About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-100
The AirTAC SAIJ160X400-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 400 mm nominal stroke that can be dialed back by up to 100 mm, yielding a usable travel window of 300-400 mm for precise end-position tuning. Equipped with a SUS304 stainless steel rod, it handles heavy loads with a push force of 14074 N at 0.7 MPa and uses PT tapered G3/4 ports.
This heavy-duty actuator relies on its 40 mm rod and M36x2 thread to withstand significant side loads, though the 400 mm travel length still necessitates an external guide for optimal performance. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU lacks a magnet, the design supports AirTAC CMSE reed and DMSE electronic sensors when needed.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-100 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance within the 300-400 mm window during machine commissioning to accommodate varying material lengths without mechanical rebuilds.
Heavy Product Changeover
Quickly adjust the stroke by up to 100 mm on a packaging line when switching between different large-format product sizes, minimizing downtime.
High-Force Positioning
Leverage the 14074 N push force at 0.7 MPa to move and position heavy industrial assemblies securely into a machining station.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-100 the Right Cylinder?
Select this 160 mm bore actuator when an application demands high thrust—delivering 10053 N push force at 0.5 MPa—that a 125 mm bore cannot provide, while avoiding the massive 15708 N output of a 200 mm cylinder. The 100 mm adjustment range is ideal for product changeovers, allowing operators to fine-tune the retract end position without swapping cylinders or adding external stops. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the 400 mm stroke exceeds the 300 mm threshold, an external guide is recommended to prevent excessive rod wear. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for dead-air load holding, consider an AirTAC SAIL or BSAI cylinder. To replace an ISO 15552 cylinder, match the 160 mm bore, 400 mm stroke, 100 mm adjust, PT G3/4 ports, and the specified mounting hardware.
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 SAIJ160BX400-100 FAQ
It features a rear external stopper that allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 300-400 mm, enabling fine-tuning of the end position without changing the cylinder.
At a 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. The maximum push force is 18095 N at 0.9 MPa.
