About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-20S
The AirTAC SAIJ160X155-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the nominal 155mm travel to fine-tune the retract end position. This creates a 135-155mm usable travel window for precise machine setup without needing external stops.
As a true profile cylinder featuring an extruded aluminum barrel with sensor grooves on both sides, it supports AirTAC CMSE reed and DMSE electronic solid-state sensors. The integrated PT tapered ports and 50mm air cushions at both ends manage deceleration, while the rear stopper acts purely as a travel end adjuster rather than a load-holding lock.

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 SAIJ160BX155-20S Is Used
Variable End-Stop Tuning
Dial in the exact 135-155mm retract position during machine commissioning to accommodate varying product sizes without adding physical shims.
Automated Changeover
Quickly adjust the effective stroke on product lines to handle different material thicknesses, reducing setup downtime between production runs.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-20S the Right Cylinder?
The adjustable 135-155mm travel window is ideal for product changeovers where exact end-position tuning is necessary without swapping cylinders. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ rear adjuster only sets the travel end and does not lock the load.
When replacing an ISO 15552 cylinder, match the 160mm bore, 155mm stroke, 20mm adjustment range, PT G3/4 ports, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments, deliberately omitting FB, CA, CB, and CR styles. Because the 155mm stroke is relatively short for this large bore, side-load risks are minimal, but external guides are still recommended for heavy unsupported 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 SAIJ160BX155-20S FAQ
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the effective travel by up to 20mm from the nominal 155mm stroke, creating a usable travel window of 135-155mm for fine-tuning the end position.
