About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-50S
The AirTAC SAIJ160X165-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 165 mm nominal stroke that can be dialed back by up to 50 mm, yielding a usable travel window of 115 to 165 mm. This specific adjustment range is ideal for heavy-duty production lines needing rapid product-size changeovers without physically swapping the actuator.
Built as a true extruded aluminum profile cylinder, it features a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The integrated magnet enables position sensing via AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts strictly as a travel stop for end-position tuning, not a lock, meaning the load is only held by live air pressure during operation.

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 SAIJ160BX165-50S Is Used
Heavy Product Changeover
Dial in the exact retract distance from 165 mm down to 115 mm when switching heavy product sizes on a packaging line, avoiding mechanical teardown.
Commissioning End-Stop Tuning
Fine-tune the end position during initial machine setup to absorb mechanical tolerances, using the rear screw rather than repositioning hard stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX165-50S the Right Cylinder?
Choose the SAIJ160X165-50-S when your machinery requires fine-tuning the retract end-position at commissioning without adding external stops. If your application requires the cylinder to hold a load safely without continuous live air pressure, this standard adjuster will not function as a brake; you must step up to an SAIL air-released lock or a BSAI clamp-lock cylinder instead.
To match this ISO 15552 interchangeable footprint for a direct replacement, specify the 160 mm bore, 165 mm stroke, 50 mm adjustment range, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting options, and the -S magnet. Because the 165 mm stroke is relatively short for this large bore, side-loading is minimal, but long unsupported strokes should always use an external guide to protect the 40 mm rod and M36x2 thread.
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 SAIJ160BX165-50S FAQ
The rear adjuster acts as an external stop that trims the effective travel. For this model, the 165 mm stroke can be shortened by up to 50 mm, giving an adjustable travel window of 115 to 165 mm. It only sets the end position; it does not lock the load without live air.
At 0.9 MPa, the push force increases to 18095 N.
