuning during commissioning without swapping the unit or adding external stops.
This variant includes a SUS304 stainless steel piston rod (code B) for superior corrosion resistance and ships with a magnet for position sensing. It is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches mounted into the dual-side sensor grooves on the extruded aluminum barrel. The standard PT tapered port threads and adjustable air cushions at both ends ensure reliable sealing and controlled deceleration of heavy loads.

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 SAIJ160BX165-30S Is Used
Variable End-Stop Tuning
Dial in the exact 135 to 165 mm retraction point during machine setup to accommodate varying material thicknesses without replacing hardware.
Product Changeover
Quickly adjust the stroke on automated assembly lines when switching between different product sizes, minimizing downtime between runs.
Sensor-Equipped Positioning
Leverage the built-in magnet and dual sensor grooves to mount CMSE or DMSE switches for precise end-of-stroke confirmation in heavy-duty automation.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-30S the Right Cylinder?
The adjustable stroke is ideal for production lines running multiple product sizes, allowing you to shift the end-stop on the fly. Since the rear adjuster functions strictly as a mechanical stop and the air cushion only handles deceleration, neither will hold the load without live air pressure. For true fail-safe load holding, integrate an external pilot-operated check valve or specify a BSAI clamp-lock cylinder. To match this replacement exactly, verify the 160 mm bore, 165 mm stroke, PT port thread, and the -S magnet option. As an ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders such as SMC or Festo equivalents.
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 SAIJ160BX165-30S FAQ
A rear-mounted adjusting screw acts as a mechanical stop, allowing you to shorten the 165 mm nominal stroke by up to 30 mm, creating a usable travel window of 135 to 165 mm. Note that this adjuster sets the end position and does not lock the load without live air pressure.
