About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX105-20S
The AirTAC SAIJ160X105-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust thrust up to 10053N pull at 0.5 MPa. It features a SUS304 stainless steel rod and an integrated magnet for position sensing. This made-to-order configuration provides a usable travel window of 85-105mm, allowing you to dial back the nominal 105mm stroke by up to 20mm during commissioning.
Instead of swapping out physical components to achieve precise end-positioning, the rear stopper screw lets you fine-tune the retract distance on the fly. The cylinder operates at 30-500mm/s and includes variable air cushions at both ends to decelerate heavy loads smoothly. For load-holding without live air pressure, this adjuster acts only as a travel stop, so you would need an external rod lock or a SAIL series 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 SAIJ160BX105-20S Is Used
Heavy Press Tuning
Fine-tune the exact bottoming position of a heavy press during initial setup, using the 20mm adjustment window to perfect the crush distance without machining new spacers.
Product Changeover
Rapidly adapt a heavy-duty diverting mechanism on a conveyor line when product sizes change, dialing in the new retract stop from 105mm down to 85mm in seconds.
Assembly Station Setup
Commission a large assembly station by adjusting the end-stop to perfectly seat large components, relying on the 10053N pull force to handle the heavy tooling.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX105-20S the Right Cylinder?
Choose this 160mm bore when a 125mm cylinder (offering 5734N pull at 0.5 MPa) cannot move your payload, but you want to avoid the massive frame of a 200mm unit. The adjustable 85-105mm travel window is ideal for product changeovers on a line, letting you set exact retract distances without adding external stops. To replace an ISO 15552 cylinder, match the 160mm bore, 105mm stroke, PT tapered port threads, SUS304 rod material, and the -S magnet requirement.
Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. The -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. Although the stroke is relatively short, always ensure external guides support the load to prevent excessive side-loading on the rod.
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 SAIJ160BX105-20S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 20mm. This creates a usable travel window of 85-105mm, allowing precise end-position tuning without changing the cylinder or adding external stops.
