About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-40
The AirTAC SAIJ160X155-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 115 to 155 mm, allowing you to dial back the nominal stroke by up to 40 mm during commissioning. Operating at 0.9 MPa, it delivers a robust pushing force of 18095N, making it suitable for heavy-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports a speed range of 30-500 mm/s and utilizes adjustable air cushions at both ends to manage deceleration smoothly.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|

| 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 SAIJ160BX155-40 Is Used
Heavy-Duty Positioning
Fine-tune the 115-155 mm travel window to precisely set heavy machinery stops without adding external mechanical spacers.
Product Changeover
Quickly adjust the end-of-stroke position on packaging lines when handling different product sizes, reducing setup downtime.
Machine Setup
Dial in the exact retract position during initial commissioning to achieve perfect alignment without swapping cylinders.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-40 the Right Cylinder?
The adjustable stroke is ideal for applications requiring exact end-position tuning during machine setup or product changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. Remember that the rear adjuster functions only as a travel stop, not a lock; the cylinder will not hold its load without live air pressure. For secure load-holding, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 155 mm stroke, 40 mm adjustment range, PT port threads, and the required mounting accessories. The SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations, omitting FB, CA, CB, and CR options. Although the 40 mm rod diameter handles substantial side loads, always use an external guide for long unsupported strokes.
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 SAIJ160BX155-40 FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates a pushing force of 18095N and a pulling force of 9425N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 155 mm nominal stroke down to 115 mm. This allows fine-tuning of the end position at commissioning, but it does not lock or hold the load without continuous air pressure.
