About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-50S
The AirTAC SAIJ160X135-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 135 mm travel to a precise 85-135 mm window during commissioning. Delivering massive thrust, it pushes with 14074 N at 0.7 MPa and pulls with 9425 N at 0.5 MPa. This bore features a robust 40 mm piston rod, G3/4 ports, and 50 mm cushioning at both ends to manage heavy kinetic energy.
This specific SKU incorporates a SUS304 stainless steel rod (code B) for superior corrosion resistance and ships with a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper allows fine end-position tuning without adding external stops or swapping the cylinder.

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 SAIJ160BX135-50S Is Used
Heavy Press Fine-Tuning
Dial in the exact 85-135 mm end-position during machine setup to accommodate varying material thicknesses without replacing the cylinder.
Product Changeover Stops
Adjust the rear stopper on the fly to handle different package sizes on a packaging line, saving downtime on physical stop modifications.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for heavy-duty positioning tasks in washdown or mildly corrosive manufacturing settings.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-50S the Right Cylinder?
The 50 mm adjustment range is ideal for product changeovers on a line, letting operators set variable end-stops on the fly. Because the 135 mm stroke exceeds the 300 mm threshold, side-load is less of a concern, but the heavy 40 mm rod still requires external guiding for offset loads.
When specifying an ISO 15552 replacement, match the 160 mm bore, 135 mm stroke, 50 mm adjustment, PT tapered port thread, and the -S magnet requirement. Remember that the rear adjuster functions strictly as a travel stop, not a lock; the cylinder cannot hold a load without live air. For true pneumatic load-holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead. Mounting options are limited to 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 SAIJ160BX135-50S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 135 mm down to a minimum of 85 mm. This creates an 85-135 mm adjustable travel window for fine-tuning end positions without swapping components.
