About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-30S
It features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. With a nominal 135mm stroke and a 30mm adjustment range, you can dial in the exact end-of-travel position during commissioning without adding external stops.
This adjustable window creates a usable travel range of 105-135mm, perfect for product changeovers. The 40mm rod and M36x2 thread handle high side loads, while the extruded aluminum barrel incorporates sensor grooves on both sides. It uses PT tapered ports and offers variable air cushions at both ends to decelerate heavy loads smoothly.

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 SAIJ160BX135-30S Is Used
Heavy Press Tuning
Fine-tune the 105-135mm travel window during machine setup to apply exact clamping force without recalibrating the entire line.
Corrosive Assembly Lines
Rely on the SUS304 stainless steel rod and robust 160mm bore to execute heavy assembly pushes in washdown or chemically exposed environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-30S the Right Cylinder?
The 30mm rear adjuster lets you fine-tune the retract position on the fly, which is far more efficient than swapping out a fixed-stroke SAI cylinder for every new job. Because the stroke is 135mm, external guides are recommended to manage side loads on the 40mm rod. To replace an ISO 15552 cylinder, match the 160mm bore, 135mm stroke, PT ports, and SUS304 rod material.
The rear screw acts strictly as a travel stop, not a lock, and the air cushions only manage deceleration. Neither will hold a load without live air pressure. If your setup requires true load-holding, consider the SAIL pneumatic lock or BSAI clamp-lock series. Mounting options for this profile cylinder include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX135-30S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm, creating a usable travel window of 105-135mm from the 135mm nominal stroke. It functions as a mechanical stop for end-position tuning and does not lock the load without air pressure.
