Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-50
The AirTAC SAIJ160 Adjustable Cylinder SAIJ160BX155-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 155mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-50
Its 155 mm nominal stroke can be dialed back by up to 50 mm, creating a 105-155 mm usable travel window for precise end-position tuning. This allows you to dial in the exact retract distance during commissioning without swapping out the cylinder or adding external stops.
This unit features a SUS304 stainless steel rod (code B) for superior corrosion resistance and carries a G3/4 PT tapered port. It operates at 30-500 mm/s and relies on a 50 mm air cushion at both ends to decelerate the load. The rear adjuster acts purely as a travel stop, meaning it cannot hold a load without live air pressure.

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 SAIJ160BX155-50 Is Used
Variable End-Stop Configuration
Dial in the 105-155 mm retract distance during machine setup to accommodate different material thicknesses without physically changing the cylinder.
Precision Positioning Stops
Use the rear stopper screw to set exact end-of-stroke limits for large parts, relying on the 50 mm air cushion to smoothly decelerate the 40 mm rod.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-50 the Right Cylinder?
The 50 mm adjustment range is ideal for production lines running mixed product sizes, letting operators change the retract end-stop on the fly instead of re-piping a fixed SAI cylinder. For any load-holding requirements without live air, this standard adjuster will not suffice; you must specify a SAIL pneumatic lock or an external rod lock.
To match this cylinder for an ISO 15552 replacement, verify the 160 mm bore, 155 mm stroke, 50 mm adjustment, G3/4 PT port, and SUS304 rod. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. Although the stroke is under 300 mm, the heavy 40 mm rod and substantial thrust mean you should still ensure rigid external guiding to handle potential side loads.
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 SAIJ160BX155-50 FAQ
The rear adjuster screw allows you to shorten the 155 mm nominal stroke by up to 50 mm, providing a usable travel window of 105 to 155 mm. This stopper only sets the travel end and does not lock the load without continuous air pressure.
