About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-20S
The AirTAC SAIJ160X135-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 115-135 mm usable travel window by allowing you to dial back the nominal 135 mm stroke by up to 20 mm.
This variant features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance and includes a magnet (-S) for compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the unit uses PT tapered port threads (G3/4). The rear adjuster acts purely as a mechanical stop to fine-tune the end position at commissioning; it is not a lock, so live air is required to hold the load.

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 SAIJ160BX135-20S Is Used
Heavy-Duty Forming
Dial in the exact 115-135 mm retract position during stamping or forming setup, absorbing heavy impact forces with up to 10053 N of pull at 0.5 MPa.
Product Changeover
Quickly adapt the end-stop for varying product sizes on a packaging line without physically replacing the cylinder or bolting on external stoppers.
Automated Assembly
Leverage the SUS304 rod and DMSE electronic sensors for robust, corrosion-resistant actuation in harsh industrial automation environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-20S the Right Cylinder?
The 20 mm adjustment window is ideal for product changeovers on a line, letting you shift the retract stop without swapping the cylinder or adding external stops. If you need to hold a load without continuous air pressure, this standard SAIJ adjuster will not suffice; instead, consider the SAIL air-released lock or BSAI clamp-lock variants.
Although 135 mm is a moderate stroke, the substantial 40 mm rod diameter and M36x2 thread handle high side loads well. For longer unsupported travels, an external guide is recommended. This SAIJ model supports the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.
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 SAIJ160BX135-20S FAQ
It features a rear adjusting screw that allows you to shorten the effective stroke by up to 20 mm. This provides a usable travel window of 115 to 135 mm, letting you fine-tune the retract end position at commissioning without changing the cylinder.
At a 0.7 MPa operating pressure, the push force is 14074 N and the pull force is 9425 N. At 0.9 MPa, the push force increases to 18095 N.
