4.0" inch Bore Budget Priced AG Style Hydraulic Cylinder available in various Strokes from 4" to 48 inches.

These are high-quality double-acting cylinders. Sizes are common AG style, easily interchanged with many other AG ram brands.
This 4.0" inch bore cylinder has a strong 1.75" inch (45mm) diameter rod.
It has dual UNO 3/4" UNO ports for easy and flexible hose connection options.
These 4" cylinders come with 1" pins and safety lynch pins (clips) at both ends.
(note 1.5" bore cylinders have 3/4 pins and 5" bore cylinders have 1-1/4 pins)

Please see the accompanying photos and charts for
Full dimensions & weights
Maximum forces / pressures that can be applied (under extension and retraction).
As with all cylinders, the longer the stroke, the less force (pressure) that can safely be applied during extension.

For Example
AG 4012-175 (4" bore, 12 inch stroke, and 1.75 dia Rod ) can push 16.8 tonnes at 207 bar (3,000 psi) ,
whilst an AG 4048-175 (4 bore, 48 inch stroke, and 1.75 inch dia rod) can only safely push 2.3 tons without the rod buckling.
Please see the maximum force chart in the photos.

IMPORTANT Note: If the load (in ton) you are looking push is more than the number indicated on the chart you will have to move up in bore or rod size or add another Cylinder.

• If the load (in ton) you are looking push is more than the number indicated on the chart you will have to move up in bore or rod size.
• The values are based on a safety factor of 2 with the cylinder operating vertical and fully guided.

• For horizontal or operating in an arc these values may have to be reduced.

Single Acting Use
If the intended use is for Single acting setup we highly recommend the following,
To assist in preventing the ingress of contamination we recommend at a minimum
the installation of a breather plug into the air side cylinder port.
Connecting a hose from the air/breather side back to the oil reservoir can further increase cylinder life.

The warranty is 12 months. (our Australian made cylinders have 2 Year warranty, see listing below)
