Single & Double Bonded Bushes (Suspension Bushings)

AVMR have a fairly wide range of off-the-shelf single and double bonded bushes (bushings) but we can manufacture almost any bush on the market.  We have tooling to manufacture more bushes than in the below list, however these have been de-listed due to low demand.  Please contact us if you cannot see a bush you require.

It can be hard to see the difference between single and double bonded bushes, but the key difference is whether the outer tube is bonded or not.  For some of our bespoke product customers the outer tube must be bonded as the outer tube must not slip relative to the rubber.  Note: The way that we bond is particularly strong - the rubber will break before the bond does.

A single bonded bush starts life as an SAB Bush, and then has an outer tube fitted with an interference fit to pre-compress the rubber. As per the SAB bush, it is intended for lighter axial and torsional/rotational loads, as the outer tube will slip beyond a point. That said, slipping of the rubber in rotation can be desirable for some applications. Note: B bushes are available as SABs and can typically be made into peened bushes.

A double-bonded bush eliminates the opportunity for rubber to slip. Under much higher forces than it would take for a single bonded bush to slip, the rubber in a Double Bonded Bush will tear. There are clear advantages of a double-bonded bush, including the multi-directional forces they can withstand. Over time, these have become the vehicle suspension standard.. and we make a lot of them.

We have options on plating, product size and materials used for both the substrate and the rubber, so get in touch if you cannot see something that meets your needs.
