Eliminates wear on pivot lugs
What causes lug wear?
Meet Jonny who talks about lug wear and how lugs with a conventional straight pin are worn due to three reasons. Do you know which ones - and that you can prevent the formation of lug wear?!
See how Expander reduces stress in the axle
Replacing a traditional straight pin with an Expander System pivot pin of the same diameter maximizes safety and minimizes the risk of axle breakage. The system’s double sided axial locking makes a stronger machine.
The axle ends are fixed in the lugs by the expanding sleeves and the load case cuts the axle stress in half.
“We use Expander System because we know it pays off.”

We did not need to machine the lugs. Expander’s pivots fixed the oval shape and we got rid of the vibrations!

The Expander System eliminates wear on pivot pins and cylinder rod ends. The solution is used as a direct replacement for existing straight pins, without re-design or alteration. It is installed straight into the worn lugs, making it a perfect solution for field installation.
The Expander System is an expanding pivot pin that does not require line boring, allowing for more throughput through the workshop. Questions? Email us at firstname.lastname@example.org.
