About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX20-10S
The AirTAC SAIJ160X20-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 10 to 20 mm, allowing you to dial in the exact end position without adding external stops. Equipped with a SUS304 stainless steel rod, it delivers 10053 N of pull force at 0.5 MPa and uses PT tapered ports.
This adjustable-stroke model includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear stopper allows fine end-position tuning during commissioning. The adjuster acts solely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX20-10S Is Used
Short-Stroke Tuning
Dial in precise 10 to 20 mm end positions for clamping or pressing without installing external physical stops on the machine frame.
Product Changeover
Quickly adjust the retract distance on a production line to accommodate varying part sizes using the rear adjustment screw.
High-Force Positioning
Leverage 10053 N of pull force in a compact footprint for heavy-duty, short-travel assembly and riveting tasks.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX20-10S the Right Cylinder?
Choose this 160 mm bore when an application demands high force in a very compact travel window, stepping up from a 125 mm bore that provides 5734 N of pull force at 0.5 MPa. The adjustable 10-20 mm travel is ideal for product changeovers on a line, letting you fine-tune the retract end without swapping the cylinder. For load-holding without live air, consider an AirTAC SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
As a dimensionally interchangeable ISO 15552 cylinder, it matches replacements using a 160 mm bore, 20 mm stroke, PT ports, and a -S magnet. It supports the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR mounts. Because the stroke is short, side-load risks are minimal, but the robust 40 mm rod and M36x2 thread handle high mechanical stress effectively.
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 SAIJ160BX20-10S FAQ
The rear adjuster screw lets you shorten the effective travel from the nominal 20 mm down to 10 mm, giving a 10-20 mm usable window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, it provides 10053 N of pull force and 14074 N of push force. The cylinder uses a SUS304 stainless steel rod and PT tapered ports for high-force, durable operation.
